NTSB The National Transportation Safety Board is an independent U.S. government investigative agency responsible for civil transportation accident investigation.

In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, and railroad accidents. When requested, the NTSB will assist the military and foreign governments with accident investigation. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C., it has four regional offices located in Anchorage, Alaska; Denver, Colorado; Ashburn, Virginia; and Seattle, Washington. The agency also operates a national training center at its Ashburn facility.HistoryThe origin of the NTSB was in the Air Commerce Act of 1926, which assigned the United States Department of Commerce responsibility for investigating domestic aviation accidents. The USA's first "independent" Air Safety Board was established in 1938: it lasted only fourteen months. In 1940, this authority was transferred to the Civil Aeronautics Board's newly formed Bureau of Aviation Safety.
