Supplier quality escape

A supplier quality escape is a supplier-originated nonconformance that reaches the customer or next operation.

A supplier quality escape is a nonconforming part, material, document, or process output from a supplier that passes through the supplier’s controls and reaches the customer, receiving organization, or next tier of production.

In manufacturing and regulated supply chains, the term is commonly used in supplier quality, receiving inspection, nonconformance management, and corrective action workflows. An escape may involve a dimensional defect, incorrect material certification, missing traceability, wrong revision level, packaging damage, or another requirement that was not detected before shipment.

A supplier quality escape is not the same as any supplier issue. It specifically refers to a quality or documentation problem that was not contained before transfer. It may lead to activities such as containment, lot trace review, nonconformance reporting, supplier corrective action requests, or 8D/RCCA investigation, depending on the organization’s procedures and the nature of the issue.

FAI verifies that a part or assembly, usually from the first production run, conforms to design and specification requirements before routine production acceptance. In-process inspection checks selected characteristics during production to control the process. They are related, but they are not substitutes.

When is a full FAI required?

A full FAI is typically required when there is no valid baseline FAI for the part in its current design, manufacturing source, and production method. Many later changes only require a partial FAI, but customer requirements, AS9102 interpretation, and change impact determine the boundary.

What is first article inspection (FAI)?

First article inspection is a formal verification that a production-representative part or assembly was made using the planned production process and meets the applicable design requirements. It is not a one-time quality guarantee; its scope and triggers depend on customer requirements, revisions, process changes, and standards such as AS9102.

Can the first article be produced on prototype equipment, or must it use production machinery?

Usually, the first article should be made using the approved production-intent process, including the equipment, tooling, planning, and controls that will be used for normal production. Prototype equipment is risky unless the customer or program explicitly accepts it and any later production-equipment change is addressed through FAI and change control.
