From my understanding, the FAA (and EASA) approval of articles (either under PMA, TSO or type certification procedures) or parts applied to repair or replacement parts. Is this correct or do these procedures also apply to the articles originally manufactured by OEMs?
Ie. does the FAA and EASA govern the article/part certification procedures for OEMs (and do the companies that supply these aerospace OEMs with their parts need to be PMA's and follow TSOs etc) or only for repair and replacement manufacturers?
