Aircraft assembly has changed over the years from purely manual to automated processes. Previously, OEMs assembled the individual parts themselves. Now they sub-contract small bench-top through large complex assembly modules, then OEMs assemble these modules into an aircraft. The Aero Structure Assembly (ASA) Task Group addresses all manufacturers in the supply chain regardless of their tier level when performing any type of aircraft assembly details. Inspection programs are also evolving from inspectors signing off on operations to operators performing self-verification.

 
The number of companies involved in aero structure assembly has grown over the years, and the work carried out by the aerospace supply chain has become more complex and intricate. The risks associated with such work are various and significant; product defects can have serious consequences. As a result, there is a need for a rigorous oversight program to assure that outsourced work is being completed in accordance with industry standards and customer requirements.

The Nadcap® Aero Structure Assembly (ASA) accreditation program satisfies this need for compliance validation. The Aero Structure Assembly task group was established in 2017. Today ASA has accredited more than 40 suppliers and is increasing yearly. ASA accredited suppliers are more than doubling each year.
