A supplier submitted a First Article Inspection Report (FAIR) for a complex assembly containing multiple sub-components produced to separate drawings. The assembly-level FAIR correctly documented the final assembly characteristics but did not include or reference the individual FAIRs for the detail parts.
The submittal was rejected as incomplete because the AS9102 standard requires that every unique part number within an assembly has its own full or partial FAIR. The assembly-level FAIR must act as an index, accounting for the verification of all child components within the bill of materials.
Key Takeaways
- The FAIR deliverable was delayed while the supplier generated and compiled the missing detail part FAIRs.
- This rework required additional quality engineering resources to complete and properly index all documentation within the final assembly-level FAIR package.
- The submittal was rejected as incomplete because the AS9102 standard requires that every unique part number within an assembly has its own full or partial FAIR.
Common Mistakes
- The submittal was rejected as incomplete because the AS9102 standard requires that every unique part number within an assembly has its own full or partial FAIR.
- 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
Organizations must ensure that an assembly-level First Article Inspection plan explicitly includes the generation and indexing of separate FAIRs for every detail part and sub-assembly. The top-level assembly FAIR is not a substitute for component-level verification and must demonstrate traceability to the compliant FAI for each constituent part.
