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 Carlisle


   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 !)

   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 !

   In theory, you could take a pair of Cessna 150 wings, strap them to a home made fuse, add your own tail feathers and engine and register the plane that it was built from "parts or plans". If it has a certified engine/prop combo you can fly it for 25 hours and then you will have a standard EAB A/W cert. Later, you could take the wings off and sell them as from and they can be put back onto a Cessna 150 certified plane. Even if you modified them, as long as the A&P can return them to meet the TCDS and is willing to sign the log book, it's legal.

   Lost of responsibility with that number and the signature when we put it in the log book :). Kind of like painting a target on our backs.

   Great idea. Put composite wings from a home built on a Bellanca Cruisair
   with rotted out wood wings. Something like a Lancair ES.

   Paul Lamar

Funny you mention that Paul, I have a Bellanca Viking with a blown 300 hp Continental that will be over 50K to replace. The FAA said I could only use a certified engine in the certified plane, and that it would have to be substantially modified to comply with the 51% rule for amateur built.
And, I have my Wheelers, with composite wings very similar to the Lancair. I have been contemplating making a copy of the wings on Wheeler 2 and using these on the Viking fuse with a 3 rotor in the nose.

Making a mold of my existing wings is not all that difficult- :)
