First Article Inspection (FAI)

A documented verification that initial production output meets the applicable design and specification requirements.

Definition and context

First Article Inspection checks initial production output against applicable design requirements. Agree the required scope and documentation before inspection. A first-piece setup check is not automatically equivalent to a formal FAI.

What happens during an FAI

Verify all characteristics required by the applicable FAI procedure, including dimensions, material evidence and relevant test results. Do not limit a formal FAI to only the dimensions labelled critical.

Any deviation is documented and dispositioned before the supplier receives authorization to proceed.

Collaborating with suppliers

Suppliers prepare detailed inspection reports, photographs, and supporting certificates.

Buyers often require accompanying certificates of conformity to complete the approval package.

Where this term fits in the workflow
