AS9100 Elements for distributor

Answer:
If you are already AS9100 certified, these requirements have not changed, so what you were already doing for AS9100 Rev C would be applicable to AS9100 Rev D. In general, configuration management for a broker could be as simple as tracking the revision of the parts you buy and sell so that you know your customer is getting the correct revision of the part they ask for, special requirements, critical items and key characteristics may not be necessary for you as there may not be any identified for the parts and components you sell. Additionally, the regulatory and statutory requirements will differ depending on your location because different countries have d ifferent laws.
One other thing to consider, if you are only acting in a buy and sell capacity, then maybe looking into AS9120 which is for aerospace distributors rather than the entire AS9100 standard.
