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, 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 !)

No. An experimental with no numbers could never go into a certified
aircraft. If I were to put my C140 into the Owner Maintenance
category, in all practicality I could never put it back into
certified service. Apparently you can do it but from what I
understand and AME would have to sign off on each component part of
the aircraft which could prove impossible and would prove impratical.
If any trace numbers were missing, that part would need replacing. I
am about to start test flying a newly built Glastar. It has a brand
new certified Lycoming in it which once the paper work is finalised
and shows that it is installed in the experimental it can not go into
a certified aircraft. IIRC the Lycoming data plate is removed to
prevent it being used as certified but the indivdual part numbers
will stay intact. That is probably what was meant by the guy you
talked to.

John (at the warm,sunny, dry end of the ROCK )



Thanks John, that seems to make more sense, but if that engine was
dis-assembled, the parts could end up back into certifies aircraft,
right?

Steve, and yes, you do have better weather, good for old folks !


Well I guess anything is possible, you see reports of bogus parts getting
into reputable airline fleets.
Parts have to be tagged when removed and those get signed by AME's (I'm not
one) so I guess the system is as honest as the signature. When I buy parts
off of a local shop the stores person prints up a label that is attached to
the bag the parts go in and the invoice has a "certification" disclaimer and
both are signed by an AME on staff. This is done even if it is a couple of
rivets for an experimental a/c.

John (old ? OK I'll give you that one)


Someone with the map idea sure has a sense humor ! Likely an old,y but a goody !
