A First Article Inspection (FAI) package was submitted for a multi-level assembly, intended as a partial or "delta" FAI based on a previous revision. The supplier completed the characteristic data on Form 3 but populated Form 1 with only top-level part information, omitting details about the sub-components.
The incomplete Form 1 failed to list all sub-assembly and detail part numbers (Field 15), their part types (Field 17), and a clear reason for the partial FAI (Field 14). This broke the traceability chain, making it impossible for the customer to verify which components were covered by the FAI and why a full FAI was not performed.
Key Takeaways
- The entire FAI package was rejected for non-compliance with AS9102 requirements.
- The supplier was required to conduct a full data review, correct all three forms, and formally resubmit the package, causing a delay in product acceptance.
- The incomplete Form 1 failed to list all sub-assembly and detail part numbers (Field 15), their part types (Field 17), and a clear reason for the partial FAI (Field 14).
Common Mistakes
- The incomplete Form 1 failed to list all sub-assembly and detail part numbers (Field 15), their part types (Field 17), and a clear reason for the partial FAI (Field 14).
- Missing balloon numbers on the drawing.
- Title block requirements not accounted for on Form 3.
- Incorrect or incomplete Form 1 part number traceability.
Best Practice
Ensure all required and conditionally required fields on AS9102 Form 1 are meticulously completed to establish clear traceability for the part and its subordinate structure. As the "Part Number Accountability" document, an incomplete Form 1 invalidates the integrity of the entire FAI package and will likely result in its rejection.
