The National Transportation Safety Board (NTSB) is an independent U.S. government agency established on April 1, 1967, as part of the Department of Transportation (DOT). However, it was reestablished as a separate entity in 1974 to ensure its independence from other federal agencies[2][4]. The NTSB is responsible for investigating accidents in various transportation modes, including aviation, highway, marine, railroad, pipeline, and hazardous materials. It has no regulatory authority but focuses on conducting forensic investigations and proposing safety recommendations[3][5]. Notable roles of the NTSB include determining the probable cause of accidents and releasing safety recommendations to prevent future incidents. Since its inception, the NTSB has made over 14,500 safety recommendations, with more than 80% being implemented, leading to significant reductions in fatalities across different transportation sectors[1][5]. The agency also maintains a database of U.S. civil aviation accidents and provides investigators for international aviation accidents involving U.S.-registered aircraft[5]. Key achievements of the NTSB include the implementation of numerous safety measures that have saved countless lives. The agency's independence allows it to conduct unbiased investigations, which has been crucial in addressing systemic safety issues in the transportation industry[3]. The NTSB's work extends beyond accident investigations; it also engages in public awareness campaigns to disseminate safety information broadly[5]. Currently, the NTSB remains highly relevant in ensuring transportation safety. It continues to investigate significant accidents and issues recommendations to improve safety standards across various modes of transportation. The agency's independence and focus on safety have made it a model for systemic risk management in other industries[3]. Recent events have highlighted the NTSB's ongoing role in investigating contemporary transportation incidents and advocating for enhanced safety measures[7].
