FAR Del 43, Bilaga A, berättar exakt vad förebyggande underhåll du kan göra som ägare till ett flygplan som inte används för kommersiell service.
Den snabba avloppsventilen på vår äldre Mooney har börjat läcka och göra lite röra. Vi gick till vår lokala butik och bad dem att schemalägga att ersätta det för oss och de berättade att de är bokade ut flera veckor och vrider bort några mindre jobb på grund av att de är underbemannade -_-
Jag nämnde att vi gör våra egna oljebyte och föreslog att om vi var praktiska nog att hantera en oljebyte kunde vi bara ta bort snabbflödet och ersätta det med en originalplugg och han gav oss gärna en gratis ledning. Det skulle få oss till vår nästa oljebyte och vi kunde få den ersatt då.
Del 43 gör det möjligt för ägarna att göra oljebyten och ersätta snabbavloppsventilen med en plugg ser ut att vara i grunden identisk med oljebyteprocessen om du inte hade en snabb avloppsventil i första hand: ta bort kontakten, fånga oljan, byt ut pluggen, lägg till ny olja. Men om jag ska gå ner på den vägen, varför, varför inte bara ta en ny snabb dränering av flygplansgran och sätt den i stället för pluggen?
Är vi på höger sida om underhåll av ägaren om vi byter ut snabbflödet med en plugg som A och P föreslog? Vad sägs om om vi byter ut snabbflödet med en ny? Eller ska vi få ett tecken från en A & P
Det här är vad FAR tillåter dig att göra som förebyggande underhåll om du inte är en certifierad mekaniker:
(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, the 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) Trouble shooting 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. removal of the propeller or disconnection of flight controls.
(19) ...
(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.
(28) 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 certificiate 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 part 91 of this chapter.
(32) Updating self-contained, front instrument panel-mounted Air Traffic Control (ATC) navigational software data bases (excluding those of automatic flight control systems, transponders, and microwave frequency distance measuring equipment (DME)) provided no disassembly of the unit is required and pertinent instructions are provided. Prior to the unit’s intended use, an operational check must be performed in accordance with applicable sections of part 91 of this chapter.

FAR Del 43, Bilaga A, berättar exakt vad förebyggande underhåll du kan göra som ägare till ett flygplan som inte används för kommersiell service.
Det är en intressant fråga. I själva verket kan någon ersätta en del på egen hand, men för att vara laglig måste du vara under överinseende av en certifierad A & P och få den inspekterad / avloggad. FAA, del 43.3 (d)
Kort svar är JA.
