Closed a 737 production quality escape before it reached final assembly
- Situation
- A recurring fastener-hole quality escape on a 737 fuselage section was driving nonconformance tags and rework at final assembly, putting the AS9100 first-article sign-off at risk.
- Task
- Contain the escape and restore first-pass quality without holding the production line, protecting safety and the delivery schedule together.
- Action
- Led the root-cause analysis on the drilling process, tightened the first-article inspection plan and work instructions, and error-proofed the operation with a revised tooling fixture.
- Result
- Cut the defect rate on the affected section by 42 percent, cleared the AS9100 first-article review, and eliminated the recurring rework at final assembly.
