Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 757-200 series airplanes with stowage bins installed forward of door 2 at Station 680. This proposal would require a one-time inspection to determine if a certain intercostal is installed for support of the overhead stowage bin(s) at Station 680, and follow-on actions, if necessary. This action is necessary to prevent failure of the stowage bin attachment fitting at Station 680, which could result in the overhead stowage bin falling onto the passenger seats below and injuring passengers or impeding the evacuation of passengers in an emergency. This action is intended to address the identified unsafe condition.
