AS9100 is a widely adopted and standardised quality management system for the aerospace industry. It was, originally, released in October, 1999, by the Society of Automotive Engineers and the European Association of Aerospace Industries.

The standard fully incorporates the entirety of the current version of ISO 9001, while adding additional requirements relating to quality and safety. Major aerospace manufacturers and suppliers worldwide require compliance and/or registration to AS9100 as a condition of doing business with them.
