NADCAP (National Aerospace and Defense Contractors Accreditation Program) is the globally recognised accreditation for aerospace special processes \u2014 heat treatment, NDT, chemical processing, welding, and composites. A single NADCAP accreditation replaces individual customer audits from dozens of prime contractors, reducing supply chain audit burden and cost for aerospace suppliers who serve multiple OEMs.<\/b><\/p>\n

What Is NADCAP and Why It Exists<\/b><\/h2>\n

Before NADCAP was established in 1990, every major aerospace prime contractor \u2014 Boeing, Lockheed, General Dynamics, McDonnell Douglas, and others \u2014 maintained its own approved supplier list for special processes and sent its own auditors to perform facility audits on every supplier performing heat treatment, plating, NDT, or other critical processes. A heat treatment shop that served five prime contractors would receive five separate sets of auditors, each following slightly different audit checklists, each generating its own audit report and corrective action system, and each requiring the supplier’s quality organisation to manage five separate approval relationships.<\/span><\/p>\n

The redundancy and cost burden of this system was significant on both sides: prime contractors were spending enormous resources auditing the same suppliers repeatedly for the same processes, and suppliers were spending equally large resources hosting audits, responding to different corrective action formats, and maintaining multiple approval databases. NADCAP was the aerospace industry’s collaborative solution: a single neutral third-party audit accepted by all participating prime contractor subscribers, eliminating the need for individual customer process audits.<\/span><\/p>\n

The Performance Review Institute (PRI), a non-profit organisation based in Warrendale, Pennsylvania, administers NADCAP. PRI recruits and trains NADCAP auditors (typically retired aerospace prime contractor quality engineers with deep special process expertise), develops and maintains the audit checklists (called PRI\/NADCAP Audit Criteria or PACs) for each commodity, manages the Merit approval system, and maintains the NADCAP database that prime contractor subscribers access to verify supplier accreditation status.<\/span><\/p>\n
