When is a compass swing due? I cant find anything in the FAR's. Yes I can understand the reasons when avionics or the compass is replaced. But I was told it is due anytime an engine is changed, after structural repair.

If an aircraft is on a AAIP program, it's done annually. On smaller aircraft, it is done at the annual inspection. On newer aircraft with EFIS and flux valves, you can simply do a correlation check against the compass rose on the MFD.

Never done one after an engine change or after any structural repair. I've done it after replacing the standby compass. And, I believe we do them at "c" check.

Of course, I'm talking ATC aircraft.

Just wanted to know cause I got it wrong on a test. The question "they" had was: When is a compass swing due? After engine change, airframe repair, 12 months, or all the above. Their answer was all of the above. I didn't argue but i asked others later and the response was "what type aircraft?" For a UH-1 yes but others it all depends on the manual, situation, etc.
The questions are written by my employer, and the tests are not very well concieved. It is a brief window into their limited views(we do multiple platforms). My days there are numbered. With the current state of aviation maintenance in the US it might be awhile.

According to the FARs, (I believe it's somewhere in 43), it's due at least evry 24 months, or when an equipment change is made.

A compass swing is only required when there's reason to question the accuracy of the system or a repair or replacement is made that could cause an error.
It may also be required if your company changed the compensation card style.
There's no time requirement unless it's written into your company's maintenance procedures manual.
Or I missed something in 43, 91, 121, or 135. I didn't look in any others.

Cards may be incremented in 10 or more degrees per compensation correction. If you are currently using a card with corrections every 15 degrees and change to a card with 10 degree increments you'll have to go to the rose and do a swing to determine the compensation for each heading.
