## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 757-200 and -300 series airplanes, that requires modification of the slide/raft evacuation system by installing a girt reinforcement chafing patch. This amendment is prompted by reports of holes in the inflatable area of the slide/raft evacuation system due to chafing against the installation support bracket. The actions specified by this AD are intended to prevent holes in the inflatable portion of the slide/raft evacuation system, which could result in the slide/raft being less effective as a raft during an emergency water landing.
