"A pilot with a tool box." or "A politician
with a good idea."
FAR 43.7(f) says that a Part 61 pilot may do preventative maintenance
on an aircraft used in Part 91 operations provided it does not
involve complex assembly operations. The pilot can approve for
return to service after work under FAR 43.3(g) 29 items are listed.
The complete index is in FAR Part 43, Appendix A.
The pilot can:
Replace safety belts
Remove, install and repair tires
Replenish hydraulic fluid in reservoir
Replace, clean and space spark plugs
Replace and service batteries (Not ELT)
Replace bulbs, reflectors and lenses in lights
Trouble shoot and repair landing light circuits
Replace defective safety wiring and cotter keys
Servicing landing gear shocks by adding oil or air
FAR 91.7 makes the pilot responsible for the airworthiness
of an aircraft. Assumption of this responsibility carries with
it responsibility to become and remain knowledgeable about the
aircraft and its systems. The owner/operator is responsible for
the actual financing of the maintenance. A certified mechanic
must inspect any work done and make required entries in the records
of the aircraft. FAR 43.3(d) requires that the mechanic personally
observe the work and be available while the job is in progress.
However, the FAA gets to second-guess all actions by these parties
if something occurs.
The best care you can show toward your engine is to use it
along with some good pilot procedures. A sitting engine will rust
and corrode. Avoid descents with reduced power which may cause
shock cooling; high rpm starts which fail to provide required
initial lubrication; and, excessive leaning at high rpm which
will burn exhaust valves.
