First article inspection, or FAI, is a formal check that a production-representative part or assembly was made using the intended production process and conforms to the applicable engineering, drawing, specification, and purchase order requirements. In aerospace and similarly regulated manufacturing, FAI is commonly documented in a first article inspection report, often aligned to AS9102. It is evidence that the process has been verified for that configuration; it is not a guarantee that all future parts will be conforming.
FAI is usually performed when a new part is produced, when there is a design revision, or when a material, process, tooling, source, location, or manufacturing method changes enough to affect fit, form, function, or traceability. Some customers also require a full or partial FAI after a long production lapse. The exact trigger is not universal. It depends on the contract, customer flow-downs, internal procedures, and the governing standard or quality plan.
A practical FAI compares the actual manufactured item against the released design and related requirements. Common elements include:
In an AS9102-style process, this information is typically organized into forms covering part number accountability, product accountability, and characteristic accountability. The terminology and format may vary, but the intent is the same: show traceable evidence that the first production run meets the applicable requirements.
FAI is not the same as routine final inspection, receiving inspection, statistical sampling, or in-process inspection. Those controls may still be required after FAI is complete. FAI also does not approve an unstable process, waive future inspection, or eliminate the need for change control.
A completed FAI can become invalid or incomplete if the engineering revision changes, the supplier changes, the process is moved, tooling is replaced, special process sources change, or the inspection data cannot be tied back to the correct configuration. In regulated environments, weak revision control is one of the common failure modes.
FAI rarely lives cleanly in one system. The drawing and revision may come from PLM or document control. The work order and routing may come from ERP or MES. Nonconformances may be handled in QMS. Calibration status may sit in a metrology or maintenance system. Supplier evidence may arrive through a portal or as controlled documents.
Because of that, digital FAI depends heavily on data quality and integration discipline. If part masters, revisions, characteristics, routings, and document links are not controlled, software can make the FAI package faster to assemble but not more trustworthy. Electronic workflows also need appropriate validation, audit trails, access controls, and change control if they are used as quality records.
In brownfield manufacturing, FAI is often digitized in stages rather than through wholesale system replacement. Full replacement of MES, ERP, PLM, QMS, and inspection systems is usually unrealistic in aerospace-grade environments because of qualification burden, validation cost, downtime risk, integration complexity, traceability obligations, and long equipment lifecycles.
A more typical approach is to standardize the FAI process, control the source of truth for drawings and revisions, connect only the data that matters, and preserve traceable records. That does not guarantee customer acceptance or audit outcomes, but it reduces avoidable ambiguity in how the FAI was created, reviewed, and approved.
