Summary

The National Transportation Safety Board must investigate every accident that involves civil aircraft. When both military and civil aircraft are involved, the Board must investigate with the appropriate military authorities. A person hired under section 1113(b)(1) who runs an accident investigation or hearing has the same powers as the Board. The Board must make rules about how accidents are reported and who gets notified. The Board must let the Secretary of Transportation join investigations when needed for the Secretary’s duties, but the Secretary cannot help decide probable cause. If only military aircraft are involved and the Secretary’s duties are or might be involved, the military must let the Secretary join. In other military-only accidents, the military should give the Board or the Secretary any information that will help improve air safety.

In subsection (a)(1)(A), the words “and report the facts, conditions, and circumstances related to each accident and the probable cause thereof” in 49 App.:1441(a)(2) are omitted as unnecessary because of section 1131(d) of the revised title. In subsection (a)(1)(B), the words “provide for” in 49 App.:1442(a) are omitted as surplus. In subsection (a)(2), the words “any member of the National Transportation Safety Board or any officer or employee of the National Transportation Safety Board” in 49 App.:1441(c) are omitted as unnecessary because of section 1113 and 1134 of the revised title. In subsections (c) and (d), the words “Secretary of Transportation” and “Secretary” are substituted for “Administrator” in section 701(g) and 702(b) and (c) of the Federal Aviation Act of 1958 (Public Law 85–726, 72 Stat. 782) for consistency. section 6(c)(1) of the Department of Transportation Act (Public Law 89–670, 80 Stat. 938) transferred all duties and powers of the Federal Aviation Agency and the Administrator to the Secretary of Transportation. However, the Secretary was to carry out certain provisions through the Administrator. In addition, various laws enacted since then have vested duties and powers in the Administrator. All provisions of law the Secretary is required to carry out through the Administrator are included in 49:106(g). In subsection (c), the words “and his representatives” in 49 App.:1441(g) are omitted because of 49:322(b). The words “when participation is necessary to carry out the duties and powers” are substituted for “In order to assure the proper discharge . . . of his duties and responsibilities” to eliminate unnecessary words. The words “or his representatives” are omitted because of 49:322(b).
