Boeing Model 767 Series Airplanes Equipped with Over-Wing Escape Slides
Model 767 series airplanes, having line positions 1 through 542 inclusive, and equipped with over-wing escape slides; certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes equipped with over-wing escape slides, that currently requires modification of the trailing edge panels and the aft flaps. That amendment was prompted by the results of functional tests of over-wing escape slides, which revealed that some slides were damaged when they were deployed across sharp corners on the trailing edge of the wing and the large gaps between the trailing edge panels of the wing. This amendment expands the applicability of the existing AD to include additional airplanes. The actions specified by this AD are intended to prevent damage to the over-wing escape slide, which could hinder inflation of the slide to a usable configuration during an emergency evacuation.
