A First Article Inspection Report (FAIR) is being prepared for an assembly or a complex part derived from a pre-existing item. The supplier needs to correctly account for all subordinate parts, modified items, and starting materials within the FAI package to demonstrate full product conformity.
There is frequent confusion regarding the correct placement of 'make-from' parts versus raw materials within the AS9102 forms. Starting materials or blanks are often incorrectly listed in the Form 1 Part Number Index (Fields 15-18), which is reserved for items on the engineering bill of materials.
Key Takeaways
- This misclassification leads to FAIR rejections, as it fails to provide clear traceability for the product's bill of materials versus its manufacturing process inputs.
- Reviewers cannot easily verify raw material certifications or link to FAIs for subordinate parts when items are documented in the wrong section.
- There is frequent confusion regarding the correct placement of 'make-from' parts versus raw materials within the AS9102 forms.
Best Practice
Ensure the AS9102 Form 1 Part Number Index is used exclusively for items on the product's Bill of Materials, such as detail parts, sub-assemblies, and standard hardware. Raw materials and starting stock must be documented on Form 2, while the FAIR for any prerequisite 'make-from' part number should be referenced by its identifier in Field 18 of the final part's Form 1.
