Abstract: NADCAP project is the process certification of special process production in the supply system of aerospace industry, and is the basis of cooperation with international well-known aviation enterprises. Based on the practical experience of Beijing Institute of Aeronautics and materials in the process of NADCAP certification, this paper shares the personal opinions and experience on the key points of AMS2750E certification, the summary and cause analysis of errors prone to be made in the audit, and the implementation process of corrective measures for nonconformities.

Key words: NADCAP, AMS2750E, pyrometry, corrective actions for nonconformities
