In the recent past, the shot peening group at Wheelabrator has been approached by several aerospace MRO facilities with request for peening equipment that conforms to Nadcap (National Aerospace and Defense Accreditation Program) audit requirements. To address the importance of this audit to our aerospace customers, this discussion will attempt to explain and highlight how equipment design can satisfy such a critical requirement. If appropriate steps are taken in the design of peening equipment and associated processes, conformance to specifications and audits including Nadcap will be simplified to a routine and effortless task. The need for a unified specification was felt almost 15 years ago resulting in the genesis of Nadcap under SAE and PRI. The current audit criteria are the result of elaborate discussions over the years among various primes such as Boeing, GE Aircraft, Rolls-Royce, etc.
