In Boeing terminology, Escape describes which event?

• A. Defective part leaves the immediate area
• B. The part is quarantined in storage
• C. The part is re-inspected
• D. The flight test is aborted

Answer: (A)

Escape means a defective part has left the immediate area where it should be contained. In Boeing QA terms, this indicates a breach in containment: a nonconforming part has bypassed the local screening or hold point and could proceed to the next stage or be installed, risking the product. Recognizing an escape triggers necessary actions such as containment, traceability, and root-cause investigation to prevent recurrence and protect safety and quality. The other options describe different scenarios: quarantining the part keeps it in a controlled storage area, re-inspection is a check performed on a suspected item, and aborting a flight test is about test execution, not part containment.
