Another party’s STC that is incorporated during pro- duction and is referenced in and becomes a part of the TC need not be shown on the PLR. When a TC is amended to incorporate data approved under an STC, only the TC should continue to be shown on the PLR.
c. When the PC holder of a TC obtains an STC, or related licensing agreement, but does not make the STC an integral part of the TC, the PC holder may incorporate the STC in production products prior to OAC approval, provided that —
1. The PC holder makes application to the FAA to add the STC to its PLR,
2. The quality system data are revised as nec- essary, and
3. The engineering data submitted for the STC approval provide all the details necessary for manufacture and for making conformity determinations.
d. When a PC holder elects to use neither of the foregoing methods, the TC holder may incorporate an STC modification into production products only after OAC, in accordance with the provisions of part 43.
Only the last method after OAC requires the provision under Part 43.
Please note that at OAC we must list the STC incorporated at build that are installed by Method 2 (incorpora- tion by reference in the TC Data) or 3 (addition to the PLR), we must list the STC on the application for airworthi- ness (FAA Form 8130-6), we must make a record in the aircraft logbooks, we must provide any applicable AFM/ POH Supplements, and provide instruc- tions for continued airworthiness.
Textron Aviation does not complete FAA Form 337 because we did not alter from aircraft at original build; but incorporated these STC at build. The FAA Record of these STC incorporated at build are listed in Block III of the original FAA Form 8130-6 which should be on file in the FAA’s AFS-750 database. If they cannot find a copy in AFS-750 Textron Aviation can provide one from our archive records.
If the aircraft is exported without issuance of a Standard C of A then the STC will be listed on the Export C of A (FAA Form 8130-4) and on the Application for Export C of A (FAA Form 8130-1). Copies of both are filed with the FAA at AFS-750 in OKC. Same rules apply about providing the required STC documents for logbook entries, Supplements and ICAs.
