What is AS9100?
AS9100D is the quality management standard for aviation, space and defence organisations. It takes ISO 9001 and adds requirements for configuration management, product safety, counterfeit part prevention, first article inspection, risk management and tighter control of suppliers and special processes.
The hard part of AS9100 is traceability over time. An auditor might ask which revision a part was built to, who approved the change and where the first article is. When those answers live in separate folders, the search takes days.
