scope:

This Standard is primarily intended to apply to new parts, but can also be applied to parts currently in production. The Standard shall be applicable to all production processes that influence the variation of Key Characteristics.

The variation control process begins with product definition, typically an engineering drawing or specification which identifies Key Characteristics and leads to a variation management program for those Key Characteristics. This process may also be used for Producer-identified Key Characteri0stics

Purpose

This Aerospace Standard is designed to drive the improvement of manufacturing processes through adequate planning and effective management of Key Characteristic variation. The Key Characteristic focus is intended to improve confidence for part features whose variation has a significant influence on endproduct form, fit, performance, service life and manufacturability.
