AS9110 Aerospace Maintenance Organisations
Current edition: AS9110C · next: IA9110
The quality management standard for aviation maintenance, repair and overhaul organisations. It builds on ISO 9001 and AS9100 with requirements that reflect airworthiness regulation and maintenance practice.
IA9110Revision coming
AS9110C is being revised as IA9110
The International Aerospace Quality Group is revising the 9100 series, renaming AS9100 as IA9100 and its companion standards accordingly, aligned with ISO 9001:2026. Publication is expected from late 2026, followed by a transition period. Systems we build to AS9110C now are designed to move to IA9110 with a focused gap review.

How we work
Path to certification
One AEC methodology from first assessment to certificate, delivered by registered lead auditors.
- AssessGap assessment against AS9110C, scope and roadmap
- DesignProcesses, risk register, policy and documented information
- ImplementProcesses embedded with coaching for process owners
- TrainAwareness for all staff and internal auditor development
- VerifyInternal audit, management review and mock certification audit
- Certify & sustainStage 1 and Stage 2 support, then surveillance readiness
Full implementation
No existing system. We design and implement from the ground up.
Typically 6 to 9 monthsGap remediation
Some documentation in place. We close the gaps and prove effectiveness.
Typically 5 to 7 monthsUpgrade & integration
We add maintenance requirements to your ISO 9001 or AS9100 system.
Typically 4 to 6 months
Who certifies
Certification under the IAQG scheme
AS9110 certificates are issued by certification bodies accredited under the IAQG Industry Controlled Other Party (ICOP) scheme, and recorded in the IAQG OASIS database. AEC prepares you for that audit; the certification decision is theirs.
CB-neutral
We help you select an ICOP-accredited body that suits your customers.
Audit-ready
Mock audit and closed corrective actions before Stage 1 and Stage 2.
No guarantees
We prepare you thoroughly and never promise an outcome only an independent auditor can decide.

Questions
AS9110 FAQ
Does AEC issue the AS9110 certificate?
No. AS9110 certificates are issued by ICOP-accredited certification bodies. AEC prepares your organisation for that audit.
Does AS9110 replace our aviation authority approval?
No. Authority approvals remain separate. AS9110 provides a quality system that supports them and that customers recognise.
AS9110 or AS9100?
AS9110 is for maintenance, repair and overhaul organisations. AS9100 is for design and production. Some organisations need both.
Should we wait for IA9110?
No. AS9110C certification remains valid through the transition after the new edition is published.
