FAI rejection is the disposition of a first article inspection submission as not accepted due to missing, incorrect, or nonconforming evidence.
FAI rejection commonly refers to a first article inspection submission being formally found unacceptable for approval because required information, objective evidence, or product results do not meet the applicable first article requirements.
In aerospace and other regulated manufacturing, this usually relates to a First Article Inspection (FAI) package or report, not just the physical part by itself. A rejection can result from dimensional nonconformities, incomplete documentation, missing material or process certifications, incorrect drawing accountability, characteristic traceability gaps, or errors in how the FAI was prepared and submitted.
An FAI rejection does not automatically mean the product is unusable, scrapped, or permanently disqualified. It means the submitted first article evidence was not accepted in its current state. Follow-on actions may include correction, reinspection, partial or full repeat FAI activity, nonconformance processing, or resubmission, depending on the reason for rejection and the organization’s quality process.
In day-to-day workflows, an FAI rejection often appears as a status in a quality system, FAI software platform, supplier portal, or customer review process. It may block part approval, shipment, supplier release, or progression to regular production until the rejected items are resolved and the required evidence is accepted.
Typical data tied to an FAI rejection can include the part number, drawing revision, serial or lot reference, characteristic numbers, measurement results, accountable forms, and the stated reason for rejection.
FAI rejection is often confused with first pass yield failure, NCR rejection, or lot rejection. These are related but different. An FAI rejection concerns first article acceptance and its evidence package. An NCR addresses a documented nonconformance. A lot rejection applies to production quantity acceptance. One event can trigger another, but the terms are not interchangeable.
It is also commonly confused with partial FAI. A partial FAI is a scoped first article activity for a defined change. It is not itself a rejection status, although a partial FAI submission can also be rejected.
In aerospace practice, FAI rejection is commonly discussed in connection with AS9102-based first article processes. The term describes an acceptance outcome within that workflow rather than a separate standard or standalone quality method.
