Active Standard: D4066 - 13
It has been brought to the attention of ASTM that the aerospace industry has a critical need for the existence of D4066 as an active standard. D4066 is needed because it is a part of aircraft product definition data and is called out in thousands of drawings, specifications, and part standards. In November 2012, D4066 was withdrawn and replaced by D6779. However, there are some Groups/Classes/Grades in ASTM D4066 that refer to different materials in ASTM D6779. This can result in confusion within the aerospace supply chain, disruption in the supply of required parts, and impacts to part quality and aircraft safety. The aerospace industry requires consistency and traceability from the final part configuration back to the raw materials that are used to manufacture the part. Because of the withdrawal of D4066, industry OEMs, suppliers, and customers are now burdened with the review and evaluation of all of the affected engineering data unless D4066 is restored.
