Performing an Internal Audit to AS9100 and I am going through Suppliers and the AVL. I have discovered where we have been using suppliers that we have not sent a survey or done any sort of Audit on in over Ten Years. Granted, we have been using them and they have been approved the whole 10+ years. My question is this, if we have not had any notable issues withe the Vendor/ Supplier should I be concerned about qualification to an older Standard of AS9100 simply because of the many changes over those 10 years?
