AS9100 is the internationally recognized quality management system standard for aviation, space, and defense organizations. The current published edition is AS9100 Rev D, aligned with IAQG 9100:2016 and built on ISO 9001:2015. It keeps ISO 9001’s quality management foundation and adds aerospace controls for product safety, operational risk, configuration management, supplier oversight, counterfeit-part prevention, and traceability.
Those controls are one part of a much larger safety system that also includes engineering, regulation, maintenance, training, and accident investigation. The results are striking: IATA recorded 51 accidents across 38.7 million flights in 2025, while an MIT analysis estimated one fatality per 13.7 million passenger boardings from 2018 through 2022.
