    Preventive maintenance

    For those of you who do not possess an A&P mechanic license, this is a list of what you are permitted to accomplish as maintenance as supplied by my FAA-PMA today.

    (c)Preventive maintenance.
    Preventive maintenance is limited to the following work, provided it does not involve complex assembly operations:

    (1) Removal, installation, and repair of landing gear tires.
    (2) Replacing elastic shock absorber cords on landing gear.
    (3) Servicing landing gear shock struts by adding oil, air, or both.
    (4) Servicing landing gear wheel bearings, such as cleaning and greasing.
    (5) Replacing defective safety wiring or cotter keys.
    (6) Lubrication not requiring disassembly other than removal of nonstructural items such as cover plates, cowlings, and fairings.
    (7) Making simple fabric patches not requiring rib stitching or the removal of structural parts or control surfaces. In the case of balloons, them making of small fabric repairs to envelopes (as defined in, and in accordance with, the balloon manufacturers' instructions) not requiring load tape repair or replacement.
    ( 8 ) Replenishing hydraulic fluid in the hydraulic reservoir.
    (9) Refinishing decorative coating of fuselage, balloon baskets, wings tail group surfaces (excluding balanced control surfaces), fairings, cowlings, landing gear, cabin, or cockpit interior when removal or disassembly of any primary structure or operating system is not required.
    (10) Applying preservative or protective material to components where no disassembly of any primary structure or operating system is involved and where such coating is not prohibited or is not contrary to good practices.
    (11) Repairing upholstery and decorative furnishings of the cabin, cockpit, or balloon basket interior when the repairing does not require disassembly of any primary structure or operating system or interfere with an operating system or affect the primary structure of the aircraft.
    (12) Making small simple repairs to fairings, nonstructural cover plates, cowlings, and small patches and reinforcements not changing the contour so as to interfere with proper air flow.
    (13) Replacing side windows where that work does not interfere with the structure or any operating system such as controls, electrical equipment, etc.
    (14) Replacing safety belts.
    (15) Replacing seats or seat parts with replacement parts approved for the aircraft, not involving disassembly of any primary structure or operating system.
    (16) Troubleshooting and repairing broken circuits in landing light wiring circuits.
    (17) Replacing bulbs, reflectors, and lenses of position and landing lights.
    ( 18 ) Replacing wheels and skis where no weight and balance computation is involved.
    (19) Replacing any cowling not requiring removal of the propeller or disconnection of flight controls.
    (20) Replacing or cleaning spark plugs and setting of spark plug gap clearance.
    (21) Replacing any hose connection except hydraulic connections.
    (22) Replacing prefabricated fuel lines.
    (23) Cleaning or replacing fuel and oil strainers or filter elements.
    (24) Replacing and servicing batteries.
    (25) Cleaning of balloon burner pilot and main nozzles in accordance with the balloon manufacturer's instructions.
    (26) Replacement or adjustment of nonstructural standard fasteners incidental to operations.
    (27) The interchange of balloon baskets and burners on envelopes when the basket or burner is designated as interchangeable in the balloon type certificate data and the baskets and burners are specifically designed for quick removal and installation.
    ( 29 ) The installations of anti-misfueling devices to reduce the diameter of fuel tank filler openings provided the specific device has been made a part of the aircraft type certificate data by the aircraft manufacturer, the aircraft manufacturer has provided FAA-approved instructions for installation of the specific device, and installation does not involve the disassembly of the existing tank filler opening.
    (29) Removing, checking, and replacing magnetic chip detectors.
    (30) The inspection and maintenance tasks prescribed and specifically identified as preventive maintenance in a primary category aircraft type certificate or supplemental type certificate holder's approved special inspection and preventive maintenance program when accomplished on a primary category aircraft provided:
    (i) They are performed by the holder of at least a private pilot certificate issued under part 61 who is the registered owner (including co-owners) of the affected aircraft and who holds a certificate of competency for the affected aircraft (1) issued by a school approved under § 147.21(e) of this chapter; (2)issued by the holder of the production certificate for that primary category aircraft that has a special training program approved under§21.24 of this subchapter; or (3) issued by another entity that has a course approved by the Administrator; and
    (ii) The inspections and maintenance tasks are performed in accordance with instructions contained by the special inspection and preventive maintenance program approved as part of the aircraft's type design or supplemental type design.
    (31) Removing and replacing self-contained, front instrument panel-mounted navigation and communication devices that employ tray-mounted connectors that connect the unit when the unit is installed into the instrument panel, (excluding automatic flight control systems, transponders, and microwave frequency distance measuring equipment (DME)). The approved unit must be designed to be readily and repeatedly removed and replaced, and pertinent instructions must be provided. Prior to the unit's intended use, and operational check must be performed in accordance with the applicable sections of part91 of this chapter.

    Did something change?

    When I work on my PA-28 I'm grateful that I have an IA who is prepared to supervise and sign off any work I want to do myself. FAA considers removing landing gear from the wings and replacing it, or changing a cylinder, to be beyond my competency. Fortunately he does not share that view. Not quite as good as being EAB but close.

    I don't know if something changed since it is not a list I'm obligated to follow.
    In your case, you are accomplishing maintenance under the supervision of an A&P mechanic. Therefor you are not limited to those items on the list. EAB has far more leeway in that it is not obligated to comply with the FARs which are applicable to certificated aircraft. To be more accurate you are not working under an IA's supervision since an IA is authorized to perform inspections which he is not allowed to delegate to any other person. You are working under his A&P certificate, which is permitted.

    The list of allowed preventive maintenance tasks is defined in 14 CFR part 43 Appendix A section (c).

    https://www.ecfr.gov/current/title-1...pter-C/part-43

    I didn't cross check every item but a spot check seems to show it's the same list.

    And don’t forget, if you do perform preventive maintenance listed on 43 Appendix A, you are also required to make a maintenance record entry per 43.9.

    Why do you ask? Does 30 apply? How many here own and maintain a primary category aircraft?

    Does changing oil fall under lubrication(6)? Says we can (23) replace oil strainers or filter elements.

    And then there is this letter from the FAA’s Legal Dept. to muddy those waters…

    https://www.faa.gov/about/office_org...rpretation.pdf

    Specifically paragraph 4 that says “limited to the following work” is not controlling and you aren’t limited to only that work.

    Another fun fact is you’re required to have the maintenance manual out and open to the appropriate page. I don’t recall the exact FAR.

    Common sense trumps regs when remote and away from a maintenance base. Save yourself and others.

    I had never heard of "primary" category and had to look it up. BTW, you can fix the by leaving a space before the parenthesis like ( 8 ) as the former is code for one of the smileys.
