The National Transportation Safety Board (NTSB) 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.[2] When requested, the NTSB will assist the military and foreign governments with accident investigation.[2] The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. Deborah Hersman was appointed as NTSB Chairman in July 2009.[3] Christopher A. Hart was designated Vice Chairman on August 18, 2009 for a two-year term. He then became Acting Chairman after Hersman stepped down. The agency is based in Washington, D.C. As of 2013, it has four regional offices around the country and runs a training center in Ashburn, Virginia.[4]

The origin of the NTSB was in the United States Code.[6] It has investigated over 140,000 aviation incidents since its establishment.


The board has five members nominated by the President and confirmed by the Senate for five-year terms, one of whom is nominated as the Chairman by the President and then approved by the Senate for a fixed 2-year term. Another member is designated as vice-chairman and becomes acting chairman when there is no formal chairman.[1]

No more than three of the five members can be from the same political party.[7]

Organization within the Board is composed of separate sub-offices for highway safety, maritime safety, aviation safety, railroad, pipeline, and hazardous materials investigations, research and engineering, communications, and administrative law judges. These sub-offices report to the Office of the Managing Director.


The NTSB is normally the lead organization in the investigation of a transportation accident within its sphere. However, this power can be surrendered to other organizations if the Attorney General declares the case to be linked to an intentional criminal act, although the NTSB would still provide technical support in such investigations. This occurred during the investigation of the September 11, 2001, attacks when the Department of Justice took over the investigation.[8]

In addition, the NTSB has assisted the National Aeronautics and Space Administration (NASA) in its investigations of both the Challenger and the Columbia space shuttle disasters; assisted the Department of Justice during the September 11, 2001, terrorist attack investigations; and assisted the U.S. military in its investigation of the aircraft that crashed in the former Yugoslavia that took the lives of more than 30 Americans, including Commerce Secretary Ron Brown.

Significant investigations conducted by the NTSB in all modes of transportation in recent years include the collapse of the I-35 highway bridge in Minneapolis, Minnesota; the collision between two transit trains in Washington, D.C.; the pipeline explosion that destroyed much of a neighborhood in San Bruno, California; the sinking of an amphibious vessel in Philadelphia; and the crash of a regional airliner near Buffalo, New York.

Since 1990 the NTSB has maintained a Most Wanted List of Transportation Safety Improvements, in which it highlights those recommendations that would provide the most significant — and sometimes immediate — benefit to the traveling public. The Board conducts a press conference every year to announce changes to that list.

Alcohol and drug testing in all modes of transportation.
Excavation damage protection, pipe corrosion protection, and remote shutoff valves.
Recreational boating safety, improved fire safety on cruise ships, and lifesaving devices on fishing vessels.
Positive train control (anti-collision technology), improved emergency exits for passenger rail cars, and shelf-couplers for hazardous material rail cars.
Graduated drivers license laws for young drivers, age-21 drinking laws, smart airbag technology, rear high-mounted brake lights, commercial drivers licenses, and improved school bus construction standards.
Mid-air collision avoidance technology, ground proximity warning systems, airborne wind shear detection and alert systems, smoke detectors in lavatories, floor-level escape lighting, and fuel tank inerting.

Among transportation safety improvements brought about or inspired by NTSB recommendations:

The Board's most important product is the safety recommendation. The NTSB has issued about 13,000 safety recommendations in its history, the vast majority of which have been adopted in whole or in part by the entities to which they were directed.


The Safety Board maintains a training academy[10] in Ashburn, Virginia, where it conducts courses for its employees and professionals in other government agencies, foreign governments or private companies, in areas such as general accident investigation, specific elements of investigations like survival factors or human performance, or related matters like family affairs or media relations. The facility houses for training purposes the reconstruction of more than 90 feet of the TWA Flight 800 Boeing 747,[11] which was recovered from the Atlantic Ocean after it crashed on July 17, 1996, following a fuel tank explosion.

A little-known responsibility of the NTSB is that it serves as a court of appeals for airmen, aircraft mechanics, certificated aviation-related companies and mariners who have their licenses suspended or revoked by the federal government. The Board's determinations may be appealed to the federal court system by the losing party, whether it is the individual or company, on the one hand, or the FAA or the Coast Guard, on the other.

The NTSB's authority to investigate other transportation accidents varies by mode. For example, it investigates highway accidents "in cooperation with the States." For marine investigations, jurisdiction between the NTSB and the U.S. Coast Guard is prescribed in a detailed Memorandum of Understanding between the two agencies. For those railroad and pipeline accidents it chooses to investigate, it has primacy.

The NTSB will also on occasion provide technical and other advice to transportation investigative boards in countries that do not have the equipment or specialized technicians available to undertake all aspects of a complex investigation.

The NTSB may assist in incident or accident investigations occurring outside the United States under certain circumstances. These may include accidents or incidents involving American-registered or American-owned civil aircraft or aircraft with U.S. manufactured components in foreign air space.

The NTSB has primacy in investigating every civil aviation accident in the United States (the Federal Aviation Administration (FAA) is always a party to these investigations, but the NTSB is the investigating agency). For certain accidents, due to resource limitations, the Board will ask the FAA to collect the factual information at the scene of the accident; the NTSB bases its report on that information.
