First article inspection checklist: what to measure before you approve production

A first article inspection checklist is the gate between tooling and volume. It proves production parts match the released drawing, materials, and process before you approve the run.

A first article inspection checklist is a structured list of design characteristics, materials, and process evidence you verify on the first parts built with production intent. The point is not to admire a pretty sample. The point is to prove the process can make conforming parts before volume shipping starts.

Aerospace and defense programs often formalize FAI under IAQG 9102 / AS9102. Consumer and industrial products may not need AS9102 forms, but they still need the same discipline: account for every critical characteristic, record measured results, and tie the part to a known revision of drawings, BOM, and process.

For the surrounding path from prototype into manufacturing, see invention prototype to production and prototype to production steps.

First article inspection is a documented verification that the first parts from a production-capable process conform to the approved design. In practice that means:

NIST work on the Quality Information Framework (QIF) treats inspection results as structured data that can feed first article reports, which is useful context when teams want digital traceability rather than only paper forms (NIST publication on FAIR generation from QIF).

Run a first article when any of these are true:

Do not treat a successful prototype as an FAI. Prototypes are often printed, machined, hand-finished, or assembled by the people who designed them. They answer risk questions. They do not prove that a different operator, tool, and process will hold the drawing.

If the design is still moving, finish design for manufacturing review and freeze the release package before paying for a formal first article. Measuring an obsolete revision wastes schedule.

Use this table as a working first article inspection checklist. Adjust depth to product risk (consumer accessory vs industrial assembly vs customer-mandated AS9102).

For aviation, space, and defense programs, map these rows to the customer's AS9102 form set and the planning guidance summarized in the IAQG 9102 FAQ. For commercial products, keep the same evidence even if you use a simpler sheet.

Self-inspection by the person who made the feature is a weak control. Prefer an independent checker and, where practical, measurement equipment that is not the same machine that cut the part.

A dimensional pass with the wrong resin or an unapproved plating source is still a failed first article. Attach:

If your customer uses digital product definition without a complete 2D drawing, extract the characteristics required to manufacture and inspect the part, then verify those extracted requirements. IAQG guidance expects that discipline for DPD-driven products.

Inspection criteria and a golden sample belong on the pre-production checklist in invention prototype to production. The FAI report is the evidence package; the golden sample is the shared physical truth for cosmetics and feel.

Quiet line fixes without revision control create the next field failure. Change control is part of a workable design control process, even on non-medical products.

LA NPDT is a Louisiana product development firm (Ruston / statewide; not Los Angeles). On programs that reach manufacturing handoff, the useful work is releasing a package a factory can build and inspect: production-intent CAD, drawings, BOM, DFM notes, and a clear first article plan. Related services include low-volume manufacturing and the production-intent checks in enclosure design for electronics.
