National Transportation Safety Board

我们是谁，我们做什么
​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ 国家运输安全委员会 是一个独立的联邦机构，由国会负责调查美国的每一起民用航空事故以及其他运输方式（公路、海运、管道和铁路）中的重大事故。

我们确定所调查事故的可能原因，并发布旨在防止未来事故发生的安全建议。此外，我们进行交通安全研究并协调联邦政府和其他组织的资源，以帮助受到重大交通灾难影响的受害者及其家人。

Who We Are and What We Do
​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The National Transportation Safety Board ​is an independent federal agency charged by Congress with investigating every civil aviation accident in the United States and significant accidents in other modes of transportation — highway, marine, pipeline​​, and railroad.

​We determine the probable cause of the accidents we investigate and issue safety recommendations aimed at preventing future accidents. In addition, we conduct transportation safety research and coordinate the resources of the federal government and other organizations to assist victims and their family members​ who have been impacted by major transportation disasters.​
