My understanding is that your cousin cannot legally work on his certified
airplane's compass, nor can an AI or A&P. My understanding is that an FAA
approved instrument repair station is needed.

At least this is what a buddy of mine (an AI) told me one day when he was
standing over his workbench repairing a compass from another guy's *boat*.
;-)

Aircraft Spruce sells both the correct fluid for a compass and the seals for
the compass. To top off the fluid, you can simply pull the little plug (or
is it a screw ? - can't remember) at the top of the compass and use a
syringe or pipette to add fluid. I had to do that to my *boat's* compass a
few years ago. Apparently compasses are vented and the fluid can evaporate
over time.

Cousin has a glider and said that he needs to add fluid in compass.

Is this something that can be done? If so, can he do it or does an A&P
have to do it? What is the fluid?

Also, he is also wanting to replace the tubing between the pitot tube and
the instrument. Again, can he do this or does an A&P have to do it?


Thanks...
