Nadcap Certification

National Aerospace and Defense Contractors Accreditation Program


nadcap-internal.jpgNadcap is a global cooperative accreditation program for aerospace engineering, defense, and related industries. It is administered by the “Performance Review Institute (PRI).” PRI’s goal is to ensure that aircraft and aero engines are of the highest quality to ultimately protect the public. Before Nadcap, the responsibility for assuring subcontractor quality was shouldered by the individual aerospace companies. Nadcap is a user friendly tool that assists the industry by eliminating duplication of efforts, inconsistent applications of standards and unnecessary costs associated with redundant audits.

  • Nadcap establishes stringent industry standards that satisfy the requirements of all participants
  • Reduces routine special process audits
  • Conducts more in-depth technical audits
  • Improves supplier quality through stringent requirements
  • Reduces costs through improved standardization
  • Utilizes industry specific technical auditors
  • Unimetal’s NADCAP passivation processes meets the standards for ASTM A967, SAE AMS 2700 & SAE AMS QQ-P-35


The Society of Automotive Engineers (SAE) created Nadcap in 1990. Nadcaps membership of prime contractors conveys industry standards for special processes and products. The organizations mission is to provide national and international unbiased independent processing, product assessments and certification services for the purpose of adding value, reducing total costs and facilitating relationships between aerospace and defense buyers and Nadcap suppliers.
