First Article Inspection (FAI) is an authentication method for a manufacturing process. It is a detailed verification and comparison of the product design to the manufactured part. First articles are conducted on detailed, assembly, and sub-assembly parts.
A First Article Inspection Report (FAIR) is the documentation of the FAI that includes the dimensional data of a part in comparison to the design specifications.
There are two different types of first articles:
1. Full or Standard First Article Inspection
2. Partial First Article Inspection or Delta FAI
A Partial FAI/Delta FAI is conducted when isolated changes are made. Such as drawing changes after a change in the part design, or if a previous FAIR recorded nonconformance of characteristics.
For an AS9102 Delta FAI, it should be noted in box 14 on Form 1, with the baseline part number and reason for Partial FAI. Learn more about when a FAI is required.
The AS9102 Standard is a document created by SAE that establishes the baseline requirements for conducting and documenting a first article inspection for the aerospace industry. Whether an AS9102 is required depends on your customer. If your customer has not made any specific FAI requirements, and you are producing parts for the aerospace industry, you may still use AS9102 as a guideline for performing first article inspection.
