NADCAP Accreditation

NADCAP Accreditation

History of NADCAP

Prior to Nadcap, aerospace companies audited their own suppliers to their own process requirements to verify compliance. As the processes that suppliers were providing to their customers were often similar to or identical, the customer requirements were comparable. Consequently, these duplicate audits were redundant and simply added to everyone’s workload, without adding value. For the Aerospace Prime contractors, conducting their own audits similarly meant duplication of effort, redundant audits, unnecessary administration and, ultimately, higher cost for no added value. Then, in November 1989, a US Government/Industry Equal Partners Conference recommended a consensus solution to the duplication of supplier process control system audits and in July 1990, the Performance Review Institute was incorporated to administer the Nadcap program.

 

What is NADCAP?

The National Aerospace and Defence Contractors Accreditation Program (NADCAP) is an industry-managed approach to conformity assessment that brings together technical experts from both Industry and Government to establish requirements for accreditation, accredit Suppliers and define operational program requirements. This results in a standardised approach to quality assurance and a reduction in redundant auditing throughout the Aerospace industry because Prime contractors, Suppliers and Government representatives have joined forces to develop a program that:

• Establishes stringent industry consensus standards that satisfy the requirements of all
participants.
• Replaces routine auditing of Suppliers with one approved through a consensus decision-
making process of members from the user community.
• Conducts more in-depth, technically superior critical process audits.
• Improves Supplier quality throughout industry through stringent requirements.
• Reduces costs through improved standardisation.
• Utilises technically expert auditors to assure process familiarity.
• Provides more frequent audits for Primes, fewer audits for Suppliers.

 

How a NADCAP accreditation works

The Nadcap process typically begins with a notification from a customer to the Supplier that they should attain accreditation, although some companies choose to pursue Nadcap accreditation without prompting.

The Supplier contacts PRI to request the audit, which is scheduled according to the timeframe and content expectations of the Supplier and the customer. An appropriate auditor is assigned. Nadcap auditors typically have over 30 years’ experience in their field and are contracted after a rigorous selection process into which the Primes and Suppliers input.

After the audit, a report is submitted electronically via eAuditNet, the Nadcap audit software program. The Supplier has an opportunity to respond to any non-conformances identified and the report, with responses reviewed by the relevant PRI staff engineer. When the staff engineer is satisfied that the root cause of all non-conformances has been identified and sustaining corrective action has been implemented, the entire report is submitted to the special process task Group. This body of Nadcap subscribing Primes, who are also experts in the special process, verify the conclusion of the staff engineer and approve the audit for certification. At any stage, the staff engineer or Task Group may request more information before progressing the audit to the next stage.

The accreditation for Nadcap is an ongoing activity. Once initial certification has been issued, the next audit is usually automatically scheduled. Initial accreditation is based on a twelve-month cycle. However, the actual period of initial accreditation depends on audit performance.

 

NADCAP Meetings

Nadcap meetings take place three times per year and function as a forum for Nadcap Subscribers and Suppliers to ensure continual improvement in special process and product quality in the aerospace industry. All Nadcap participants are encouraged to attend the meetings to improve their understanding and experience of the Nadcap program. The meetings also provide valuable learning and networking opportunities. The meeting schedule, agendas and minutes are posted at pri-network.org/Nadcap/ in the Nadcap meetings section.
