The NTSB issued a notice of proposed rulemaking seeking public comment regarding proposed changes to rules governing investigation procedures. It is proposing to organize investigation procedures into mode-specific subparts to make the rules easier to access and consult. The NTSB also proposed updating “some terms and procedures,” including using “event” to describe transportation mishaps in regulatory text. In addition, the NTSB proposed making changes to its procedures for allowing investigative party participants to share information for the “purposes of making timely safety improvements.” Comments are due by October 14.
