Introduction
FAA Advisory Circular 00-56 establishes a civil aircraft parts distributor accreditation system. This system involves voluntary industry oversight. The FAA strongly endorses participation in this system. FAA AC 00-56 lists ASA-100, ISO 9001, AS9100, AS9120, and AS9110 as acceptable quality system standards.
The current revision of AC 00-56 is revision B Change 1 was released on April 26, 2024. The FAA also released an InFO24004. Links to all documents are below. One of the changes included the removal of the TAC 2000 standard as an acceptable quality system standard. There is a sunset date for all TAC 2000 certificates of January 24, 2025. Additional details regarding TAC 2000 can be found in the InFO24004.

When is a Distributor Considered Accredited and What is the Process?
Distributors become officially accredited to FAA AC 00-56 when they appear on the Voluntary Industry Distributor Accreditation Program Database. The Aviation Suppliers Association manages the database for the FAA.
- A cover letter that meets the requirements of AC 00-56B (Appendix 2 is the sample letter). ASA has created a template letter that companies may use.
- A valid certificate, signed by the accreditation organization. The certificate must indicate that you met FAA AC 00-56B and an acceptable quality standard. For some ISO based filings this requirement will be fulfilled with a certificate for the ISO based standard and a certificate for FAA AC 00-56.
