Revision in Progress Checked October 24, 2026
Both are to be reissued in the IA9100 series, which had not been published by October 24, 2026.
What It Covers
The AS9100 model adapted to two other places in the supply chain: organizations that maintain and repair aircraft and components, and stocking distributors that buy, split, and resell parts.
Who It Applies To
Maintenance, repair, and overhaul organizations (AS9110) and distributors of aviation, space, and defense parts (AS9120).
Key Requirements
- AS9110: airworthiness authority requirements, maintenance data, human factors, and return-to-service release.
- AS9120: traceability back to the original manufacturer, split-lot control, and preservation of certifications.
- Counterfeit-part prevention and supplier control in both.
What an Auditor Asks to See
- For AS9120, the full chain of certificates for a part, from the manufacturer to your shipment.
- For AS9110, a release-to-service record and the maintenance data it relied on.
Where Systems Fall Short
- Certificates of conformance that stop at the previous distributor.
- Human factors training recorded once and never refreshed.
How QES Helps
Gap assessments scoped to the role you play in the chain, not to a manufacturer’s template.
