A disclosure is a letter sent when?

• A. A defective part has been sent to the airline customer
• B. An inspection is passed
• C. A design review is completed
• D. A supplier delivers on time

Answer: (A)

A disclosure is the formal communication to a customer about a defect that has been shipped. When a defective part is sent to the airline customer, the disclosure letter documents the issue, includes details like part identification, lot/serial numbers, quantity, and any potential safety impact, and outlines the corrective actions or required actions the customer should take. It ensures traceability, regulatory reporting, and timely remediation, so the customer can respond appropriately and the supplier can manage containment and replacement or repair. The other scenarios—an inspection being passed, a design review completion, or on-time delivery—do not convey a defect or require notifying the customer with corrective action information, so they wouldn’t trigger a disclosure.
