Investigation Reports by Mode


This listing of investigations includes those open investigations involving accidents or incidents which resulted in significant loss of life, physical damage, involve issues of importance to public safety, or which have generated particular public interest. This represents only a small portion of the investigations conducted by the NTSB, most of which occur at the regional level. See this listing of selected regional investigations for more information.

Foreign Investigations

The National Transportation Safety Board (NTSB) is an independent agency of the United States Government responsible for the investigation of transportation accidents. The NTSB participates in the investigation of aviation accidents and serious incidents outside the United States in accordance with the Chicago Convention of the International Civil Aviation Organization (ICAO) and the Standards and Recommended Practices (SARPS) provided in Annex 13 to the Convention.

The Investigative Process

The National Transportation Safety Board was established in 1967 to conduct independent investigations of all civil aviation accidents in the United States and major accidents in the other modes of transportation. It is not part of the Department of Transportation, nor organizationally affiliated with any of DOT's modal agencies, including the Federal Aviation Administration. The Safety Board has no regulatory or enforcement powers.

To ensure that Safety Board investigations focus only on improving transportation safety, the Board's analysis of factual information and its determination of probable cause cannot be entered as evidence in a court of law.
