Best AS9100 Certified CNC Machining Shops

AS9100 is the aerospace and defense quality management system standard required by major primes including Boeing, Airbus, Lockheed Martin, and the U.S. Department of Defense. CNC shops holding AS9100 certification have implemented robust first-article inspection (FAI), configuration management, counterfeit parts prevention, and risk management processes on top of the ISO 9001 foundation. This list focuses on shops whose AS9100 scope covers CNC machining of aerospace components.

Why these suppliers?

  • AS9100 certification goes beyond ISO 9001 to include aerospace-specific requirements for first-article inspection, key characteristics, configuration management, and counterfeit parts control.
  • All listed shops have been audited by accredited AS9100 registrars and appear in the IAQG OASIS database — the authoritative registry of aerospace quality management certified organizations.
  • These shops have documented experience with aerospace alloys, aerospace surface finish requirements, and the first-article inspection report (FAIR) process required by AS9102.

Frequently Asked Questions

What is AS9100 certification and why is it required for aerospace CNC machining?
AS9100 is an aerospace and defense quality management system standard developed by the International Aerospace Quality Group (IAQG). It includes all ISO 9001 requirements plus aerospace-specific additions covering product realization planning, first-article inspection (FAI), key characteristics identification, configuration management, counterfeit parts prevention, and risk management. Most aerospace prime contractors and Tier 1 suppliers require their machine shops to hold AS9100 certification before award of machined component contracts.
Where can I verify a CNC shop's AS9100 certification?
AS9100 certificates can be verified in the OASIS (Online Aerospace Supplier Information System) database at iaqg.org/oasis, which is maintained by the IAQG and contains records of all certified organizations globally. Always verify that the certificate scope specifically covers CNC machining, and that the certificate is current and not suspended.
Do I need AS9100 for all aerospace machined parts?
Requirements vary by customer and program. Commercial aviation Tier 1 and Tier 2 suppliers typically require AS9100 from their machine shop supply chain. Defense programs may additionally require ITAR registration and Nadcap accreditation for special processes. Non-structural interior components or ground support equipment parts may be acceptable with ISO 9001 alone, but confirm requirements in the purchase order or contract.
