Quality Control Process
Order Review & Drawing Control
Every order is reviewed against the current engineering drawing revision. No work begins until drawings are confirmed at the correct revision level and all quality clauses are identified and communicated to production.
First Article Inspection (FAI)
First article inspection performed per SAE AS9102. Full balloon drawing, dimensional report, material certifications, and Certificate of Conformance delivered with the FAIR package for new part numbers and engineering changes.
In-Process Inspection
Operators perform in-process checks at critical stages. CMM verification, hand tool measurement, and surface finish checks at defined intervals. Non-conformances are identified, tagged, and dispositioned before proceeding.
Final Inspection & Certification
Final inspection against the drawing before shipment. Certificate of Conformance issued. Calibration records maintained. Complete documentation package available including dimensional data, material certs, and special process certs.
Calibration & Measurement Control
All measurement equipment is tracked, calibrated, and NIST-traceable. Calibration records maintained per AS9100D Clause 7.1.5. Out-of-calibration impact assessments performed as required.
