Summary
This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Boeing Model 757-200 series airplanes, that currently requires modifications to the attachment installation of the forward lavatory. This action would add airplanes to the applicability of the existing AD. The actions specified by the proposed AD are intended to prevent failure of the attachment installation of the forward lavatory during an emergency landing, which could result in injury to the crew and passengers. This action is intended to address the identified unsafe condition.
