About Us

For more than six decades, the Coordinating Agency for Supplier Evaluation (C.A.S.E.) has been the aviation industry’s trusted standard for supplier oversight, audit consistency, and shared compliance data. Established in 1963 and strengthened by the formation of the Air Carrier Section in 1982, C.A.S.E. has grown into the most recognized collaborative audit model in U.S. commercial aviation. Major carriers such as Northwest, US‑Air, United, TWA, and FedEx helped build the foundation we operate on today. The FAA recognizes C.A.S.E. and its shared audit methodology as an accepted means of compliance with 14 CFR 121.373 and 135.431, supported through Operations Specification D‑90. That level of regulatory confidence is one of the many reasons the industry continues to rely on us.
