  1. GENERAL INFORMATION [§135.427]‌

     
     

     This manual sets forth Maritime Helicopters’ procedures and policies that are acceptable to the Administrator of the Federal Aviation Administration. Maritime Helicopters will keep this manual current with revisions as necessary. Maritime Helicopters maintains one copy of this manual in current form at the principal base of operations located at, 3520 FAA Rd., Homer, AK. The Director of Maintenance will maintain the original copy of this manual. He/She will have the responsibility to keep it current. Maintenance shall follow policies and procedures outlined in this manual.

     
     

     Maritime Helicopters disburses copies of this manual in the following manner:

     
     

     • A locked PDF (portable document format) version of the General Maintenance Manual shall be made available on the Maritime Maintenance Portal Web Site or is stored on the base computer and available for all Maritime Helicopters’ employees at each base of operations. All Maritime Helicopters’ personnel must use this manual in conducting all maintenance. All maintenance personnel shall have knowledge of this Manual in its entirety.

     • The Director of Maintenance will have a copy of this manual at their office. It will be the Director of Maintenance responsibility to maintain a current copy on the Maritime Helicopters internet-based manuals.

     • Other persons as assigned.

       Maritime Helicopters has also furnished the Alaska Flight Standards District Office (FSDO) of the Federal Aviation Administration (FAA) with a current and complete copy of the manual. The Director of Maintenance will furnish the FAA with all requests for changes and additions to this manual in a timely manner.

       
       

       Great care has been taken to assure that this manual is not contrary to any applicable Federal regulations, Maritime Helicopters’ Operating Certificate, or Maritime Helicopters’ Operations Specifications. However, errors do sometimes occur despite all efforts. If you find such a conflict; the regulation, certificate, or operations specification will take precedence. You are required to bring any such conflicts to the attention of the Director of Maintenance for correction.

       1. CAS Memorandums (MEMOS)‌

          When preparing a Company Manual of any kind, it is not possible to anticipate all of the issues and questions that might arise and need to be addressed. The Continuing Airworthiness Surveillance (CAS) memo system has been developed to assist in the timely dissemination of information of important or urgent nature. This information shall generally be included in the appropriate manual at its next revision or will have an effective time limitation attached to it. CAS Memos will be used to impart significant maintenance related information when needed, to answer questions at the hangar or company level, or to supplement, but not change, the guidance contained in this General Maintenance Manual. CAS Memos will not be issued with an expiration date. Periodically, each Memo will be reviewed for continued validity and pertinence. Memos deemed no longer valid or pertinent will be canceled, while others may be incorporated into a company manual as applicable.

          
          

          Operations, Safety, or Maintenance CAS Memos are sent to all applicable employees by either a hard copy or through the email system. Each CAS memo issued by the Operations, Safety or Maintenance Departments is delivered to the Office Coordinator to be distributed. The memos are identified as Operations (O), Safety (S), or Maintenance (M) and numbered consecutively with the first two digits representing the year followed by the consecutive number of the memo.

          
          

          All employees receiving a CAS memo by hard copy or email must reply utilizing the acknowledgement sheet attached to the memo or by email and a record of receipt is kept ensuring all messages have been read.

          Hard, Electronic PDF, or internet accessible copies of current CAS memos are maintained at each field location and by the Maintenance Office. The Director of Maintenance or designee may issue Maintenance CAS Memo’s.

  1. MAINTENANCE‌

     
     

     1. Aircraft Airworthiness Check [§135.25]‌

        All aircraft will have an Airworthiness Check (Daily Inspection) performed by a company mechanic in accordance with the applicable Maintenance Manual. This shall be performed on days the aircraft is in service, after the last flight or before the first fight of the day. When a Airworthiness Check has been completed, the mechanic shall place a green sock over the cyclic indicating to the pilot the check has been performed.

        
        

        It is expected that if a mechanic is physically present, this check shall be performed by the mechanic each flight day. The mechanic shall also meet with the duty pilot to review the Aircraft Status CALM Report to include any pen and ink changes to ensure awareness of items coming due. Pilots and mechanics must concur that all items coming due are noted on the Aircraft Status CALM Report and the Items Due section of the Aircraft Log Book.

        
        

        If maintenance discrepancies are identified during the Airworthiness Check, an appropriate log book entry shall be made by the individual who made the discovery and an appropriately rated mechanic contacted to perform corrective action. Any time the aircraft is unairworthy, the mechanic shall place a red sock over the cyclic to alert the pilot the aircraft is not ready for flight. It shall be removed when the discrepancy/discrepancies have been corrected. The red sock shall also be placed on the cyclic if the mechanic is conducting maintenance on the aircraft and items such as flight controls have been disconnected.

        
        

        If discrepancies are identified during an Aircraft Status CALM Report review, the aircraft shall immediately be removed from service until an appropriately rated mechanic resolves the discrepancy.

        
        

        In the absence of a company mechanic, the pilots preflight shall be the equivalent of an aircraft Airworthiness Check. The pilot shall record the preflight / airworthiness check by signing the appropriate section of the Helicopter Log. The pilot shall utilize the preflight section of the appropriate approved Rotorcraft Flight Manual. This check shall include a review of the Aircraft Status CALM Report.

        
        

        Once the pilot completes a preflight, the aircraft is considered to be ready for flight. A mechanic shall not open any cowling and/or perform any maintenance unless the pilot is notified.

        
        

     2. Aircraft Equipment and Conformity Check [§135.25]‌

        The following procedures shall be accomplished prior to adding aircraft to the Operation Specifications.

        NOTE: These procedures do not have to be completed in sequential order.

        
        

        • All historical records shall be audited. The records will be audited for any applicable instructions for continued airworthiness, to be tracked on the Aircraft Status CALM Report .

        • A certificated mechanic will be assigned to complete the “Equipment Installed” worksheet, so these items can be addressed in the applicable Maritime Helicopters “Minimum Equipment List” (MEL).

        • The “Conformity Check” will confirm that the aircraft and equipment meet the applicable regulations, required instrumentation and equipment have been approved and are in operable condition and the ATC transponder equipment meets the performance and environmental requirements of the TSO as per §135.143.

          
          

     3. Continuous airworthiness Maintenance Program (CAMP) {§135.411, §135.415, §135.423 thru §135.443] and Approved Aircraft Inspection Program (AAIP) [§135.411, §135.413, §135,421]‌

  1. General‌

     Maritime Helicopters Federal Aviation Administration Approved Continuous Airworthiness Maintenance Program (CAMP) for 10 seats or greater and Approved Aircraft Inspection program (AAIP) for 9 or less seats have been prepared for use for helicopters used in air taxi operations conducted under 14 CFR 135.

     
     

     The CAMP/AAIP are based on the manufacturers' recommended inspection program. All items pertinent to the continued airworthiness of this aircraft make and model are included, though possibly rearranged.

     
     

     These programs contains time intervals between checks, inspections and overhauls, and contains detailed procedures or reference to documents containing detailed procedures to perform checks, inspections, maintenance, overhaul and repair, and structural inspections. The Preamble of each aircraft model CAMP/AAIP contains detailed instructions on how to comply with the Continuous Airworthiness Maintenance and Approved Aircraft Inspection Programs.

     
     

     Removal, installation, servicing and repairs of systems and components including and after maintenance checks and inspections are accomplished in accordance with the manufacturer's maintenance procedures, Instructions for Continued Airworthiness, or other acceptable data for the specified part or component.

     
     

  2. Administration‌

     The Director of Maintenance has overall responsibility in administering the program, including the assignment of qualified personnel to schedule and perform inspections and maintenance.

     
     

  3. Scheduling‌

     The Director of Maintenance or the mechanic where the aircraft is assigned is responsible for monitoring the aircraft flight times and scheduling the aircraft for inspections and additional required maintenance. The Director of Maintenance or the mechanic shall insure that special tools, equipment, and parts needed are available.

     
     

     NOTE: Mechanics shall review the CALM report for upcoming CAMP/AAIP inspections that may require special tooling they currently don’t have available and may need to request.

     
     

  4. Personnel‌

     The CAMP/AAIP checks, inspections and maintenance are to be performed by properly certificated mechanics with an airframe and power plant rating or by repairmen from an appropriately rated Certificated Repair Station and are qualified, trained, and authorized as documented in the Maritime Helicopters maintenance training records.

     
     

  5. Responsibility for Maintenance‌

     A mechanic's signature, date, certificate type and number entry in the helicopter logbook for any maintenance, check or inspection performed indicates that the mechanic has performed the work or determined by inspection that the work signed for was performed in accordance with the CAMP/AAIP or other acceptable or approved data, and so CFR as the work performed is concerned the aircraft, except for recorded discrepancies, is approved for return to service.

     
     

     The Director of Maintenance is responsible for ensuring the personnel assigned to a specific task are properly qualified, trained, and authorized to accomplish that task. Certificated mechanics or repairmen are responsible for the maintenance tasks they perform or supervise. Responsibility for each step of the accomplished maintenance or inspection is borne by the person signing for that step.

     
     

  6. Inspections‌

     Detailed procedures for conducting inspections under the CAMP/AAIP are found in the applicable aircraft Maintenance Manual. The checks and inspections contained in the CAMP/AAIP are accomplished using check or inspection guides, inspection forms, or in accordance with manufacturer's manuals. For check and inspection guides that do not have a place on the guide for the mechanic’s return to service signature, a logbook entry is required for returning the aircraft to service.

     
     

     The inspection forms have a block for the mechanic to initial for each item inspected. The end of each form has a signature block to identify each mechanic that initialed an inspection item. The mechanic’s initials in the block provided indicates that he accepts the responsibility that the item was performed in accordance with the CAMP/AAIP form in use and if the item was not in an airworthy condition, a discrepancy has been entered in the

     
     

     aircraft record, (logbook or work order). When all blocks are initialed, a logbook entry for completion of inspection is made. Upon completion, the inspection forms are returned to Maritime Helicopters Maintenance Department, where they are filed by "N" number until such time that the particular inspection is repeated.

     
     

  7. Additional Inspections‌

     Each aircraft status sheet (CALM) contains additional inspections or tasks for systems and components requiring inspection at specific intervals not listed in the CAMP/AAIP. The status sheet lists the item to be inspected, the interval, the inspection or task required, and reference to acceptable data for the performance of the inspections or tasks.

     
     

  8. Maintenance Time Limitations‌

     The inspection limits of aircraft maintained under Maritime Helicopters Continuous Airworthiness Maintenance Program and retirement, overhaul limits on the aircraft status sheet shall be followed. For Maritime Helicopters aircraft not maintained under the CAMP/AAIP, the manufacturer’s established time limitations will be adhered to and retirements/overhauls on aircraft status sheet complied with.

     
     

     The maintenance time limitations for the aircraft, airframe, engine, installed equipment, installed systems and installed emergency equipment are derived from the aircraft Type Certificate Data Sheet as amended, the manufacturer’s most recent limitations and Department of Transportation guidelines.

     
     

  9. Adding Aircraft to the CAMP/AAIP‌

     The following procedures shall be used when entering an aircraft on Maritime Helicopters’ Continuous Airworthiness Maintenance Program;

     
     

• The aircraft registration number, make, model, and serial number shall be on the Operations Specification List of Approved Aircraft.

• A bridging document will be created and remain on file for 1 year. The document shall determine by outline which inspections must be complied with before bringing the aircraft onto the CAMP. These inspections shall be entered on to the aircraft logbook and signed off before the aircraft entered onto the program.

• Once the bridging requirement inspections have been complied with, the Aircraft and Engine Log Book shall have an entry made stating that the aircraft and engine are now being inspected in accordance with Maritime Helicopters Continuous Airworthiness Maintenance Program

• The Maritime Helicopters CAMP/AAIP inspection schedule is based on manufacturer recommendations, with some differences. Maritime Helicopters has decreased the maintenance interval on some items and has added maintenance intervals on some items that are not included in the manufacturer’s recommendations. Due to this more stringent maintenance program, aircraft being added to the Maritime Helicopters CAMP/AAIP will have a period of up to 500 flight hours to be brought into compliance with the Maritime Helicopters CAMP/AAIP Maintenance Time Limitation on items with a decreased or added maintenance interval, but in no case shall exceed the limitations of the manufacturer.

  
  

  1. Removing aircraft from the CAMP/AAIP‌

     Aircraft removed from either the CAMP or AAIP program shall have an annual inspection performed prior to being released for flight or shall be accepted into the inspection program of another operator prior to being released for flight. A list of the status of the existing inspection program will be provided to the new owner.

     
     

     The following entry will be made in the log book:

     
     

     “This aircraft was removed from a CFR Part 135 maintenance program and must be inspected in accordance with CFR 43.15 Part (a), (a)(1), (b), (c), and (c)(3) before returning to service.”

     
     

  2. Required Inspection Items (RII)‌

  RII inspection items, policies and procedures are listed in the CAMP program.

  
  

  1. Contract Maintenance [§135.437]‌

     Maritime Helicopters Air Carrier Certificate ENRA619D, has arranged with Maritime Helicopters Certified Repair Station ENRR619D and Fairbanks Satellite Repair Station EN2D619D to be the primary contractor to conduct its required inspections and the repair and overhaul of components and appliances in accordance with Maritime Helicopters Inc.

     Other outside contractors will be evaluated, before utilizing them, on a case by case basis to ensure Maritime Helicopters Inc. and applicable regulatory standards are met.

     
     

     The Air Carrier will ensure the airworthiness of its aircraft by conducting audits. The Air Carrier, through its Continuing Analysis and Surveillance system (CASS), audits the Repair Station and its vendors to ensure compliance with all maintenance programs and the Federal Aviation Regulations.

     
     

     The Vendor Audit program is conducted by the Inspection Department, and questionnaires are sent electronically or in hard copy form to the individual vendors every two years. A current vendor list is maintained in the Maintenance Records Office.

     
     

     Should maintenance or servicing needs occur outside of Maritime Helicopters Inc.’s normal operation area, the pilot in command becomes responsible for:

     
     

• Obtaining permission from the Director of Operations, Director of Maintenance, or his representative, prior to having corrective maintenance performed.

• Ascertaining that maintenance personnel involved are either employees of an FAA Certified Repair Station or are properly certificated airframe and power plant mechanics or certificated repairmen, as appropriate. The pilot in command shall ensure that the persons involved are subject to the requirements of an FAA Approved Drug Program in accordance with 14 CFR Part §135.251(b).

• Assuring that maintenance performed is properly recorded and signed off in the A/C logbook by those involved.

• All inspections performed on aircraft that are being operated under Maritime Helicopters' Continuous Airworthiness Maintenance Program by maintenance facilities other than Maritime Helicopters’ shall be done in accordance with Maritime Helicopters’ Continuous Airworthiness Maintenance Program and Maritime Helicopters’ Operations and General Maintenance Manuals. A copy of the CAMP shall be provided by either the DOM or Chief Inspector.

  
  

  1. Contract Maintenance Providers [§135.426(h)]‌

     Maritime Helicopters shall provide to its FAA Certificate Holding District Office, in a format acceptable to the FAA, a list that includes the name and physical (street) address, or addresses, where the work is carried out for each maintenance provider that performs work on any MHI aircraft certificated for 10 seats or greater. The list shall include a description of the type of maintenance, preventive maintenance, or alteration that is to be performed at each location. The Chief Inspector shall maintain the list and is responsible to update with any changes, including additions or deletions. Any updates to the list must be provided to the FAA in a format acceptable to the FAA by the last day of each calendar month.

     
     

     The current list is located in Appendix G of this manual.

     
     

  1. Aircraft Maintenance Standard Practices‌

     When an aircraft is going out of service for any kind of maintenance, keep your pilot informed. Install the “Red” cyclic sock as stated in the Maritime Helicopters General Operations Manual. When any maintenance action has been performed, have another company mechanic (or pilot if no mechanic is available) inspect your work if available. Be thorough, review the task performed as prescribed in the maintenance manual and inspect the work performed using a bright flashlight and mirror. Inspect the entire area, for correct installation, foreign objects, other anomalies, etc. Challenge each other and ask questions. Ask the pilot to review the work performed if a mechanic is not available.

     
     

     When performing any task let the pilot know what is going on. Work as a team. If you go out to the aircraft to check on something, and you open a cowling, let the pilot know so he or she can double check the cowlings.‌‌‌‌‌‌‌

     
     

     When performing any type of maintenance, all mechanics must follow the procedures established in the appropriate aircraft maintenance manuals to include a logbook entry. All maintenance actions, inspections, troubleshooting, preventive maintenance, etc. require a maintenance logbook entry in accordance with CFR 43 indicating maintenance was performed on the aircraft.

     Do not get complacent when inspecting or performing maintenance on an aircraft and always communicate with the pilot. In the Human Factors arena, "Fatigue" has been identified as one of the primary causal factors of accidents and incidents for pilots and mechanics. Fatigue goes hand in hand with other human error causes including complacency, distraction and lack of awareness.

     
     

     At anytime a mechanic is fatigued or stressed and can no longer perform safety of flight issues, the mechanic is expected to stop working and notify the Director of Maintenance

     
     

     1. Aircraft Ground Movement‌

        During aircraft movements in and out of MHI facilities the following steps are required to ensure the safety of the personal involved and reduce the chance of aircraft damage. Each location may have other procedures that must be followed. Check with the manager at customer bases to ensure the aircraft is being handled IAW their required guidelines.

        
        

        1. Tug a Lug Use

           • The use of a Tug a Lug is not authorized without prior training.

           • Movement in and out of under the aircraft requires the removal of the aircraft pegs to limit the chance of contact with the airframe, cross tubes, and antennas.

           • Confirm pegs are installed in correct location for the type of airframe it is being used on.

           • Ensure all four pegs are aligned with the crosstube prior to lifting the aircraft.

           • During movement avoid uneven ground. If uneven ground is unavoidable lower aircraft to the lowest level possible for the skid tubes to clear the ground.

           • Do not leave the Tug A Lug under the aircraft once the aircraft has been moved due to battery proximity to fuel cells (OSHA). NEVER CHARGE A TUG A LUG WHILE UNDER AIRCRAFT.

             
             

        2. Ground Handling Wheels

           • Confirm the wheels are installed in the correct position to balance the tail in a neutral position.

           • Avoid having head and body over wheels while pumping jacks.

           • Have a person holding the tail prior to jacking to prevent the airframe from rocking on to its tailboom.

           • The vehicle used to move the aircraft must be sufficient in weight to prevent the aircraft from “pushing” the tow vehicle.

             •

           • Verify rotor clearance of doors and ceiling prior to movement of aircraft.

           • Some locations such as Valdez and Fairbanks small hanger require the use of a “block” in some two bladed helicopters to prevent contact with the ceiling. The block must have a flag connected to it to prevent being left in the aircraft during preflight.

           • Doors that open vertically must be all the way up and stopped when moving aircraft in and out of the facility.

           • Verify there is enough personal in place to spot blind areas. If there are not enough spotters ask for assistance prior to moving the aircraft. A minimum of two personal is preferred if possible.

           • Verbalize intentions prior to lifting or moving the aircraft.

           • When available utilize floor protectors to prevent damage to the hanger floors.

           
           

     2. Ground and flight Maintenance‌

        Certain maintenance activities require the aircraft to be ground run or flown to complete the maintenance action. During periods of ground operation, cowling may be removed and test equipment may be attached. It is the responsibility of both pilot and the mechanic to ensure safety is the first concern.

        
        

        Exposure to Foreign Object Damage (FOD - See Paragraph 5.4) is increased due to unusual equipment around and on the aircraft and the aircraft being ground run without all cowling installed. Loose equipment must be removed from the aircraft and area prior to starting the aircraft. Any time a Ground Run or Pilot Operational Flight is recorded in the aircraft log book, the following entry shall be made in the log book;

        
        

        “FOD check required prior to aircraft ground run (or pilot operational flight). [Name][Date][Certificate Number]” This check may be signed off either by a certificated mechanic or pilot.

        Proper safety protection must be for the type of ramp operations anticipated. Remember hearing protection prevents hearing and extra effort is needed to expand our visual awareness. Extra caution is needed around spinning main and tail rotors and spinning shafts.

        
        

        Ground support equipment such as ground power units, battery conditioning apparatus, hydraulic test carts, etc. shall be utilized and maintained in accordance with the equipment manufacturer’s manuals.

        
        

        Aircraft shall not be “run-up”, “ground turned” or otherwise operated on the ground with any cowl, access door, or panel unsecured if there is a potential for contact with any moving part on an aircraft including but not limited to: propellers, main rotor blades, tail rotor blades, drive shafts, control surfaces, actuators, landing gear, control tubes, control cables. Maritime Helicopters mechanic or pilot shall attend any open cowl, access door, or panel during “run-up”, “ground turned” operations.

        
        

     3. GPU Use‌

        For the first start of the day, when available, a Ground Power Unit (GPU) shall be used to provide electrical power to the aircraft. The pilot. and operators of the GPU shall discuss when the GPU is to be disconnected and hand signals to be used. The GPU will be within pilots view during aircraft operation. Power cables shall be routed away from the aircraft when possible. If power cables cannot be routed away from the aircraft, the GPU will be removed from the area after the aircraft start is complete during ground idle prior to 100% rotor speed.

        
        

     4. Aircraft Operation with Cowlings Removed‌

        Maintenance activities require the ground operation of the aircraft with cowling removed. Cowlings shall not be removed or installed while the engines or rotors are turning. Mechanics shall store cowlings either in the aircraft, a vehicle or a building when not installed on the aircraft. Cowlings shall not be left unattended in the open. Aircraft shall not be flown without all cowlings installed.

        
        

     5. Aircraft Operation during Adjustments‌

        Often adjustments during engine operation are necessary to complete a maintenance action. Mechanics shall ensure only the tools necessary to perform the adjustment are taken to the site of maintenance.

        
        

        Parts or components safeties that are removed during adjustment while performing maintenance must be reinstalled prior to flight even if that flight is for maintenance.

        
        

     6. Use of Ladders, Carts and Work Stands‌

        Ladders and/or carts shall be used around running aircraft only when necessary. Vacant ladders are not to be left standing but laid flat on the ground. Carts shall be moved into the hangar or vehicle when not being used.

        
        

     7. Attachment of Test Equipment‌

        Often test equipment is required during ground run and flight of an aircraft. The cables and other items of equipment must be secured properly to prevent entanglement during operation. Both the pilot and mechanic shall

        
        

        check clearances of equipment installed on rotating parts prior to operating the engines. Mechanics shall check cables for security and full range of movement of controls when applicable.

        
        

     8. Fueling Procedures‌

        Refer to the Maritime Helicopters fuel quality assurance manual for fueling procedures located in the maintenance office.

        
        

     9. Defueling Procedures‌

        Refer to the Maritime Helicopters fuel quality assurance manual for defueling procedures located in the maintenance office.

        
        

     10. Fuel Sampling Procedures‌

         A fuel sample must be taken before first flight of the day. Fuel will be collected in a clean, clear container. The fuel sample will be visually checked for moisture content and debris. When the aircraft is cold-soaked, any water or moisture suspended in the fuel may be frozen; look for ice crystals in a cold-soaked fuel sample.

         
         

         The following steps for obtaining a fuel sample are recommended, although individual aircraft and / or circumstances may make other steps necessary.

         
         

         Basic steps for obtaining a fuel sample from a Maritime Helicopters aircraft:

         
         

         1. Make sure fuel sample jar is completely clean, clear and labeled with the aircraft tail #.

         2. Make sure fuel boost pump or fuel transfer pump switches or circuit breakers are in the off position.

         3. Plug in the battery, turn on the battery switch.

         4. With the fuel valve in the off position, take a fuel sample from the main tank sump drain.

         5. Check this fuel sample for water or debris before continuing.

         6. Turn on fuel valve

         7. Turn on fuel boost pump

         8. With fuel valve and boost pumps in the on position, take a fuel sample from the airframe fuel filter.

         9. Check the fuel sample for water or debris.

         10. Clearly label fuel sample jar with the aircraft registration number, current date, and the initials of the person taking the fuel sample

         11. Retain this fuel sample at least until another fuel sample is taken from that aircraft

         
         

     11. Tie Down and Securing Aircraft‌

         Maritime Helicopters Inc. personnel must, to the maximum extent practicable, ensure that the aircraft is protected against damage by vehicles, weather, or other outside sources. Company policy is aircraft are to be put in the hangar whenever possible.

         
         

         If the aircraft will remain outside overnight, personnel should ensure that:

         • The aircraft is parked properly.

         • Flight control locks are installed if available.

         • Plugs and covers are installed as necessary.

         • Rotors are secured to prevent damage.

         • Aircraft is secured to adequate tie down provisions.

         • The aircraft is locked if necessary.

         
         

         Precipitation is to be anticipated, so covers shall be used if they are available. High wind conditions should always be anticipated when securing aircraft outside. Addition instructions may be located in the Maritime Helicopters Inc. Operations Manual.

         
         

  2. Authorized Preventative Maintenance‌

     Pilots are authorized to perform preventive maintenance on certain items during remote area operations. A remote area is defined as any area where qualified maintenance personnel are unavailable or not readily available (greater than 4 hours and/or 100 miles) to perform preventive maintenance.

     
     

     CFR Part 43.3 paragraph (h) allows the pilot operating rotorcraft to perform specific preventive maintenance as described in CFR Part 43 Appendix A paragraph (c).

     
     

     Maritime Helicopters, Inc. pilots who have completed the Maritime Helicopters Pilot Preventive Maintenance Program training course are authorized to perform the preventive maintenance items.

     
     

     A logbook entry shall be made in the normal manner to document the preventive maintenance performed.

     
     

  3. Leak Check Requirements‌

     A leak check will be required on all Maritime Helicopters Inc. aircraft, regardless of operating certificate or maintenance program, whenever work is performed involving any fuel, oil, hydraulic, or pneumatic line or system. The leak check shall be noted with a description of the item to be checked as a separate entry in the aircraft logbook.

     
     

     If the leak check involves any oil and/or fuel components or lines, the aircraft shall be ground run at flight idle for 5 minutes while area(s) where maintenance was accomplished are observed by maintenance personnel. After 5 minutes, if no leaks are observed, the mechanic will signal the pilot to bring the aircraft to full RPM for another 5 minutes. If after 5 minutes no leaks are noted, the aircraft shall be flown for a minimum of 5 minutes.

     
     

     Once aircraft has returned and shut down, another inspection of decks is to be performed for any leakage.

     
     

     NOTE: The times are to allow all fluids to reach normal operating temperatures. Fuel and oil systems do not reach maximum pressures on the ground even at full RPM.

     
     

     NOTE: If the leak check was accomplished due to the removal/reinstallation or replacement of an engine or transmission, all times noted above are to be doubled with the flight portion being a minimum 20 minutes. The aircraft shall be shut down and reinspected before the flight portion.

     
     

     NOTE: If cowlings where removed for the ground run, aircraft must be shut back down and cowlings reinstalled prior to flight.

     
     

  4. Conditional Inspections‌

     Conditional inspections for unscheduled incidents including but not limited to, sudden stoppage, hard landing, over speed, over temp, over torque, compressor stall, compressor blockage, clutch slippage or any other incident or circumstance requiring special inspection will be accomplished using the criteria for that incident published by the airframe and/or the engine manufacturer.

     
     

  5. After Maintenance Checks and Inspections‌

     All after maintenance checks and inspections will be done in accordance with the manufacturers' maintenance manual unless otherwise noted in the Additional Maintenance and Inspection Schedule for each model.

     
     

  6. Additional Maintenance and Inspections‌

     Additional inspections determined by Maritime Helicopters to maintain aircraft in an airworthy condition are tracked in the Aircraft Status Sheet. Procedures for performing these inspections shall be found in the applicable AD, manufacturer's manual, service bulletins, industry standards, and/or Maritime Helicopters forms.

     
     

  7. Discrepancies‌

     All discrepancies discovered during the course of, or in between, scheduled inspections will be entered in the aircraft logbook. When the inspections are being performed by a certified repair station, the Repair Station personnel will enter the discrepancies on the Repair Station Work Order.

     
     

     All discrepancies affecting airworthiness will be corrected before approving the aircraft for return to service. Repairs will be accomplished using data that is acceptable to the FAA. For major repairs, data that is approved by the FAA will be used. The corrective action taken for each discrepancy will be entered in the aircraft logbook or on the Repair Station Work Order when the inspection is being performed by a certified repair station.

     
     

  8. Required Torque Check‌

     Each aircraft Maintenance Manual contains required torque checks and intervals. The Manufacturer Maintenance Manuals will be used as reference for all torque checks.

     
     

  9. Overhaul of Components‌

     Overhauls are accomplished by a certified repair station, or other approved facilities in accordance with the aircraft, engine, or accessory manufacturers’ manual. Each aircraft Maintenance Manual contains a table, which summarizes the overhaul schedule of the airframe and engine components and accessories.

     
     

  10. Emergency Equipment‌

      Emergency equipment installed in Maritime Helicopters aircraft will be maintained in an airworthy condition in accordance with the referenced data for each aircraft model.

      
      

  11. Teamwork Safety‌

  Any time there is more than one mechanic or mechanic(s) with a pilot working on an aircraft, verbal “call-outs” shall be used.

  
  

  If you intend to switch on power, announce your intentions in advance in so the other mechanic(s) or pilot in the vicinity of or working on aircraft electrical wires/components have time to be clear. They may need to let you know they are doing something that they cannot stop at that moment and do not want the power on.

  
  

  If you are going to turn the rotors/drive train, make an announcement “rotors turning” of “turning” so as the other personnel on the aircraft have time to move any body parts that may be injured by dynamic components or move tools/tooling that may cause damaged to a rotating component such as a drive shaft.

  
  

  All personnel working in and around aircraft should be aware of their operations that may present themselves as hazardous and let others know such as the lifting or lowering of the tug. When in doubt, make your intentions known.

  
  

  2.16 Airworthiness Information [§135.23, §135.411, §135.413]‌

  The Director of Maintenance is responsible for ensuring the airworthiness of all aircraft, engines, accessories, and appliances in the aircraft.

  
  

  The Approved Aircraft Inspection Program (AAIP), or Continuous Airworthiness Maintenance Program (CAMP). Inspections of the aircraft, engines, propellers, accessories, and appliances will be performed by an FAA approved repair station or an appropriate certified and trained mechanic.

  
  

  1. Extension Procedures for Overhauls and Inspections‌

     
     

     1. Introduction‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌

        Maritime Helicopters may at times need to request extensions of overhaul (TBO) schedules due to part(s) availability, personnel availability, equipment availability, maintenance scheduling conflicts, or any other unforeseeable circumstances. Since Maritime Helicopters maintenance is based upon the aircraft (airframe, engine, propeller and appliance) manufacturers recommended maintenance programs, written authorization for overhaul or inspection extensions from the manufacturer may be required. In addition, the manufacture may require the certificate holding office of the FAA to be informed of and approve the extension request prior to Maritime Helicopters exceeding any published overhaul or inspection intervals.

        
        

        In order that extension requests may be expedited and submitted to both the aircraft manufacturer and the FAA in a timely fashion, this section sets forth uniform procedures to be followed when extensions are required.

        
        

        NOTES:

        • Extensions are to be considered as non-routine maintenance practice, not standard operating procedure.

        • When an extension is needed, it is standard practice to request the maximum amount allowable by the manufacturer of the scheduled overhaul or inspection interval.

        • If the FAA denies the extension request, then the manufacturer's published overhaul or inspection schedule must be followed.

          
          

          To allow both the aircraft manufacturer and the FAA due opportunity to consider an extension request, requests should be initiated 50 flight hours or 30 calendar days prior to scheduled overhaul or inspection time, whenever feasible.

          
          

     2. Extension Request Procedures‌

  1. Extension Request

     An overhaul or inspection extension may be requested only by the Director of Maintenance or his designees.

     
     

  2. Request for Manufacturer’s Authorization

     If authorization is not stated in the Maintenance Manual or other existing documents; a copy of the Request stating Maritime Helicopters reason for the Request and expected means of accomplishing the maintenance being deferred, shall be e-mailed or faxed by the individual initiating the Request to the aircraft (airframe, engine, propeller, or appliance) manufacturer.

     
     

     A copy of the authorization (copy of page from Maintenance Manual or letter from Manufacturer) together with the Request is submitted by the initiator to the certificate holding office of the FAA.

     
     

  3. Request for FAA Approval

     Notification of the FAA is to be accomplished by signed dated request on company letterhead, letter sent electronically is acceptable. The FAA shall be explicitly requested to return e-mail request with written approval of the Extension Request. The DOM will contact the FAA with the e-mail Request.

     
     

  4. Approval Granted

     Upon FAA review of the Extension Request the appropriate FAA Principal Inspector (Maintenance or Avionics) will return the e--mail request either approved or disapproved. The Director of Maintenance (or his designee) will be responsible for implementation of Extension if approved.

     
     

     Once an applicable component reaches its normally scheduled TBO or inspection and an extension has been approved for that overhaul or inspection schedule, the mechanic maintaining that aircraft shall make a maintenance record entry containing the following information:

     
     

     Current date and aircraft (airframe, engine, or appliance) total time,

     
     

     Statement of discrepancy (i.e. specific component due overhaul or specific inspection due), Statement of maintenance/corrective action:

     
     

     “Scheduled overhaul/inspection interval extended in accordance with manufacturer's authorization and FAA- extension approval.”

     
     

     Revised Date and/or aircraft (airframe, engine, propeller, appliance) total time at which overhaul/inspection is now due,

     
     

     Mechanic's signature, certificate type and number.

     
     

  5. Service Difficulties

     During the period of extension, if any unusual circumstances or service difficulties with a component on overhaul or inspection extension are encountered, the mechanic maintaining the aircraft shall immediately notify Director of Maintenance. The Director of Maintenance (or his designee) shall contact the manufacturer and obtain the manufacturer's recommended disposition. The Director of Maintenance (or his designee) shall contact the FAA by the close of the next business day to inform the FAA of the service difficulty and to obtain FAA concurrence with the manufacturer's recommended disposition.

     
     

     For continued operation, the manufacturer's recommended disposition (inspection or maintenance) must be approved by the FAA and accomplished on the aircraft. Manufacturer's instructions should be obtained in writing. A maintenance record entry stating compliance with manufacturer's instructions will be required. In addition, other FAA documentation may be required (§135.415/135.417 report). The FAA shall be informed of action taken by the close of the next business day.

     
     

  6. Transfer of Extended Components

     The use of an extended component on an aircraft or assembly other than the one for which the extension was granted will require separate approval by the manufacturer and concurrence by the FAA.

     
     

     A mechanic undertaking such maintenance will first contact the Director of Maintenance. The Director of Maintenance (or his designee) shall contact the manufacturer and the FAA in order to ensure their concurrence with this transfer.

     
     

  7. Termination of Extension

     When an overhaul or inspection comes due at the end of its extended interval, the mechanic maintaining the particular aircraft will make a maintenance record entry documenting removal of affected component or completion of inspection and reference the extension. The mechanic will also notify the Director of Maintenance (or his designee) will inform the FAA within 7 days by telephone, fax, or e-mail that the extension has terminated. The Director of Maintenance will annotate the date and manner of contact with the FAA to close out the extension paperwork.

     
     

  8. Extension Record Keeping

     Expired Extension Requests will be filed by the Director of Maintenance for a period of two years following expiration of the extension.

     
     

     Current (open) Extension Requests will be kept by the Director of Maintenance throughout the duration of the extension and a copy will be available for review. The Director of Maintenance will update the certificate holding office of the FAA on current status of open extensions at 60-day intervals by email if needed.

     
     

     Sample Logbook Entries:

     
     

     NOTE: An entry will be required in the airframe logbook and in the appropriate engine logbook

  1. Maintenance and Mechanical Discrepancies‌

     Scheduled/Routine Maintenance and Mechanical discrepancies are entered in the Helicopter Log by an appropriately rated pilot or mechanic who discovers the discrepancy or prior to starting any Scheduled/Routine Maintenance. However, if a discrepancy occurs, a mechanic shall be notified as soon as practical (§135.23 (f) & §135.65 (a) (b)).

     
     

     When a discrepancy is entered in the Helicopter Log it must be addressed and signed off by a certified A&P mechanic or an FAA certified repair station holding the proper rating, or properly deferred in accordance with an

     
     

     approved MEL. (CFR §91.407, §135.23(e) & §135.65(a)(c)). The pilot shall ensure that work performed is properly signed off in the Helicopter Log and/or Deferred Maintenance Log (if applicable). (See mechanic's duties) (§135.23 (i)) Any time an aircraft is out of service for more than 24 hours, the Director of Maintenance will notify the Director of Operations. If the out of service occurrence happens after normal business hours and no assistance is required, the notification is to be made at the beginning of business the next day.

     
     

     If maintenance is performed by a non-certificated person the certificated mechanic must personally observe the work being done to the extent necessary to ensure it is being properly done and the company mechanic must be readily available, in person, for consultation. Print the name (not signature) of the non-certificated personnel in the appropriate corrective action statement of the maintenance record (§43.3 (d)).

     
     

     If a ground run or in-flight check is required following maintenance, that requirement must be entered in the Helicopter Log by the mechanic. The ground run or in- flight check must be satisfactorily completed prior to releasing the aircraft for any flight under CFR 135, and signed off by the pilot or mechanic, as appropriate. For specific guidance, refer to, Maintenance Operational Check (MOC) procedures.

     
     

  2. Maintenance Operation Check [§91.407]‌

     No one may operate any aircraft that has undergone maintenance, preventative maintenance, rebuilding or alteration unless:

• It has been approved for return to service by a certified A&P mechanic or an FAA certified Repair Station holding the proper rating; and

• The maintenance record entry required by CFR Part 43.9 (Content, form, and disposition of maintenance, preventative maintenance, rebuilding, and alteration record for inspections) has been made.

• No pilot may carry any person (other than required crew members) in an aircraft that has been maintained, rebuilt, or altered in a manner that may appreciably have changed its flight characteristics or substantially affected its operation in flight, until a maintenance operational check flight is conducted only by designated pilots in command (who have current CFR Part 135.293 (a)(b) check in the make and model aircraft requiring the MOC or a pilot approved by the company) and logs the flight in the aircraft records.

  
  

  Maintenance operational check flight will be accomplished any time it is required by the manufacturer or by regulation.

  
  

  Maintenance operation check-flights will be conducted only in VFR conditions with the ceiling and visibility at or greater than 800’/1/2 mile.

  
  

  The aircraft does not have to be flown as required in the above paragraph if prior to flight, ground tests, inspections, or both show conclusively that the maintenance, preventative maintenance, rebuilding or alteration has not appreciably changed the flight characteristics or substantially affected the flight operation of the aircraft (ref. CFR Part 91.407 (C) ).

  
  

  NOTE: A MOC must be entered in the log book as a separate entry and shall be written in a manner that clearly defines all the steps required for that particular MOC. The mechanic will assist the pilot in locating any pertinent information in the maintenance manuals that will be needed when performing a MOC.

  
  

  1. Major Alterations and Repairs‌

     No aircraft shall have any modification performed without proper documentation in accordance with the applicable Federal Aviation Regulations and Maritime Helicopters Policy. All data that is used to carry out Major Alterations and Major Repairs needs to be FAA approved; AC 43-210 contains guidance regarding this issue along with 14 CFR Part 43 Appendix A.

     
     

     Prior to any maintenance being started, you shall work with your local FSDO in developing a FAA Form 337 which needs block 8 (Description of Work Accomplished) reviewed to determine if block 3 needs to be signed by the local FSDO, either approving the data provided or field approving the alteration performed. If the local FSDO will not sign

     
     

     block 3 or indicates it doesn’t need to be signed, then within the guidance of AC 43-210, that FSDO needs to supply a written statement of why they don’t need to sign block 3,.see page 10 paragraph 302 b.

     
     

     Upon completion of any major alteration/repair requiring a 337, the Form will be provided to the following:

     
     

     • The FAA Aircraft Registration Branch, AFS-750, PO Box 25504, Oklahoma City, OK 73125. This must be a signed copy. Keep a standard scanned copy with the aircraft records at the base.

     • Logbook entries for major repairs or alterations will include the interval and next due time for any ICA (Instructions for Continued Airworthiness) information included on the 337 or manufacture repair procedure. Repair procedures will be attached to the 337 if applicable. Major repairs completed and signed of by a repair station on a work order may not require a 337 in which case the repair procedure will be attached to the logbook page and if applicable future inspection requirement due times will be listed.

       
       

  2. Mechanical Interruption Summary Report [§135.417]‌

     Mechanical Interruption Summery Reports shall be submitted to the Anchorage CHDO by the 10th day of the following month for each occurrence that is not required to be reported under §135.415 to include the following:

• Interruption to a flight

• Unscheduled change of an aircraft en route not weather related

• Unscheduled stops or diversion from en route due to known or suspected mechanical difficulties/malfunctions.

  
  

  1. Minimum Equipment List (MEL)‌

  1. Minimum Equipment List‌

     Minimum Equipment List, or MEL, is a means to permit continued operation of an aircraft with inoperative items of equipment or systems until repairs can be accomplished. The MEL list is developed from the Master MEL by the Director of Maintenance and Chief Pilot in cooperation with the FAA Flight Standards District Office. Each aircraft shall be issued a Minimum Equipment List for that particular type aircraft.

     
     

     The MEL lists the items of equipment, the number installed, the number required, under what conditions operations may continue, the deactivation procedure, how to placard, the maintenance procedure required, and the operating limitations affected by the deactivation. All equipment related to the airworthiness and the operating regulations of the aircraft not listed on the MEL must be operative.

     
     

     Complete MEL instructions, definitions, and procedures are explained in each individual type Minimum Equipment List issued to each aircraft.

     
     

     The MEL discrepancy list is located in the front of the logbook. Items on the approved aircraft MEL may be transferred to this list from the logbook sheet. The logbook entry shall refer to the transfer. The date the MEL item is due correction shall be carried on the MEL discrepancy list located in the front of the log book. The mechanic making these entries shall communicate to the Chief Inspector the discrepancy via email within 24 hours.

     
     

     The Chief Inspector oversees the MEL Management Program. A copy of each aircrafts MEL may be found in Appendix B.

     
     

  2. Nonessential Equipment and Furnishings‌

  Nonessential equipment and furnishings (NEF) are those items installed on the aircraft as part of the original certification, supplemental type certificate, or engineering order that have no effect on the safe operation of flight and would not be required by the applicable certification rules or operational rules. They are those items that if inoperative, damaged or missing have no effect on the aircraft’s ability to be operated safely under all operational conditions. These nonessential items may be installed in areas including, but not limited to, the passenger compartment, flight deck area, service areas, cargo areas, crew rest areas, lavatories, and galley areas. NEF items are items not already identified in the MEL of the applicable aircraft and do not include items that are functionally required to meet the certification rule or for compliance with any operational rule.

  
  

  These NEF items may be entered in the logbook by flight crew members and maintenance personnel. By maintaining them on the Deferred Discrepancy Sheet(s) in the front of the Flight and Maintenance Log, they can be scheduled with routine inspections for efficient and effective correction. The description, re-inspect or time limit imposed (if any) and date of the deferral will be listed.

  
  

  Any item found to be inoperative, damaged or missing that is not listed here and believed to have no effect on the aircraft’s ability to be operated safely under all operating conditions which appears to be an NEF item shall be brought to the attention of the Director of Maintenance and the Chief Pilot. A determination as to the proper classification of the item for deferral will be made and the item will be entered on the NEF listing.

  
  

  The NEF procedures for Flight and Maintenance Log entries will be the same as the MEL. A copy of NEF Program may be found in Appendix B.

  
  

  1. Missing or Mutilated Certificates [CFR 47.49, FAA Order 8130.2 as revised]‌

     If the aircraft airworthiness certificate or registration certificate is missing or mutilated beyond recognition proceed as follows:

     
     

     1. Aircraft Airworthiness Certificate‌

        Notify the Director of Maintenance. The Director of Maintenance will notify the local FAA, requesting the aircraft airworthiness certificate be reissued.

        
        

     2. Registration Certificate‌

        Notify the Director of Maintenance immediately, the Director will contact the FAA.

        
        

  2. Outside Vendor Maintenance‌

     Any vendor or contractor must be approved and listed on Maritime Helicopters Approved Vendor list prior to performing maintenance on a Maritime Helicopters’ aircraft. Kept on file in Maintenance Office.

     
     

     The Maritime Helicopters Individual managing large projects will review the work performed and ensure records and log book entries are sent to Maritime Helicopters Maintenance Department for review. FAA Form 337’s will be reviewed by the Maintenance Department. These records will be reviewed and a new Status Sheet will be sent to the Vender to verify all items are completed and no maintenance is due prior to releasing the aircraft from the Vendor.

     
     

     The duty mechanic or a company A & P mechanic will inspect all maintenance performed by an outside vendor as soon as the aircraft returns to determine that such work is satisfactory and the necessary log book entries are made. To include, if the aircraft comes back from major maintenance and/or refurbishment, the mechanic reviewing all paperwork, log book entries, and 337’s to ensure no additional ICA inspection items are required. If any “additional” inspection requirements are generated by a modification, the mechanic will verify that this requirement has been entered in the applicable computerized tracking system (CALM) for compliance.

     
     

  3. Parts and Component Control‌

     1. Parts Handling‌

        Damaged or suspected unapproved parts shall be returned to the Maritime Helicopters 145 Repair Station and the Inventory Administrator, Director of Maintenance, and Chief Inspector will be notified.

        
        

        All spare parts and components shall be preserved in accordance with the manufacturer’s recommendations or standard procedures. The procedures used will be methods appropriate to the parts or units to assure protection until the part or unit is placed into service.

        
        

        All parts removed from service must be preserved in the same manner in order to prevent corrosion damage during shipment and meet shipping requirements.

        
        

        All parts shipped to or from a field location are packaged, boxed, or placed on stands, as necessary, to prevent shipping damage or damage from the elements.

        
        

        All parts received at a field location will be inspected by the technician at that location. The technician will inspect the part to ensure the part was packaged correctly and was not damaged during shipment. The technician will ensure the part number and serial number match up with the documentation that came with the part.

        
        

        All documentation and paperwork that came with a part will be sent to the Records Department along with the appropriate log page after installation. All parts shipped from a field location will have all required documentation completed.

        
        

     2. Material Safety Data Sheets‌

        Parts or consumable items containing hazardous materials will be packaged accordingly. “Safety Data Sheets are available via Maritime’s subscription to 3E Company online;

        
        

        https://www.3eonline.com/eeeOnlinePortal/DesktopDefault.aspx

        
        

        Contact the Quality and Safety Manager for Password and Usernames for site. The alternate method for accessing Maritime’s SDS Database (or any SDS in an emergency)is by contacting 3E at 1-800-451-8346.

        
        

     3. Component Shelf Life‌

        Items and materials will be tagged to show date of un-serviceability. Shelf life of aircraft items is determined by the manufacturer. If no day is included in the expiration date, it is the last day of the month shown. Stock of shelf life limited items shall be stored in the environment recommended by the manufacturer and current practices of the aviation industry. Aircraft items which exceed shelf life shall be removed from stock.

        
        

     4. Component Inventory Rotation‌

        The parts department will ensure stored serviceable items with the greatest accumulated shelf time are put into service first. The first received items, based on the date on the receiving inspection tag or manufacturer’s expiration date, are to be the first items used. Examples of these are O-Rings.

        
        

     5. Parts Tagging‌

  In accordance with FAA Regulations, all parts must be properly tagged.

  2.25.5.1 Removal

  Determine if the part is Serviceable, Unserviceable or Repairable. Using the appropriate tag, complete all areas of the tag which may be used for warranty purposes. All parts must have their own tag; a single tag may not be used for multiple parts.

  
  

  Examples of serviceable as removed reasons may be; troubleshooting, needed on other aircraft, rental etc. If not serviceable:

  
  

  Record applicable details in the “reason for removal area.” Inappropriately marked repairable or unserviceable tags with terms like “wobbles”, “worn-out”, “loose”, “leaks”, “INOP”, etc. do not give an accurate description of the damage, nor do they indicate why a part was rejected.

  
  

  In order to determine if a part is beyond limits it is necessary to know what the limit is. Published limits are available from manufacturers through maintenance manuals, overhaul manuals, bulletins, standard practices manuals, repair manuals, and other reference material. Once it has been determined that a part is out of published limits it is necessary to include that information on the tag that accompanies the part if repairable.

  
  

  Also, it is necessary to include the measurement or criteria that rendered the part out of limits as well as “Worn beyond acceptable limits” or a similarly worded statement.

  
  

  Also include in the reason for removal any comments such as “warranty” or any details that may be helpful in evaluating warranty consideration or if the part is involved in an insurance claim.

  
  

  In accordance with FAA Regulations, all parts must be properly tagged.

  
  

  2.25.6 Types of Component Tag‌

  1. Yellow Tag

     The Yellow Tag, or Serviceable Tag, is used to identify items that are in an airworthy condition and are ready for return to service. The maintenance release on the back of the tag must be completed including work order number, if any, date, inspector signature and/or stamp, and what type of work that was performed.

     
     

     Yellow tags have an installation information section which should be filled out by the technician installing the item on an aircraft. A technician may install a yellow tag on a part that has been repaired, overhauled, inspected, functionally tested, or removed in an airworthy condition.

     
     

     The technician installing the item on an aircraft will attach the yellow tag to the back of the appropriate logbook page. This tag becomes part of the aircraft records.

     
     

  2. Green Tag

     The Green Tag, or Repairable Tag, is used to identify items that are repairable or require serviceability evaluation. These tags must be filled out completely and accurately. The green tag is disposed of by the technician when the item is ready for return to service.

     
     

  3. Red Tag

  The Red Tag, or Unserviceable Tag, is used to identify items that are not airworthy and not repairable. This tag must not be removed until the item is destroyed. The red tag requires two signatures, one technician signature and one inspector signature after final inspection. The technician attaching a red tag to an item must return the item to the Chief Inspector for final determination.

  
  

  Segregation shall be strictly adhered to between red tagged and yellow or green tagged components. A separate storage area will be designated and all red tagged components placed there until item is destroyed.

  
  

  

  2.25.7 Parts Vendors‌

  
  

  All parts vendors shall be screened by a MHI maintenance supervisor who holds the minimum of an A&P. At a minimum this will include a search of their web presence and if needed, phone calls to them and other operators that have worked with them.

  
  

  The results will be tracked in our current C.A.L.M. system. Inventory personnel shall note if any vendor they are going to order from has been approved thru CALM annotated by a checkmark in the approved vendors list. If no checkmark noted, they shall enquire and a vendor review shall be initiated by a qualified MHI maintenance manager.

  
  

  1. Service Bulletin Guidance‌

     Mechanics will be notified of Service Bulletins (SB’s) that Maritime Helicopters Director of Maintenance chooses to comply with. Each aircraft and engine has a publication subscription with the manufacture and SB’s will be sent direct to the base of record from the manufacture.

     
     

     

     
     

     Service Bulletins will always be addressed in the aircraft log book either by compliance or the statement “Maritime Helicopters elects not to comply with this Service Bulletin at this time. The status sheet will then be updated when the Mechanic makes a logbook entry indicating it was complied with, when it is due, it is not applicable or other information as appropriate.

     
     

  2. Service Difficulty Reports [§135.415]‌

     Pilots will inform the Director of Maintenance of the occurrence or detection of each failure, malfunction, or defect in an aircraft listed in §135.415(a). The report must be made submitted by hard copy or email and be completed within 24 hours of the occurrence. The report must contain a detailed description and requirements of §135.415(e).

     
     

  3. Shelf Life‌

     Items having a shelf life shall be monitored by the base mechanic, on a monthly basis, utilizing the Maritime Helicopters’ Shelf Life Audit checklist. Any items, other than components or parts, exceeding their shelf life shall be removed from serviceable stock and disposed of properly. Components or parts that have exceeded allowable shelf life will be tagged “rejected” and placed in a Maritime Helicopters’ designated quarantine area for final disposition. A shelf life audit of consumables such as Proseal, grease and lubricates shall be performed each month on a set date and the results recorded on the shelf life audit form.

     
     

     A copy of the shelf life audit form may be found in Appendix A.

     
     

  4. Tool Calibration‌

     All precision tools that are used to hold a standard, and/or that are used for acceptance for return to service, shall be calibrated every 365 days or in accordance with the manufacturer’s recommendations (which may exceed 365 days). All tools shall have a label that will identify the unit by serial number or identification number and next calibration due date. Original certifications shall be kept at the base. Prior to using a calibrated tool, it must be confirmed to be current.

     
     

     All tools will be tracked showing next compliance due by the following method;

     
     

• The Director of Maintenance or designee will enter the tool information on to the 135 Tool Calibration list.

• The Chief Inspector or designee will review the list monthly and notify the appropriate individual of tools requiring calibration.

  •

  
  

  1. Transponder, Altimeter and Altitude Reporting Inspections [§91.411, §91.413]‌

  Whenever a pitot static system is opened for reasons of repair, inspection, etc, the system will be inspected and tested. Following installation or maintenance of the static system, transponder or altimeters where data correspondence error could be introduced, the integrated system must be inspected and tested.

  
  

  These tests must be performed by an appropriately rated repair station. The repair station must complete a log book entry in the Maritime Helicopters Helicopter Log Book prior to the next flight.

  
  

  2.31 Weight and Balance [§135.23, §135.185, §135.63(c)]‌

  Each multi-engine aircraft shall be weighed at least every 36 calendar months. Single engine aircraft shall be weighed every 12 months to meet OAS requirements. Weighing will be accomplished only by Maritime Helicopters or a provider of services approved by the Director of Maintenance. A Maritime Helicopters’ mechanic will be present when the aircraft is weighed. Prior to weighing, the mechanic shall ensure that the scales have been calibrated within the previous 12 months. An entry will be made in the Aircraft Log Book noting the make, model, serial number, and

  
  

  calibration date of the scales. All aircraft should be weighed in accordance with the manufacturer’s maintenance manual. Updated weight and balance and equipment list shall be inserted into the Rotorcraft Flight Manual.

  
  

  1. Major Alterations including Aerial filming Equipment‌

     On occasion, Maritime Helicopters is chartered to perform aerial filming. For this type of installation, or any and all installations properly certificated company mechanic(s) shall use the following checklist for proper compliance, the Chief Inspector will be responsible for;

     
     

• Verify that the STC kit is complete.

• For aerial filming installations, verify that STC approved installation data for the mounts are for the actual type of camera to be installed. If there is no STC approved installation data, the equipment shall not be installed.

• Verify that STC approved installation data for the actual equipment to be installed. If there is no STC approved installation data, the equipment shall not be installed.

           • Complete corrective actions and required documentation for all other items on log page.

           • Close the log page.

           • Initiate next log page as normal.

           
           

           Note: If the engine is not loaded in the CALM or a new status sheet did not get printed for the engine, the CALM report for the removed engine will be updated by pen and ink with the installed engine information. All inspections and the next component due will be determined and updated prior to return to service.

           
           

     3. Records Locations‌

        The Helicopter Log Book, the Aircraft Status CALM Report and the current Deferred Maintenance Log shall remain in the aircraft whenever it is flown. When an aircraft is transferred, the current Deferred Maintenance Log and the updated Aircraft Log Book will remain with the aircraft and constitute the current status for that aircraft (§135.23 &

        §135.65 (a)).

        
        

        All other maintenance documents will either reside in Homer or Fairbanks depending on where the aircraft is stationed. All maintenance paperwork will remain on file until the inspection is repeated to include CAMP and/or AAIP inspections.

        
        

     4. Record Entry Requirements [§135.443]‌

        Each person who maintains, performs preventative maintenance, rebuilds or alters an aircraft, aircraft engine, propeller, appliance, or component part shall make an entry in the maintenance record of that component [in the event of engine maintenance, an entry will also be placed in the airframe log book]. An appropriate certificated mechanic or Repair Station shall provide an airworthiness release. The appropriate maintenance entry will contain the following information (ref. CFR Part 43.9).

  The next due block on the helicopter log should only be used for non-routine items (tq checks, MEL due, and other one off tracking). All the scheduled next due inspections are on the CALM and shall not be entered on the helicopter log. This procedure helps prevent a next due time of a scheduled inspection getting carried forward incorrectly.

  
  

  A copy of the Helicopter Log may be found in Appendix A.

  
  

  1. Logbook Transfer Statement‌

     When closing out a logbook Maritime Helicopters Inc. requires a logbook entry to be made on the last page of the logbook and the first page of the new logbook stating that all pertinent information has been transferred to the new logbook. For any questions please contact the maintenance department.

     
     

  2. Aircraft Compliance Action Notice‌

     A Compliance Action Notice, or CAN, is Maritime Helicopters Inc.'s method of ensuring action is taken in a timely manner. It may be in reference to an Airworthiness Directive, a Manufacture's Bulletin or whenever the Director of Maintenance or Chief Inspector finds it necessary to ensure compliance with an issue.

     
     

     The publication referenced shall be attached to the Compliance Action Notice. The mechanic performing the task shall make the appropriate entry in the log book and return the Compliance Action Notice to the records department to be filed.

     
     

     If parts are required, the Director of Maintenance or Chief Inspector shall send the Compliance Action Notice to the Parts department first so that the parts needed to accomplish the task may be acquired. The Parts Manager shall notify the Director of Maintenance or Chief Inspector when the parts are in, so maintenance personnel can accomplish the task.

     
     

     The Compliance Action Notice number shall be the last two digits of the current year followed by the sequential number of the issued CAN. This reference number will be in the upper right portion of the form. Issuing date, due date, and whether it is a one-time action or a recurring action will also be on the upper portion of the form.

     The registration numbers of all aircraft affected by that particular CAN will be listed.

     
     

     The reason for the CAN will be listed by bulletin number or other brief description. The affected part and affected part numbers will be listed if applicable. The “COMMENTS” section will have basic instructions listed, as well as whether or not this action requires a logbook entry.

     
     

     The lower portion of the Compliance Action Notice has information necessary for recordkeeping and tracking. The registration number and serial number will be printed on this section of the CAN. The aircraft total time at completion and, if recurring, time next due will be filled in by the technician.

     
     

     The method of compliance section shall state the wording of the logbook entry or describe the method of compliance with enough detail to ensure understanding. A signature and date must be included, and either a certificate type and number or an employee identification number must be entered on the lower portion of the CAN.

     The completed Compliance Action Notice shall be returned to the Maintenance Records Department as soon as possible after completion, on or before the due date. The Maintenance Records Department shall enter required information on historical records, airworthiness directive and bulletin lists as needed.

     
     

     The Compliance Action Notice Completion Sheet provides means to ascertain status of CAN's and provide additional information necessary to the Records Department.

     
     

     The form includes the CAN number, the issue and due date, and the subject along with method of compliance. The form also includes a section to inform whether a logbook entry is required.

     When the Compliance Action Notice is returned to the Records Department, the date and aircraft total time are recorded on this form, and the name and identifying number of the technician responsible is also recorded.

     
     

     A copy of the Compliance Action Notice may be found in Appendix A.

     
     

  3. Engine Trend Charts‌

     The trend check analysis provides a method for the Maritime Helicopters to monitor engine health. Tracking the daily power checks on each engine over an extended period of time will help provide a good picture of the engine overall heath and performance.

     
     

     Engine trend charts shall be kept in the aircraft log book with the aircraft make, N number, engine S/N, and current month entered at the top of the form. At the end of the flight day the pilot shall plot the power check result on the engine trend chart. At the end of the month the charts will be pulled and sent to the aircrafts base to go with the engine records and a new chart will be started for the next month.

     
     

     A copy of the Engine Trend Chart may be found in Appendix A.

     
     

  4. Submission of Maintenance Records‌

     1. Maintenance times Submission Policy - On Base‌

        1. Procedures

           Either the mechanic or pilot will submit the current day’s Log Pages using email to actimes@maritimehelicopters.com by the end of their shift daily. If the aircraft is on a contract with only the pilot, then the pilot will submit current day’s log page.

           
           

           

           Have any inspections been performed today?

           
           

           If no flight time and no inspections, send message to actimes email saying: “No

           Has the aircraft flown today?

           Yes

           No flights on (insert date here).”

           Yes No

           
           

           Are inspections properly signed off?

           
           

           Are the pilot’s calculated ending times correct for each column?

           
           

           Yes No

           
           

           
           

           Verify that inspection has been performed. If it has, mechanic who performed the inspection must sign off on it.

           
           

           Yes

           
           

           No

           
           

           Create a write- up for your correction and correct the times at top of log page.

           
           

           The log page is now ready to be submitted to Maintenance.

           
           

        2. Correcting Maintenance times

           If times are incorrect, the pilot or mechanic closing out the log page must find the arithmetic error and make a correction. Math must be verified using a calculator. Calculators are in Pilot Fly Away Kits and are always available on base.

           
           

           • Initial next to your correction

           • Write legibly!

           
           

           3.8.1.2 Submitting Maintenance Times

           Maintenance times while the helicopter is on-base may be submitted one of three ways:

           
           

           1. Maintenance times and all performed inspections can be emailed to actimes@maritimehelicopters.com. Scans or clear photos of log pages are preferred. Photos must include all times and sign-offs. Take multiple pictures if all the information cannot be fit into one!

           2. Yellow carbon copies of closed log pages shall be removed from the log book and hand-delivered to the Maintenance if in Homer or Fairbanks. All other bases must mail in yellow sheets as soon as a week’s worth of records are accumulated.

           3. Maintenance may go to the aircraft cans and remove the yellow carbon copies before the end of his or her shift, provided they are ready to be removed. If they are not ready to be removed from the log book, Maintenance may record all relevant times on a notepad, Post-It, etc. to be transferred to CALM.

           
           

     2. Maintenance Times Submission Policy - In Field‌

        Due to the unreliable nature of Internet and phone services in remote parts of Alaska, pilots and mechanics out in the field may find it difficult submitting times. Picture/Scans or log book pages are to be taken daily and if the pilot stops at an area where this is internet/phone service access, they should make an effort to transmit the stored pages. Additionally, pilots and/or mechanics leaving for a field job should meet with the maintenance personnel at their base of operation before leaving to determine what options may be available to them for maintenance time submission.

        
        

        Factors to take into consideration when determining the best way to submit times from the field include:

        
        

        • How long is the aircraft expected to be in the field?

        • How many hours is it expected to fly?

        • Will customer-provided equipment be available for use? For example, land line telephone, satellite phones or wireless internet access.

          
          

  5. Record Keeping Requirements‌

     The record keeping requirements of CFR 91.417 will be complied with in the following manner. The following items will be mailed to Maintenance on a weekly basis:

     
     

     • The yellow sheet of the Aircraft Log Book.

     • A copy of any entries made in the engine log book (or the original engine log book page when it is filled full).

     • Original versions of all maintenance release forms.

       
       

       The Director of Maintenance or a designated representative will ensure that a current CALM Status Reports are posted weekly to the Maritime Helicopters Maintenance Portal and contain the following sections:

     • Items Due.

     • Airframe Components / Inspections.

     • Airframe Bulletins.

     • Airframe ADs.

     • # 1 Engine Components / Inspections.

       
       

• # 1 Engine Bulletins.

• # 1 Engine ADs.

• # 2 Engine Components / Inspections.

• # 2 Engine Bulletin.

• # 2 Engine ADs.

  
  

  These sections contain a listing of the following records:

  
  

• The total time in service of the airframe, each engine, each propeller, and each rotor.

• The current status of life-limited parts of each airframe, engine, propeller, rotor and appliance.

• The current status of overhauled items installed on the aircraft which are required to be overhauled on a specific time basis.

• The current inspection status of the aircraft, including the time since the last inspection required by the inspection program under which the aircraft and its appliances are maintained.

• The current status of applicable airworthiness directives (AD) including, for each, the method of compliance, the AD number, and the revision date. If the AD involves recurring action, the time and date when the next action is required.

These listings will be used by the pilot and mechanic to determine the airworthiness of the aircraft and to schedule maintenance. None of the above listings is considered part of the permanent aircraft record. The Aircraft CALM Status Reports listed above shall be compared to the new copies to verify that all changes made are valid. Once the new copies are verified (or corrected by direct consultation with maintenance personnel), the old forms may be disposed of.

Records of the maintenance, preventative maintenance, and records of the 100-Hour, CAMP and other required or approved inspections, as appropriate, for each aircraft (including the airframe) and each engine, rotor, and appliance of an aircraft will be retained at a minimum until the work is repeated or superseded by other work or for one (1) year after the work is performed (§91.417 (b) & §135.65 (d)).

Records containing total time in service and/or current status of life limited part and/or time since overhaul of each airframe, engine, propeller, and rotor as well as the current inspection status of the aircraft, will be retained and transferred with the aircraft at the time the aircraft is sold (§91.419 (a)).

Records containing the current status of applicable Airworthiness Directives (AD) including, for each, the method of compliance, the AD number, and revision date, and, transferred with the aircraft or the time the aircraft is sold (§91.417(b)). Maintenance records will be available for inspection by the FAA or authorized representative of the NTSB.

Operations Specification are maintained in an Appendix of MHI GOM and carried onboard each aircraft.

1. PUBLICATIONS‌

   
   

   1. Changing Publications Media‌

      Aircraft are assigned either paper or CD ROM when the aircraft comes from the vendor. They are tracked that way until the publications are changed.

      
      

      To change the media of an aircraft, approval is needed from the Director of Maintenance. All publications are tracked items as stated above, it is important that Director of Maintenance is aware of what the base is using for all publications.

      
      

   2. Maintenance Manual Revisions‌

      Maritime Helicopters’ will receive revisions for their applicable maintenance manuals from the manufacturer. The Maritime Helicopters’ shall notify each base of the new revision.

      
      

      The Maritime Helicopters is responsible to provide the shop maintenance staff the most current publications issued by the OEM’s, to ensure 100% compliance with current maintenance manuals. Updated aircraft maintenance manuals are required to perform aircraft maintenance. However, when the OEM’s or other vendors publish a change, a time delay in the notification system will occur, so the aircraft OEM’s provide maintenance update pages, which will allow real time access to the aircraft manuals revision status.

      
      

      Maintenance staff will check the OEM’s web page monthly to ensure they have the most current publications on file. If a change has been posted to the OEM maintenance website and a mechanic has not received notifications from the Maritime Helicopters Parts and Pubs Coordinator, the mechanic will notify the Director of Maintenance as soon as possible.

      
      

      The Maritime Helicopters will audit the aircraft maintenance manuals, to be conducted around the end of the year.

      
      

   3. Instructions for Continued airworthiness (ICA)‌

      
      

      Instruction for Continued Airworthiness are accessed either directly online thru the appliance manufacturer or they may be obtained from the Maritime Maintenance Portal.

      
      

      NOTE: It is the mechanics responsibility to verity prior to any maintenance that the Portal ICA is the most current revision. Any ICA’s that are found revised should be brought to the attention of the Director of Maintenance who will then update the Maintenance Portal. If possible, download the new ICA and email a copy to the DOM.

      
      

2. MAINTENANCE PERSONNEL‌

   1. Distractions While Performing Maintenance‌

      Maritime Helicopters’ maintenance technicians are tasked with a myriad of responsibilities while performing aircraft maintenance. The requirements of daily operations, particularly time constraints, regulatory compliance, mission readiness, and fiscal concerns, can create distractions in maintenance routines and procedures. It is the maintenance technician’s responsibility to minimize distractions while performing maintenance on Maritime Helicopters’ aircraft.

      
      

      Manufacturers’ maintenance procedures and the Maritime Helicopters CAMP’s, shall be utilized to preclude missing a step for a given maintenance task. If a maintenance technician is interrupted during a maintenance procedure, the maintenance sequence will be reviewed three maintenance steps prior to where interruption occurred.

      
      

      The use of cellular phones while performing maintenance on Maritime Helicopters aircraft is prohibited. Incoming phone calls shall be directed to voice mail and may be retrieved upon completion of the task. Phone calls serve as a distraction and may cause the maintenance technician to miss a critical step during a maintenance procedure.

      
      

      Additional distractions such as personal issues, work relationships and health concerns should be resolved prior to performing aircraft maintenance. It is recommended that the maintenance technician contact his or her supervisor if issues exist that would serve as a distraction while performing aircraft maintenance.

      
      

   2. Experience and Training Statement‌

      Maritime Helicopters mechanics shall meet the minimum experience and training requirements set forth in the CFR’s. Field mechanics may decline, without fear of reprimand, performing any aircraft maintenance critical to flight safety for which he or she has not been properly trained or does not have adequate experience until an adequately trained or experienced mechanic can directly supervise or assist. (CFR §65.83, §135.435)

      
      

      1. Training Oversight‌

         The Maintenance Department has developed a Maintenance Training documentation tracking and auditing process that will ensure the maintenance training records are 100% compliant.

         
         

         All new hire mechanics or mechanics who have been out of the system for more than one year must attend the first scheduled Maritime Helicopters Initial Maintenance Training class. If unable to attend to the first scheduled class they may attend the next class available but may not exceed the second available class.

         
         

   3. Fatigue Risk Management‌

      The following section is intended to specify guidelines to ensure that Maritime Helicopters Mechanics have adequate rest to ensure optimum performance when on duty. In aviation maintenance, there are occasions when it is necessary to work long hours in order to maintain aircraft in an airworthy condition. It is expected that scheduled maintenance should be planned and accomplished without the need for long periods of extended work hours.

      
      

      If any mechanic becomes aware that fatigue and/or stress has made it impossible for him or her to continue to perform maintenance in accordance with the standards required for airworthiness, they will cease work and notify his or her immediate supervisor. Likewise, it is the obligation of any individual supervising aircraft mechanics, to monitor the effects of extended work hours and stress (as well as environmental factors) on mechanics performance.

      
      

      Personnel safety and aircraft airworthiness are our top priority.

      
      

      Mechanics assigned from Maritime Helicopters’ Homer base shall notify the Director of Maintenance that they are going to cease performing maintenance on the aircraft until a specific time. Mechanics in Fairbanks shall notify the Fairbanks Maintenance Lead.

      
      

      Mechanics are not authorized to have a workday that exceeds 8 hours without supervisor approval. Once approved, the workday may not exceed 12 hours. At the completion of a 12 hour workday, eight hours of rest are required prior to beginning another workday.

      
      

      Mechanics are not permitted to work more than 12 cumulative hours in a 24 hour period for example; if a mechanic works 10 hours from 7AM to 5PM then goes home and is called back in at 7PM, they may only work an additional 2 hours. This restriction may be waived by a maximum of 2 hours providing; the project can be completed, verbal approval from the Maintenance Director has been given, and safety is not compromised.

      
      

      Following extended maintenance of 12 to 14 continuous hours, it is recommended that a mechanic should be scheduled for an uninterrupted rest period of at least 8 hours. A mechanic should be relieved from duty for at least 24 consecutive hours following 10 consecutive extended duty days of 12 or more cumulative hours of actual aircraft maintenance activity in a 24 hour period.

      
      

      NOTE: This 12 hours, 10 consecutive days requirement is exclusive of “standby time” a field mechanic may experience while the aircraft is flying and only denotes hours where the mechanic is actually physically working on the aircraft.

      
      

      Mechanics and maintenance supervisors who arrive at work after prolonged travel must plan to arrive to allow 10 consecutive hours of rest. Prolonged travel is defined as 12 hours of more.

      
      

      In the event a mechanic or supervisor has to exceed 12 hours of aircraft maintenance, a report must be forwarded by the mechanic or his/her supervisor to the DOM who will record and track each exceedance event for the maintenance staff and supervisors. The report will include the mechanics/supervisors name, location, reason for the exceedance, and how many hours in excess of 12 were worked.

      
      

      Environmental conditions for the above guidelines are presumed to be normal; that is, the mechanic is working outside in good weather or is protected from the elements (i.e. in a hangar, “field shelter”, etc.). If the maintenance is taking place outside in very hot, cold or inclement weather, the duty times should be adjusted accordingly. Likewise, conditions inside a hangar, field shelter, etc. may require reduced duty times (temperature extremes, chemical exposure, noise exposure, etc.)

      
      

      All of the items listed above shall be adhered to and not be deviated from without prior approval from the maintenance department management.

      
      

   4. Foreign Object Damage (FOD) Prevention‌

      1. Objective‌

         The primary objective of Foreign Object Damage (FOD) Prevention is to establish procedural practices that will ensure a work environment free of extraneous material that might result in damage to aircraft. Additionally, following this program will assist in finding and correcting existing potential hazards and eliminating the causes of FOD. The Company is dedicated to providing its personnel with the training, procedures, practices and attitudinal sets in order to prevent costly damage to equipment and possible injury to personnel. Employees should read and become familiar with the FOD prevention.

         
         

      2. Definition‌

         FOD is damage to or malfunction of an aircraft caused by an object that is foreign to an area or system, or is ingested by or lodged in a mechanism of an aircraft. FOD may cause material damage, or it may cause equipment or a system to be unusable, unsafe or less efficient, as in the case of fuel contamination. Examples of FOD include ingestion into the engine of loose hardware, red rags, grass, flight controls jammed by hardware/tools, tires cut or debris-damaged rotors.

         
         

      3. Task‌

         Stress FOD prevention throughout the Company and provide adequate training for all personnel at all operating levels. Related tasks for all personnel include the following:

         1. Require a “Clean as You Go” Policy.

         2. Perform maintenance tasks according to technical publications data.

         3. Make sure aircraft openings, ports, lines, hoses and ducts are properly plugged or capped to keep foreign objects from entering critical aircraft areas.

         4. Make sure all tools, equipment and hardware are accounted for at the end of each maintenance task.

         5. Use care when performing tests and operating equipment.

         6. Participate in scheduled “FOD” ramp walks.

         7. Perform thorough preflight inspections and ensure cleanliness of the aircraft interior.

         8. Avoid hovering or flying aircraft at extremely low altitudes over sandy or loose gravel areas.

         9. Inspect all equipment before use, to make sure it will not cause FOD.

         10. Check engine inlet screens for loose or trapped objects (e.g. broken wire).

         11. As soon as possible, report any potential FOD to the appropriate supervisor if it cannot be corrected immediately.

         12. Keep all work areas clean and free of debris.

3. PARTS AND EQUIPMENT CONTROL‌

   1. Parts and Components‌

      For all maintenance, parts shall be procured through the Maritime Helicopters Inc. 145 Repair Station. Damaged or suspected unapproved parts shall be returned to the Maritime Helicopters Inc. 145 Repair Station and the Parts Manager, Director of Maintenance, and Chief Inspector will be notified.

      All spare parts and components shall be preserved in accordance with the manufacturer’s recommendations or standard procedures. The procedures used will be methods appropriate to the parts or units to assure protection until the part or unit is placed into service.

      Parts or consumable items containing hazardous materials will be packaged accordingly. Material Safety Data Sheets are available as required in the main Fairbanks hangar and also as needed at all other locations.

      All parts removed from service must be preserved in the same manner in order to prevent corrosion damage during shipment and meet shipping requirements.

      All parts shipped to or from a field location are packaged, boxed, or placed on stands, as necessary, to prevent shipping damage or damage from the elements.

      All parts received at a field location will be inspected by the technician at that location. The technician will inspect the part to ensure the part was packaged correctly and was not damaged during shipment. The technician will ensure the part number and serial number match up with the documentation that came with the part.

      All documentation and paperwork that came with a part will be sent to the Records Department along with the appropriate log page after installation. All parts shipped from a field location will have all required documentation completed.

      
      

   2. Parts Request Policy‌

      1. Procedures‌

         Parts Requisition Forms may be filled out by mechanics or the Inventory Manager and must be completed for all parts or consumable items to be ordered. All parts requests must be approved by either the Director of Maintenance or the Director of Operations.

         1. When to Create a Parts Requisition Form

            • When stock of an item is low or insufficient for upcoming maintenance needs.

            • When a part needs to be special-ordered for maintenance purposes.

            
            

         2. How to Fill Out a Parts Requisition Form

            1. Confirm accuracy of part number. If you have an alternate number available, make note of that as well.

            2. Use manufacturer nomenclature to describe part, whenever possible.

            3. Note the tail number for which this part is being ordered, if applicable.

            4. If ordering parts that will be split between a specific tail number and stock, enter them on separate lines.

            5. When writing down the reason, try to be specific. For example, “worn beyond limits” is better than “broken”.

            6. Select a priority!

            
            

      2. Submission Procedures‌

         
         

         Homer

         1. Once form is filled out, mechanic should hand-carry it to the Inventory Manager. In turn, the Inventory Manager will get with either the Director of Maintenance or Director of Operations for approval.

         2. After parts request is approved the Inventory Manager will fill order.

         
         

         Everywhere Else

         1. If Internet access is available, requesting mechanic may complete a fillable PDF version of the Parts Requisition Form and email it to mhiparts@maritimehelicopters.com. This distribution email will automatically be sent to both the Director of Maintenance and Director of Operations.

         2. If Internet is unavailable, requesting mechanic should call the Homer office and place their Parts Request over the phone with the Inventory Manager who will then complete a paper Parts Requisition Form.

         1. Fairbanks Ordering Procedures

            • A Parts Requisition Form must have been created and submitted to the Fairbanks Maintenance Lead, Director of Maintenance or Director of Operations for approval.

            • After approval, the Fairbanks Inventory Manager may begin searching for the required part(s).

            • Once the part(s) have been found and vendors have provided quotes, those quotes must also be submitted to the Fairbanks Maintenance Lead (orders under $1000) or Director of Operations (orders over $1000) for a second approval.

            • After the quote is approved, the Fairbanks Inventory Manager will generate a Purchase Order (PO). The Fairbanks Inventory Manager must give this PO number to the vendor when ordering their parts.

            • Packing lists and other paperwork not related to serviceability must be mailed to Homer every Friday for processing.

            
            

      3. Purchasing Policy‌

         These procedures assume that a mechanic has already followed the proper procedure for submitting a parts request outlined previously. If the parts request is for Homer, Kenai, Kodiak, or Akutan-based aircraft or inventories, the part will be located and ordered by the Homer Inventory Manager.

         
         

         If the parts request is for Fairbanks or any one of the Alyeska Pump Stations, the part will be located and ordered by the Fairbanks Inventory Manager. Packing lists and other paperwork not related to serviceability must be mailed to Homer every Friday for processing.

         
         

         

   3. Precision Measuring and Test Equipment‌

      Test and measurement equipment is checked for accuracy at periodic intervals established by usage, purpose, and stability of the equipment or the manufacturer’s requirements. The Chief Inspector maintains calibration data about

      m. equipment. The individual technician’s personal test and measurement equipment has the same accuracy check requirements as Maritime Helicopters equipment.

      
      

      The Inspection Department shall maintain information about Maritime Helicopters and personal test equipment. Leased or rented equipment shall be inspected by the Inventory Administrator upon receipt for shipping damage, completeness, and current calibration if required.

      
      

      

      
      

      The Chief Inspector shall ensure test and calibration verification of precision measurement equipment is performed within periods designated by the manufacturer or industry standards. The Chief Inspector shall inspect Reports of Calibration provided by the calibration facility to ensure traceability, accuracy, and acceptability.

      
      

      Maritime Helicopters and the technician’s personal equipment that can be checked by Maritime Helicopters Part 145 Repair Station shall be sent to the appropriate shop (Avionics for electrical and Overhaul for mechanical) with the calibration verification sheet maintained by the Inspection Department.

      
      

      On equipment for which Maritime Helicopters does not have the capability to inspect, the inspection and calibration verification will be performed by an authorized inspection facility or the equipment manufacturer.

      
      

      If calibration is out of tolerance or cannot be verified, the equipment will be removed from service until repaired or replaced.

      
      

      Equipment not checked for accuracy shall be labeled “Accuracy Unverified”. The equipment shall not be used to determine the airworthiness of aircraft or aircraft components. Seldom used equipment or equipment which requires calibration prior to use shall be labeled “CBU”. This equipment shall not be used to determine the airworthiness of aircraft or aircraft components until calibrated. The Chief Inspector shall maintain a calibration record on “CBU” items.

      
      

      Maintenance technicians are responsible for informing the Chief Inspector when they acquire new personal test or measurement equipment which requires calibration verification. The Chief Inspector will enter the equipment into the measuring and test equipment listing and, if necessary, route it to the proper shop for initial calibration verification.

      
      

4. SAFETY PROGRAM‌

   1. Safety Philosophy‌

      Maritime Helicopters is committed to the attainment of the highest level of safety in the accomplishment of our corporate mission. It is our goal to provide a safe and healthy working environment for all of our team members and, in doing so, to support state and federal laws regarding safety. Our intention in making this strong commitment is to eliminate injuries to our employees and accidental damage to equipment and/or property. It will be understood that team members of all levels of the company will be safety committee members.

      
      

      The scope of the Maritime Helicopters’ safety program includes all aspects of company practice; in flight, in the performance of maintenance; on the ramps; on the helipads; in our offices and fire prevention in every environment in which we work.

      
      

      Responsibility for implementing the safety program rests with the Maritime Helicopters Safety Officer, Officers, base and aviation safety managers, managers and supervisors at every level. That responsibility brings with it the obligation and authority to actively promote the safety program company-wide.

      
      

   2. Program Elements‌

      The following elements comprise the core elements of the Maritime Helicopters’ Safety Program. Programs will be added, deleted or changed to meet current organization and operational mission requirements.

      
      

      • Management-leadership commitment.

      • Continual Improvement through Training, Review, and Management of Change

      • Maritime Helicopters’ Safety Management System Manual

      • Emergency Response Manual and ERP Planning

      • Risk Management System (Hazard Identification, Reporting, Evaluation and Control)

      • Health, Safety, & Environmental Manuals and Injury Reporting

      • Quality and Safety Audits through the Internal Evaluation Manual/Checklists

      • Accident and Incident Reporting and Investigation with Root Cause and Trend Analysis

      • Safety Communication and Awareness

      
      

   3. Non-Punitive Investigation Policy‌

      Maritime Helicopters strongly desires to learn from all incidents, occurrences and errors made, in order to improve our systems and enhance safety. To promote and encourage the uninhibited open and honest sharing of information, all personnel are advised that no disciplinary action will be taken against any person who makes an unintentional error, even if that error results in an incident or other occurrence. Even at-risk errors (negligence) will be treated as a learning opportunity, both for the individual who made the error and the company. Only exceptional cases involving recklessness will result in a disciplinary outcome.

      
      

      All personnel are therefore encouraged to participate openly and honestly in the investigation process, without the need to protect or “cover” for a co-worker who has made an error. If such an error involves a violation of regulations, MH management will make every effort to protect all employees involved from certificate action and civil penalties by assisting employees with ASRS reporting, and by developing voluntary disclosures to Civil Aviation Authorities that emphasize organizational deficiencies rather than blaming an employee. This course of action protects both the company and the individuals involved in the violation.

      
      

      NOTE: This policy will not apply to those personnel who have behaved in a “reckless” or illegal manner, or who have committed a series of human errors that indicate a general lack of care and professionalism.
