As9100

AS9000 (1997) Aerospace Basic Quality System Standard
As aerospace suppliers soon found that ISO 9001 (1994) did not address the specific requirements of their customers, including the DoD, NASA, FAA and commercial, aerospace companies including Boeing, Lockheed Martin, Northrop Grumman, GE Aircraft Engines and Pratt & Whitney, they developed AS9000, based on ISO 9001, to provide a specific quality management standard for the aerospace industry.[8]

Prior to the adoption of an aerospace specific quality standard, various corporations typically used ISO 9001 and their own complementary quality documentation/requirements, such as Boeing””s D1-9000 or the automotive Q standard. This created a patchwork of competing requirements that were difficult to enforce and/or comply with. The major American aerospace manufacturers combined their efforts to create a single, unified quality standard, based on ISO 9001:1994, resulting in AS9000. Upon the release of AS9000, companies such as Boeing discontinued use of their previous quality supplements in preference to compliance with AS9000.

AS9100 (1999)
Although AS9000 satisfied immediate needs, it was recognized that OEMs operate globally—a trend that would only increase, so a global standard was needed. The new standardized document, called 9100, was still based on ISO 9001:1994(E), although it was published separately by each country””s aerospace association or standards body (AS9100 in the U.S). AS9100 added 55 aerospace industry specific amplifications and requirements to ISO 9001:1994.[9]

AS9100 Revision A (2001), Model for Quality Assurance in Design, Development, Production, Installation and Servicing
During the rewrite of ISO 9001 for the year 2000 release, the AS group worked closely with the ISO organization. As the year 2000 revision of ISO 9001 incorporated major organizational and philosophical changes, AS9000 underwent a rewrite as well. It was released as AS9100 to the international aerospace industry at the same time as the new version of ISO 9001.

AS9100A is actually two standards references in one publication; Section 1 defines an updated QMS model aligned with the updated ISO 9001:2000 publication while Section 2 defines a legacy model aligned with ISO 9001:1994. Organizations that in year 2001 were operating a QMS based on ISO 9001:1994 were permitted to conform to Section 2 with the expectation that they would then transition their QMS to Section 1.[10][11]
