National Transportation Safety Board: More Detail on the Selection Process Could Increase the Understanding of the Most Wanted List of Transportation Safety Improvements, Report to Congressional Committees [Revised March 19, 2020] [open pdf - 3MB]
From the Highlights: "NTSB [National Transportation Safety Board] investigates accidents across all modes of transportation and issues recommendations intended to prevent similar accidents. In 2019, NTSB published its latest Most Wanted List of Transportation Safety Improvements. It identified 10 transportation safety issues with 268 underlying safety recommendations. The National Transportation Safety Board Reauthorization Act of 2018 included a provision for GAO [Government Accountability Office] to examine NTSB's methodology for evaluating and selecting recommendations for inclusion in the Most Wanted List. This report discusses (1) NTSB's methodology for developing its Most Wanted List and (2) how NTSB addressed statutory requirements and how its methodology aligned with components for systematic decision-making, among other objectives."
