Summary
This document proposes the supersedure of 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 AD 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 action would expand the applicability of the existing AD to include additional airplanes. The actions specified by the proposed 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.
