Title 49 › Subtitle SUBTITLE II— - OTHER GOVERNMENT AGENCIES › Chapter CHAPTER 11— - NATIONAL TRANSPORTATION SAFETY BOARD › Subchapter SUBCHAPTER II— - ORGANIZATION AND ADMINISTRATIVE › § 1117
Within two years after the National Transportation Safety Board Reauthorization Act becomes law, the Board’s Chairman must add a short “methodology” section to any investigation report that includes a recommendation. For each recommendation, the section must briefly explain three things: what accident evidence the Board collected and how it was analyzed for that recommendation; what outside studies, reports, or experts, if any, were used and the safety benefits or effects they showed; and any known examples of regulated companies or groups that acted like the recommendation before it was published. If the Board knows of more than 3 such examples, it can summarize only 3. The methodology is not required when a recommendation only asks someone to share an existing agency best-practices document or an existing rule. The law does not force changes to older recommendations unless the recommendation is a repeat issued on or after enactment. It also must not delay publishing investigation findings, stop urgent recommendations needed to prevent immediate harm, or limit how many examples the Board may consider before issuing a recommendation.
