Hi, I was talking with a long time aviator here in Canada and he told
me all certified aircraft engine parts used for amateur built
aircraft have to have all original tracking number obliterated before
install . WOW !

Steve I'm not sure your getting good info? I'd have to double check
w/ the local inspector but I've not heard of having to do this (in
Canada), we certainly haven't on the a/c we're building.

Fwiw Jarrett Johnson (Also Canadian)

I fly a couple of certified experimental's with numbers. It could be
some people don't want anything traceable back to them and remove all
their numbers.

John Gibbons (opposite end of Steve's rock)

John, okay, so a certified aircraft engine, all numbers intact, could
be removed from a certified aircraft, the engine placed into a
amateur built aircraft, and run and maintained under those rules, and
then one day be installed back into a certified, with no record of
it's alternative life. Just trying to understand how the DOT can
track that use, or not !

Steve Carlisle (at the better end of the ROCK !)

Steve, the engine must be accompanied by a Tech-log which notes all repairs and modifications etc. The tech log would note that the engine had been removed from the first a/c (and possibly installed on an experimental a/c). If someone wanted to reinstall the engine back on a certified, they would need these logs and most likely (mechanic would need to confirm this) the engine would need a complete tear down to confirm all components are "in-tolerance" etc. The cost would most likely be prohibitive.

It's one thing to take parts off a certified a/c and use them on an experimental, very different process to take them off the experimental and put them back on a certified a/c. If it can be done at all.

Fwiw
