Civil Aeronautics Board
The Civil Aeronautics Board (CAB) was an agency of the federal government of the United States that regulated aviation services, including scheduled passenger airline service, and provided air accident investigation. The agency headquarters were in Washington, D.C.
The Civil Aeronautics Authority Act of 1938 formed the Civil Aeronautics Authority. The agency was renamed in 1940, due to a merger with the Air Safety Board. It became an independent agency under Reorganization Plans Nos. III and IV of 1940, effective on June 30, 1940. The Air Safety Board had formed in 1938. Other predecessor agencies include the Aeronautics Branch (1926–1934), the Bureau of Air Commerce (1934-1938), and the Bureau of Air Mail, Interstate Commerce Commission (1934–38).
The first air accident investigation was the one of the Lovettsville air disaster in 1940.
Some duties were transferred to the Federal Aviation Administration in 1958.
The National Transportation Safety Board (NTSB) was established in 1967, taking over air accident investigation duties.
The Airline Deregulation Act of 1978 specified that the CAB would eventually be disestablished. The agency was disestablished on January 1, 1985. The remaining tasks were transferred to the Secretary of Transportation except for a few going to the U.S. Postal Service.
The agency had its headquarters in the Universal Building in Dupont Circle, Washington, D.C. The agency had moved there by May 1959. Previously it had been headquartered in the Commerce Building (a.k.a. the Herbert C. Hoover Building), and its offices were in several buildings. After moving into the Universal Building, CAB leased space there. By 1968 the agency had acquired an additional approximately 2,000 square feet (190 m2) of space in the same building, resulting in additional rent expenses.
