AC 21-43, ADVISORY CIRCULAR: PRODUCTION UNDER 14 CFR PART 21, SUBPARTS F, G, K, AND O (16 OCT 2009)., This advisory circular (AC) provides information about Title 14, Code of Federal Regulations (14 CFR) part 21, Certification Procedures for Products, Articles, and Parts. This AC addresses the manufacturing and production requirements of part 21, subpart F, Production Under Type Certificate; subpart G, Production Certificates (PC); subpart K, Parts Manufacturer Approvals (PMA); and subpart O, Technical Standard Order (TSO) Approvals. This AC provides information on how an applicant for a production approval or a current production approval holder (for this AC both are referred to as a PAH) should develop and maintain their quality systems. This guidance aids the PAH in developing a quality system that both meets the needs of the PAH and is compliant with the regulations. This AC is not mandatory and does not constitute a regulation. This AC describes an acceptable means, but not the only means, to comply with these requirements. However, if you use the means described in the AC, you must follow it in all important respects.
