The Civil Aeronautics Board (CAB) was an agency of the federal government of the United States, formed in 1940 from a split of the Civil Aeronautics Authority[1] and abolished in 1985, that regulated aviation services (including scheduled passenger airline service[2]) and, until the establishment of the National Transportation Safety Board in 1967, conducted air accident investigations. The agency was headquartered in Washington, D.C.
