EASA Form 1 - Parts from non approved sources
Folks, grateful for help with the following.
About a month ago I found on the web a document relating to the acceptability of parts for aircraft use. I think the phrase "Accepability of Parts" was either a main or sub-title. In addition to explaining the use of the EASA Form 1 and the use of standard parts in conjunction with a c of c it had a section explaining what would need to be done to allow part from a non-approved manufacturer to be issued with a Form 1, eg additional inspection, testing or QA. My interest is in engines derived from automotive applications and their associated spares.
I cannot remember where I found the information and considerable time spent on a general web search combined with searching the CAA, FAA and EASA sites, and PPRUNE has been unsuccessful.
Any pointers to an authoritative source for this information would be a big help.
Thanks

Thanks Rigga but I've already been there. It almost gets to what I viewed previously. I can't see any GM for this section, which is where I'expect to find what I'm looking for, only AMC.
The reason for the question is to settle a discussion with a maintenance organisation that wants a Form 1 for every part supplied. I'm trying to educate them. Essentially we have a light aircraft piston engine derived from an automotive application and its spares originate from a vehicle manufacturer.
The source I read explained very nicely the difference between parts from a POA source (Form 1), standard parts and non-hazardous parts. It went on to explain the process by which parts from a non-POA source could be issued with a Form 1, such as additional testing, inspection and QA. The part would then be given a new part number, indicating that some 'modification' process had been carried out, and could be issued with a Form 1.
I've been through Parts 21, 145 and M, and searched the web with many permutations of 'EASA Form 1, non approved parts, applicability of parts'.
I've only a few hairs left now, though there weren't many to start with.
If you can think of anywhere else I'd be grateful but don't go overboard.
Thanks again

Ussry - raise a new thread; you're off topic.
R2G2 - you are in the realms of Part 21 here. I think the Thierlert/Centurion diesel engines originate from the engine fitted to the 'A' series Mercedes so you are looking at a similar scenario (although that might have occurred under a German national process prior to the full implementation of Part 21 in 2004). I think you'll find the information through a long trawl through Part 21, AMC, GM and decisions. Call the UK CAA at Gatwick, too.

Thanks Bus. I'm trawling when I can get the time from the main job. Even if I can't find the specific reference I saw I've now got enough information to educate the maintenance organisation in the correct use of the Form 1.
