Key Takeaways:

FAR 43.3 permits pilots to perform preventive maintenance on aircraft they own or operate, exclusively for noncommercial Part 91 operations.
Appendix A of Part 43 lists specific allowed tasks, such as tire changes, servicing shock struts, replacing lights, batteries, and most tray-mounted avionics (excluding transponders, DMEs, and autopilots), as well as spark plugs and filters.
Pilots attempting maintenance for the first time are advised to consult with an experienced aviation mechanic (A&P) to ensure proper procedures and safety.

Question: I just bought a Cessna 172 to finish my private pilot certificate. I’ve been working on cars since I was in my teens, so I think I can do my own maintenance. But doesn’t the FAA limit what a pilot can do on their airplane?

Answer: FAR 43.3 permits a pilot to perform preventive maintenance on an aircraft they own or operate, provided it is used strictly for noncommercial operations under Part 91, so no flight instruction or scenic flights.
