I do know that is difficult DAR's/DER's to look in the FAA's systems for STCs to be used as the basis for "approved data" for the sake of intellectual property. They have to do this by finding thru word of mouth an airplane that has an STC approved, get the $10 CD and use that as a basis. The reasoning being so that someone that went thru the trouble of getting an STC can't be easily copied verbatim as a basis for 337 approvals, thus protecting their intellectual property at least somewhat.
