Aerospace parts carry zero tolerance for failure. A single non-compliant bracket, turbine component or structural fitting can trigger catastrophic flight safety risks, costly FAA/EASA audit penalties, and multi-month program delays.
Unlike general industrial sourcing, aerospace procurement cannot rely on low pricing or fast lead times alone. Every manufacturing vendor must pass layered qualification covering certifications, equipment capability, material traceability, non-destructive testing and full batch audit trails.
This standardized checklist is built for procurement teams evaluating precision CNC, SLM additive, sheet metal and molding suppliers for airframe, engine, satellite and UAV programs. It separates compliant, audit-ready manufacturers from generic job shops that cannot meet aerospace regulatory requirements. All criteria align with AS9100, ISO standards and OEM Tier 1 internal qualification rules.
Pre-Qualification Initial Screening (First-Round Quick Check)
Run this fast preliminary filter before scheduling formal audits to eliminate unqualified vendors early:
- Completed vendor self-disclosure questionnaire with company production scope
- Valid AS9100D certification (not just generic ISO 9001)
- Proven aerospace customer reference list (OEM / Tier 1 program names available upon request)
- Clear list of supported aerospace alloys: Ti6Al4V, Inconel 718/625, 7075 aluminum, 316L stainless, aerospace PEEK
- Documented ability to generate full FAIR, PPAP and batch traceability records
- No active regulatory non-conformance notices or major customer scrap lawsuits in past 3 years
- English-speaking dedicated aerospace engineering and QA team for technical alignment
Pass all items to move forward to full formal qualification. Any unchecked item triggers immediate disqualification for flight-critical part sourcing.

- Cannot provide valid, non-expired AS9100D certification
- Relies solely on uncertified subcontractors for heat treatment or NDT without full oversight
- No formal material traceability system; unable to link finished parts to raw heat lots
- Refuses to generate full AS9102 FAIR reports for first article batches
- Calibration logs for CMM, NDT and CNC equipment expired over 6 months
- High scrap rate (>5%) on past aerospace component runs with no root cause records
- Mixes aerospace-grade raw stock with general industrial alloys in shared storage
- No Level II certified in-house NDT inspectors for crack/porosity testing
- Unable to provide 7+ years secure digital archiving of batch inspection documentation
- Poor facility contamination control (dust, unsegregated scrap, unmarked material bins)
Post-Qualification Continuous Monitoring Checklist
Vendor qualification is not a one-time audit. Schedule quarterly review to maintain approved status:
- Quarterly OTD on-time delivery performance tracking
- Monthly non-conformance & 8D corrective action review
- Annual recertification check for AS9100 and NADCAP accreditations
- Random lot audit: spot-check MTR, FAIR and NDT report completeness
- Bi-annual mini on-site facility walkthrough for contamination control
- Annual full re-qualification audit every 12 months for flight-critical part suppliers
- Customer satisfaction survey with engineering and procurement feedback scoring
FAQ
Is AS9100 enough to qualify an aerospace vendor?
AS9100 is mandatory but not sufficient. Suppliers also need relevant NADCAP accreditation for heat treatment, NDT and surface finishing, plus complete material traceability and FAIR documentation workflows to pass full OEM qualification.
Can a vendor outsource NDT or heat treatment and still stay qualified?
Yes, but all subcontractors must hold matching NADCAP certificates, and the primary vendor must maintain full end-to-end batch traceability linking every special process step to your finished parts.
How long does full aerospace vendor qualification typically take?
Pre-screening and document review takes 1–2 weeks. On-site facility audit, corrective action follow-up and final approval usually completes within 30–45 calendar days for new suppliers.
What documentation must ship with every aerospace batch?
Complete packet including material COA/MTR, heat treatment logs, NDT test reports, full dimensional inspection records and signed batch traceability logs. For first articles, a full AS9102 FAIR packet is required.
Do prototype-only aerospace vendors follow the same qualification checklist?
Yes. Even R&D and NPI prototype hardware requires traceable, auditable records, as test data feeds into formal flight qualification programs later. Looser QA standards for prototypes create program compliance risks down the line.
