PER CHAMPION: The STC/337 is an approval. Companies get STCs (which require 337 submittals) when they seek approval on their own. PMA approval can only be granted when the manufacturer that uses the part provides a PMA assist letter to the component manufacturer showing that the parts are TCs in their engine. Again, all components included in an a/c engine will be TC approved (certified in the orginal engine); or STCd (supplemental TC) approvals; which happen at some point after the original certification event, 337 submittal shows the FAA who & why it was done.
