Title 49 › Subtitle SUBTITLE II— OTHER GOVERNMENT AGENCIES › Chapter 11— NATIONAL TRANSPORTATION SAFETY BOARD › Subchapter II— ORGANIZATION AND ADMINISTRATIVE › § 1117
Within 2 years after the date of enactment of the National Transportation Safety Board Reauthorization Act, the Chairman must add a short methodology section to every investigative report that includes a Board recommendation. The methodology must explain how the Board picked each recommendation and must say: what accident evidence was most relevant, what outside studies, reports, or experts (if any) were used and what safety effects they showed, and any known examples of regulated companies or groups that already took similar actions before the recommendation. If there are more than 3 known examples, the summary may list only 3. The methodology is not required when a recommendation only asks someone to share an existing agency best practices paper or an existing rule. Nothing forces changes to recommendations made before the date of enactment of the National Transportation Safety Board Reauthorization Act unless the recommendation is a repeat issued on or after that date. The rule must not delay releasing investigation findings or probable cause, must not delay urgent recommendations needed to prevent immediate harm, and does not limit how many examples the Board may consider before issuing a recommendation.
