Action
Final rule.
Summary
This final rule amends the FAA's regulations on the crashworthiness of passenger and flight attendant seats on transport category airplanes used in part 121 passenger-carrying operations. This final rule requires those transport category airplanes type- certificated after January 1, 1958 which have not yet been manufactured that are used in part 121 passenger-carrying operations to have passenger and flight attendant seats that meet the current improved crashworthiness standards. This action is necessary because research, accident data, and analysis show that these improvements provide increased occupant protection in airplanes involved in impact- survivable accidents.
