Aerospace Series - Quality Management Systems - Variation Management of Key Characteristics

This standard is primarily intended to apply to new parts and products intended to be produced in an on-going production phase, but can also be applied to parts currently in production (e.g., manufacturing, maintenance). The standard is applicable to all production processes that influence the variation of KCs, as well as maintenance and service processes in which KCs are identified. It applies to organizations for assemblies and all levels of parts within an assembly, down to the basic materials including castings and forgings, and to organizations that are responsible for producing the design characteristics of the product. The variation control process begins with product definition, typically stated in the design documentation (e.g., digital model, engineering drawing, specification) which identifies KCs, and leads to a variation management process for those KCs. This process may also be used for producer-identified KCs (e.g., process KCs, additional/substitute product KCs). Producers and their subcontractors are responsible for flow down of the standard requirements to those external providers, who produce design characteristics and provide production and service provisions, to ensure that KCs conform to the customer’s requirements. This standard was revised to align with the latest revisions of the International Aerospace Quality Group (IAQG) standards (i.e., 9100, 9110, 9102, 9138, 9145) and to incorporate industry feedback. Other changes made to standard requirements presented herein were editorial in nature for increased clarity, including additional terms and definitions, and references to other relevant external standards.
