Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 757-200 series airplanes. This proposal would require modifications to the attachment installation of the forward lavatory. This proposal is prompted by a stress analysis report indicating that the forward lavatory could break free from the upper and/or lower attachments during an emergency landing. 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.
