Aerospace Quality Management: 3 Essential AS9100 Standards

In most industries a quality escape costs money. In aerospace and nuclear it can cost lives, and the quality regimes reflect that. Aerospace quality management under the AS9100 family, and nuclear quality assurance under NQA-1, share a defining trait: the documentation is not evidence of the work, it is part of the work. This guide covers both and how they differ from ordinary ISO 9001.

Both build on ISO 9001, so the management-system foundations will be familiar.

The AS9100 family

All three extend ISO 9001 rather than replace it, adding sector requirements around configuration management, counterfeit part prevention, product safety, special processes and first article inspection. Certification is administered through the industry’s own oversight scheme, and results are published to a shared database that customers check.

Our AS 9100/9110/9120 Aerospace QMS Toolkit provides 38 templates covering all three variants, including the quality manual and policy, the code of ethics and business conduct, KPI catalogue, implementation roadmap and the sector-specific procedures.

What makes aerospace quality different

Traceability is absolute. You must be able to trace a part back through its processes, materials and operators, which forces record-keeping discipline well beyond ordinary manufacturing.

Counterfeit parts are a named risk. The standards require deliberate controls on sourcing and verification, not a general expectation of good procurement.

Special processes need qualification. Welding, heat treatment, non-destructive testing and similar processes are qualified and their operators certified, because the result cannot be fully verified by inspecting the finished part.

The nuclear parallel: NQA-1

Nuclear quality assurance takes the same logic further. NQA-1 governs quality assurance for nuclear facilities, where a documentation failure is treated as a safety failure in its own right — if you cannot evidence that a control operated, regulators proceed as though it did not.

Its distinctive feature is the graded approach: the rigour applied scales with the safety significance of the item or activity, so not everything carries the full weight. Getting that grading defensible, and documented, is the first real task in an NQA-1 programme.

Our NQA-1:2024 Nuclear Quality Assurance Toolkit provides 100+ templates including the nuclear quality assurance program manual, quality assurance policy statement and program description, the graded approach application procedure, implementation plan and the roles and responsibilities matrix.

What both demand that ISO 9001 does not

Evidence that survives scrutiny years later. The same expectation applies to any in-house test or calibration laboratory supporting the work, where ISO 17025 governs competence and metrological traceability rather than ISO 9001. In both sectors an auditor may examine records long after the people involved have moved on, so records must be complete, controlled and legible without their authors present. That is a documentation culture, not a filing decision, and it is the part organisations moving up from ISO 9001 consistently underestimate.

Frequently asked questions

Do you need ISO 9001 before AS9100?

No. AS9100 incorporates ISO 9001 in full, so you certify to AS9100 directly rather than holding both. Existing ISO 9001 certification does make the transition considerably shorter.

Which AS9100 variant applies to a distributor?

AS9120, which covers stockists and distributors. It focuses on traceability, records and counterfeit prevention rather than the design and production requirements in AS9100.

Is NQA-1 a certification?

It is generally applied contractually and assessed through audits by customers and regulators, rather than through a certification body in the way ISO standards are.
