Aerospace manufacturers do not just manage suppliers. They inherit supplier risk.
Under 14 CFR Part 21 Subpart G, FAA requirements around production certificates include quality systems, inspections, tests, quality manuals, and production controls. The FAA's production approval process includes audits of the applicant's organization, production facility, quality system, and design data.
That means outsourced work still has to fit inside the manufacturer's compliance story.
If a supplier performs a special process, provides a critical component, changes a manufacturing method, substitutes material, or misses a flowed-down requirement, the impact can land squarely on the production approval holder.
Supplier oversight should answer practical questions:
Who is approved to do what? Which specifications apply? Are special processes qualified? Are inspection records complete? Are material certs traceable? Are changes communicated and approved? Are supplier escapes investigated and trended?
The challenge is not simply collecting supplier documents. It is knowing whether those documents prove the right level of control.
What manufacturers should pay attention to:
Supplier requirements need to be flowed down clearly, verified consistently, and connected to the product configuration.
Bottom line: In aerospace, a supplier's process can become your compliance problem. Treat supplier control like part of the aircraft.
