This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737, 747, and 777 series airplanes, that requires replacement of the seat track fittings on all passenger seats with new, improved fittings. The actions specified by this AD are intended to prevent unrestrained movement of the passenger seats during high forward deceleration of the airplane, which could result in injury to the passengers or crew members during an emergency landing.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
