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. 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. As of December 2014 , 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.
The 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.
In 1967, Congress created a separate cabinet-level Department of Transportation, which among other things established the Federal Aviation Administration as an agency under the DOT. At the same time, the NTSB was established as an independent agency which absorbed the Bureau of Aviation Safety's responsibilities. However, from 1967 to 1975, the NTSB reported to the DOT for administrative purposes, while conducting investigations into the Federal Aviation Administration, also a DOT agency.
To avoid any conflict, Congress passed the Independent Safety Board Act, and on April 1, 1975, the NTSB became a fully independent federal agency. As of 2015 , the NTSB has investigated over 140,000 aviation incidents and several thousand surface transportation incidents.
Formally, the "National Transportation Safety Board" refers to a five-manager investigative board whose five members are nominated by the President and confirmed by the Senate for five-year terms. No more than three of the five members may be from the same political party. One of the five board members is nominated as the Chairman by the President and then approved by the Senate for a fixed 2-year term; another is designated as vice-chairman and becomes acting chairman when there is no formal chairman. This board is authorized by Congress under Chapter 11, Title 49 of the United States Code to investigate civil aviation, highway, marine, pipeline, and railroad accidents and incidents. This five-member board is authorized to establish and manage separate sub-offices for highway, marine, aviation, railroad, pipeline, and hazardous materials investigations. Collectively, "National Transportation Safety Board", the "Safety Board" or "NTSB" is used to refer to the entire investigative agency established and managed by this five-member board. As of 2017 , Robert Sumwalt is chairman of the NTSB.
Since its creation, the NTSB's primary mission has been "to determine the probable cause of transportation accidents and incidents and to formulate safety recommendations to improve transportation safety (in the USA)". Based on the results of investigations within its jurisdiction, the NTSB issues formal safety recommendations to agencies and institutions with the power to implement those recommendations. The NTSB considers safety recommendations to be its primary tool for preventing future civil transportation accidents. However, the NTSB does not have the authority to enforce its safety recommendations.
The NTSB is the lead agency in the investigation of a civil transportation accident or incident within its sphere. An investigation of a major accident within the United States typically starts with the creation of a "go team," composed of specialists in fields relating to the incident who are rapidly deployed to the incident location. The "go team" can have as few as 3-4 people or as many as a dozen, depending on the nature of the incident. Following the investigation, the agency may then choose to hold public hearings on the issue. Ultimately, it will publish a final report which may include safety recommendations based on its findings. The NTSB has no legal authority to implement or impose its recommendations, which must be implemented by regulators at either the federal or state level or individual transportation companies.
Significant investigations conducted by the NTSB in all modes of transportation in recent years include the collapse of the I-35W 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.
In order to conduct its investigations, the NTSB operates under the "party system", which utilizes the support and participation of industry and labor representatives with expertise specifically useful to its investigation. These individuals or organizations may be invited by the NTSB to become parties to the investigation, and participate under the supervision of the NTSB. The NTSB has discretion over which organizations it allows to participate. Only individuals with relevant technical expertise are allowed to represent an organization in an investigation, and attorneys and insurance investigators are prohibited by law from participating. For example, if an aircraft manufacturer's employee has technical knowledge of the aircraft model involved, he or she may represent the manufacturer in an aircraft investigation.
The NTSB considers the party system crucial to the investigative process, as it provides the NTSB with access to individuals with specialized expertise relevant to a particular investigation. However, use of the party system is not without controversy. The NTSB invited The Boeing Company to participate as a party to the investigation of the crash of TWA Flight 800, a Boeing 747, in 1996. While the NTSB relied on Boeing's sharing of expertise, it was later determined that Boeing had withheld from the NTSB a study of military versions of the 747 that investigated flammable vapor combustion in the center fuel tank. Boeing had told the NTSB that it had no studies proving or disproving the vapor combustion theory. In response to political pressure after the Boeing incident, the NTSB commissioned the nonprofit Rand Corporation to conduct an independent study of the NTSB's aircraft investigation process.
In 2000, Rand published its report, which concluded that the party system is "a key component of the NTSB investigative process" and that participant parties "are uniquely able to provide essential information about aircraft design and manufacture, airline operations, or functioning of [the National Airspace System] that simply cannot be obtained elsewhere".:31 However, Rand also found conflicts of interest inherent in the party system "may, in some instances, threaten the integrity of the NTSB investigative process".:30 The Rand study recommended that the NTSB reduce its reliance on party representatives and make greater use of independent investigators, including from NASA, the Department of Defense, government research laboratories, and universities.:31-32 As of 2014 , the NTSB has not adopted these recommendations and instead continues to rely on the party system.
As of 2014 Starting in 1990, the NTSB has annually published a "Most Wanted List" which highlights safety recommendations that the NTSB believes would provide the most significant -- and sometimes immediate -- benefit to the traveling public., the NTSB has issued about 14,000 safety recommendations in its history, 73 percent of which have been adopted in whole or in part by the entities to which they were directed.
Among transportation safety improvements brought about or inspired by NTSB recommendations:
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 FAA or the Coast Guard. The NTSB employs administrative law judges which initially hear all appeals, and the administrative law judge's ruling may be appealed to the five-member Board. 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. However, the NTSB's determinations will not be overturned by the federal courts unless the NTSB abused its discretion, or its determination is wholly unsupported by the evidence.
The Safety Board maintains a training academy 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, which was recovered from the Atlantic Ocean after it crashed on July 17, 1996, following a fuel tank explosion.
