21-55 AIR-100 Process to Support FAA Findings of Undue Burden or No Undue Burden for PAHs Requesting to Use a Manufacturing Facility Located Outside of the United States This advisory circular (AC) contains information and guidance to production approval holders (PAH) located in the United States requesting Federal Aviation Administration (FAA) approval to use manufacturing facilities located outside of the United States. This AC provides information for PAHs in accordance with the regulations cited in Title 14 of the Code of Federal Regulations (14 CFR) part 21, Certification Procedures for Products and Articles. For the purposes of this AC, manufacturing facilities includes production certificate (PC) extensions, associate facilities, and suppliers located outside the United States. Before approving a PAH’s request to use manufacturing facilities outside of the United States, the FAA must consider certain factors that may impact the FAA’s ability to administer the requirements of part 21 that could potentially cause the FAA an undue burden. This AC outlines the necessary information the PAH should submit to the FAA as part of the PAH Project Initiation Plan included as appendix A to this AC (hereafter referred to as a “project plan”) to demonstrate that the proposed activity will not cause an undue burden 08-01-2016
