National Transportation Safety Board

" The NTSB plays a vital role in transportation safety. It is charged with investigating all civil aviation accidents in the United States and selected accidents in other transportation modes, determining the probable cause of these accidents, and making appropriate recommendations, as well as performing safety studies. In 2006, NTSB's reauthorization legislation mandated GAO to annually evaluate its programs. From 2006 to 2008, GAO made 21 recommendations to NTSB aimed at improving management and operations across several areas. Since that time, NTSB has taken action to address all 21 recommendations. Some of these were completed by requiring only a single action, whereas others required continuing effort to achieve operational improvement. For this review, GAO examined the extent to which desired outcomes are being achieved in five areas where continuing effort was necessary. GAO analyzed workforce, financial, and program data, and interviewed agency officials about actions NTSB has taken. "
