What is the purpose of a First Article Inspection (FAI)?

• A. A comprehensive verification that a new or changed part meets all design specifications before production, ensuring first-time fit and function.
• B. A routine in-process check performed after parts are produced.
• C. A supplier qualification review prior to contract award.
• D. A design review conducted at the concept stage.

Answer: (A)

First Article Inspection confirms that a new or changed part can be produced to the exact design and that the production process used to make it is capable. It involves a thorough check of the first article against the design data package—dimensions, tolerances, materials, finishes, and any special processes—along with verification that the part will fit and function in its intended assembly. The goal is to establish a reliable baseline for the manufacturing process before full-rate production begins, catching design or process issues early so costly rework and field failures are avoided. This is not a routine in-process check performed after parts are already being produced; it’s a one-time, comprehensive validation tied to new or revised parts or processes. It also isn’t about supplier qualification prior to a contract or a design review at the concept stage, which are separate activities in the lifecycle. By verifying first-time fit, form, and function against the design specifications, FAI provides confidence that subsequent parts can be manufactured consistently to spec.
