Check 65.81(a). A certified mechanic can't perform any repairs or alterations on instruments. So legally you can't service a compass and return it to service as an A&P.

Service"? Yes! Repair, absolutely not...

In Canada, you can. As long as you have the manufacturer's manual and the procedures do not require specialized equipment, you can repair. Same with servicing.

A compass is considered an aircraft instrument by the FAA. Part 65 prohibits FAA mechanics from performing any maintenance including servicing on any instruments including compasses. The only procedure a FAA mechanic can perform on a compass is a compass swing and update the compass card, which is a required placard.

If you read the appropriate paragraphs in far 43 and 65, the word instrument is straight forward, but if you go to Part 1 and look up definition of "instrument", the attribute for a compass is not listed. therefore leaving servicing and repair of a wet compass to those mech's that have previously performed that function. This is my understanding. Now getting the FAA or local FSDO to go along with this is another story.
