Airworthiness Directives; Boeing Model 777-200 Series Airplanes Equipped With Air Cruisers Evacuation Slide/Rafts

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777-200 series airplanes, that requires modifying the sliding surface of the door 1 left and door 1 right evacuation slide/rafts. This amendment is prompted by a report of injuries to evacuees using the slide/raft to exit the airplane; the evacuees were unable to achieve adequate initial sliding speed and adequate momentum to carry them expeditiously down the slide/raft. The actions specified by this AD are intended to prevent evacuee overload of the slide/rafts, and consequent impeded evacuation and injury to the evacuees.
