AS9120 Certification Services: Aerospace Distributor Quality Management System

AS9120 is a sector-specific quality management system standard for the aerospace industry. It was designed for aerospace suppliers known as “stockist distributors” or “pass-through distributors” to aerospace OEMs. These are companies that resell, warehouse, and distribute parts for aircraft manufacturers rather than adding value or working on the products themselves.
AS9120 is one of the quality system standards the FAA recognizes under Advisory Circular 00-56, Voluntary Industry Distributor Accreditation Program. The current revision, AS9120B, was published in 2016 and is built on ISO 9001:2015.
Accredited certification
PJR is accredited by ANAB to certify companies to AS9120 and is authorized to perform accredited AS9120 certification audits. That accreditation comes from ANAB, so your certificate is recognized internationally through the IAF Multilateral Recognition Arrangement. Certificates are also recorded in the IAQG OASIS database, where OEMs and prime contractors search for approved distributors.
Who needs AS9120?
Stockist and pass-through aerospace distributors, parts brokers and resellers, and raw material or hardware distributors serving aviation, space, and defense: businesses that warehouse and resell parts without altering their design or manufacture.
Benefits of AS9120 certification
- Demonstrates traceability and counterfeit-prevention controls to OEMs and prime contractors
- Brings record control, chain of custody, and conformity evidence under one auditable system
- May reduce the frequency of customer and second-party audits
- Gains visibility in the IAQG OASIS database, where aerospace buyers search for approved distributors
- Meets a purchasing requirement that OEMs and primes often set before sourcing from a distributor
