Frequently Asked Questions

What is the difference between FAI and PPAP?

FAI is typically used across various industries to verify that production methods can consistently meet design specifications. PPAP, prevalent in the automotive sector, is more comprehensive, involving documentation intended to demonstrate the supplier’s ability to meet client demands consistently.

What is the difference between FAI and FAIR?

FAI, or First Article Inspection, is a process used to validate parts and assembly processes at the start of production. FAIR, which stands for First Article Inspection Report, is the documentation resulting from an FAI. It provides a detailed record of the inspection and its findings, confirming that the part has been produced according to design standards and specifications. Essentially, while FAI refers to the actual inspection process, FAIR is the report that documents the outcomes of this process.
