Aerospace Engine Supplier Quality (AESQ) Consortium™

AESQ Zero Defects

In 2012, top executives from Rolls-Royce, Pratt & Whitney, GE Aviation, and Safran tasked their senior quality executives to work collectively to drive rapid change throughout the aerospace engine supply chain.  The group subsequently formed the G-22 Technical Committee in 2013 and the Aerospace Engine Supplier Quality (AESQ) Consortium™ in 2015 to collaboratively create uniform standards and deploy and support these common supplier requirements.
