AS9100 certification in Seattle at a glance
Walk the Duwamish corridor and the aerospace supply chain is visible from the street. The City of Seattle counts more than 6,000 aerospace jobs in the Greater Duwamish Manufacturing and Industrial Center, which also contains Boeing Field, and nearby fabricators, finishers, electronics shops and machine shops answer to the quality terms that aircraft programmes send down. AS9100 is the answer most of them reach for. It takes ISO 9001 as its base, then adds configuration management, product safety, counterfeit-part prevention, risk management of delivery and control of special processes. One recognised certificate replaces separate customer audits. Sterling builds the system with Seattle suppliers from its New York office, and an accredited certification body audits before any certificate is issued.

AS9100 in Seattle: questions clients ask
Why do Duwamish-area suppliers so often ask about AS9100?
Because the area contains Boeing Field and more than 6,000 aerospace jobs by the City's count, so many shops sell, directly or indirectly, to aircraft programmes whose supplier terms require an aerospace quality system. Read the purchase conditions to see exactly what the customer expects.
Is AS9100 audited differently from ISO 9001?
The audit follows the same pattern, but the auditor tests extra aerospace requirements such as configuration management, product safety, counterfeit-part prevention and special-process control, and results are recorded in an industry database. A Seattle shop should rehearse these topics before the certification audit.
