What is first article inspection?

First Article Inspection (FAI) is a quality control process used in manufacturing to verify that a new or modified production process produces parts that meet all specified requirements. During FAI, the first item produced is thoroughly examined and measured against design specifications, drawings, and other requirements. This inspection helps identify problems early in the production process, ensuring that future items will consistently meet quality standards. FAI is commonly used in industries such as aerospace, automotive, and electronics.
