MP, Can you point me to the legislation that details this "back to birth" requirement.
You're right, back to birth isn't actually stated. It is put this way:
The first airworthiness review of each aircraft must cover the entire history of the aircraft to establish a baseline of airworthiness.
Back to birth was used a bit loosely by me in that post, but the requirement is the same. GM 42.900 (1) refers and it can be found at the link provided below. The wording in the first paragraph should be noted regarding this being the minimum requirement.
I didn't mean anything with regard to Fokker aircraft, what I meant is that this process is extremely complex for aircraft (and major components) with a colored life history.
