F.P.
I hope your right (about the automobile association),but the problem is out there and its huge.
However whatever the level of bogus parts there are in the US inventory the FAA or for that matter any aviation authority will never be able to control it fully as there is to much money to be made.
the engineer at the end of the line has to make the judgment based on what ?????
paperwork sometimes copied several times/shipped several times around the world before use and engineers/mechanics etc under pressure to not cause delays.
