## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 767-200, -300, and -400ER series airplanes. The existing AD currently requires an inspection to determine if the door-mounted escape slide/rafts have certain part numbers. For those door-mounted escape slide/rafts having certain part numbers, the existing AD also currently requires an inspection for excessive tension of the firing cable, and procedures for providing slack in the firing cable or rerouting the firing cable if necessary. For certain airplanes, this proposed AD would require a review of the airplane maintenance records to determine if a certain service bulletin has been incorporated, or an inspection to determine if certain door-mounted escape slide/rafts are installed. This proposed AD would also require modification of certain escape slide/rafts. This proposed AD results from reports of uncommanded inflation inside the airplane of a door-mounted escape slide/raft located in the passenger compartment. We are proposing this AD to prevent injury to maintenance personnel, passengers, and crew during otherwise normal operating conditions and to prevent interference with evacuation of the airplane during an emergency, due to uncommanded inflation of a door-mounted escape slide/ raft.
