Hi, I work for a sub-contract engineering company who is ISO 9001:2008 certified (Transition to 2015 booked for April 2018) but are looking to gain AS 9100D certification. The Aerospace certification is only to satisfy a small percentage of our customers, the others are happy with 9001. As you get ISO 9001:2015 certification by default when you gain AS 9100D certification, can you run a dual level QMS where only the aerospace customers envoke the full AS 9100 system and all other customers orders are processed under an ISO 9001 system (i.e. not requiring all the heavy weight control plans, ITP's, FMEA's etc...). Or would we have to gain totally separate certification for each system and cature the different customer requirements in the scopes of the two different certifications?
