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 !

   when you pull an engine you SHOULD log it in the air frame and power plant logs, the power plant logs should go with the engine anywhere it goes if its installed in an amateur built its no longer certed. and it was logged as removed from air frame. so before it could but put back on to a certified aircraft it would have to go out for an over haul to return it to as manufactured condition (i work in the aircraft component's repair industry), no if some one say didnt log the fact it was installed in an experimental and knowingly re installed on a certified aircraft they could go to jail for that and fines all that fun stuff.

Guys, as I understand it I can take the certified engine/prop off of my experimental and place it back on a Seneca I where it came from. Even without complete logs, by installing it I am certifying that it is Airworthy. Which means that I have checked the parts, made sure no non-certified parts are on it, all parts that are on it appear to be airworthy. I can put it on the plane, test it and sign the log book with my A&P number and all is good as far as the FAA is concerned.

Some interesting facts:

As as A&P I can replace the entire tail section of your certified airplane with one from the factory or another airplane, but to replace the skin on the rudder I have to have an IA sign off on it. I can replace the engine with one just like it from a donor plane, but to overhaul the one you have I have to have an IA sign off on it.

I can take your landing gear off completely and replace them with new factory legs or ones from a donor aircraft, but to replace the gear brackets technically requires a 337 and again an IA signoff.

If I have the TCDS and a data plate for any airplane, an A&P can build the entire plane and it will be certified and airworthy. All he has to do is use the right parts and AC 43.13

There are more rules like this, lots of them.

Basically, an A&P can install anything with a data plate that meets your TCDS and it will be airworthy.
By signing his name and cert number, he is certifying that the plane is airworthy at the time he signed it.

And, if you crash the FAA goes to 2 people first- the last A&P that worked on the plane and the CFI that gave you your last BFR.
And the lawyers are in the car behind the FAA.
