Title 49 › 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 any investigative report that includes a Board recommendation. For each recommendation, that section must say, in plain terms, the investigation facts and analysis most relevant to the recommendation; what outside information (like studies, reports, or experts) was used and what safety benefits or effects those sources showed; and a brief list of any known actions taken by regulated entities before the recommendation that matched it. If the Board knows of more than 3 such prior examples, it may limit the list to 3. The requirement does not apply when the recommendation only tells someone to share an existing agency best-practices document or an existing regulatory rule. It does not force changes to recommendations made before enactment unless the recommendation is a repeat issued on or after that date. It also must not delay publishing investigation findings, stop urgent recommendations needed to prevent immediate harm, or limit how many examples the Board can consider before issuing a recommendation.
