European auditor Martin Bridge explains: “I was attracted to Nadcap auditing because it allows me to control my working hours. The work is technically interesting and varied, and all the companies that I visit are different. I enjoy the opportunity to travel and improve my foreign language skills, although it’s also nice to be able to carry out audits closer to home.”
During a heat-treatment audit, the Nadcap auditor, who is on-site for an average of four days depending on the scope of the audit, conducts 10 job audits. The auditor will review two completed jobs all the way through, including test results and four in-process jobs that will be witnessed during the audit. A compliance job is a step-by-step review of processing on actual hardware. The auditor will also review all pyrometry records and procedures and, if possible, witness a temperature-uniformity survey or a systems-accuracy test.
Gregory Lobsoky, president of California-based Metallurgical Testing Corporation, states: “The Nadcap auditors who visited my facility are among the most competent I have seen. They were professional and objective.”
To ensure special process quality throughout the aerospace industry, subscribing primes are invited to pursue NUCAP (Nad-cap Users Compliance and Audit Program) approval to demonstrate their compliance. In 2006, Honeywell Aerospace, EADS CASA, Rolls-Royce Corporation and Alenia Aeronautica SpA underwent NUCAP heat-treatment audits. Jon Biddulph of Rolls-Royce plc and NUCAP chairperson explains: “NUCAP enables prime subscribers to demonstrate the same level of special process compliance expected from suppliers and subcontractors.”
Heat-treatment accreditation is currently mandated for suppliers based in the sectors indicated for the following major aerospace companies given in Table 1.
Development OpportunitiesTo complement the Nadcap program, PRI offers several development opportunities. These training courses take place worldwide in multiple languages, including English, French, Chinese and Japanese (Table 2).
Nadcap Customer Support Initiative - NCSINCSI is a free training program to aid suppliers with their pre-audit preparation and post-audit non-conformance resolution.
Data from 2006 shows that heat-treatment suppliers who attend this training incur half the number of nonconformities compared to heat-treatment suppliers that do not participate. Nigel Picken, manager of supplier quality and special processes for Rolls-Royce plc, states: “NCSI is an excellent training tool for new suppliers.”
Root Cause Corrective Action - RCCAThe Demming Study on Errors showed that 94% of errors are process-related, while only 6% are people-related. This seminar is based on the flow chart used by Nadcap and provides a method for participants to use to improve root-cause analysis and prevent the same mistakes from occurring again (Fig. 1).
On average, data has shown that course participants perform 30% better on their audits than those who do not participate. After participating in a RCCA course, suppliers close out their audits on average 25% faster than before they participated in this training.
Introduction to PyrometryThe objectives of this training course are to ensure that participants gain a thorough understanding of how to implement the requirements of AMS2750D within their facilities. Topics include: temperature sensors, instrumentation, classification of furnaces, system accuracy tests and temperature uniformity tests.
Internal AuditingInternal auditing is a new training class for 2007 that was created in response to feedback from other course participants. Attendees receive an overview of the audit process, learn how to select qualified internal auditors, practice interviewing techniques and develop an audit plan and checklist for their company. They also learn about internal-auditing requirements and how the results can improve their business.
Quality 101Quality training for the non-quality engineer is an overview of quality terms for those new to the field. These include: What is an audit vs. a job audit?; What are nonconformances?; What are root causes?; and much more. This course aims to provide participants with a good understanding of why quality is important, the concepts of Total Quality Management (TQM) and process improvement, and the ability to understand and use quality tools. This course has been designed for new employees or any manufacturing personnel that requires a common competency or awareness of basic quality concepts. IH
