Airworthiness Directives; Boeing Model 757-200, -200PF, and -200CB Series Airplanes Equipped With Pratt & Whitney or Rolls-Royce Engines

الملخص

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200, -200PF, and -200CB series airplanes. This AD requires inspecting to determine the part number of the upper link forward fuse pins of the engine struts and replacing the fuse pins as necessary. This AD is prompted by a report indicating that, due to an incorrect listing in the illustrated parts catalog, persons performing maintenance on the engine strut(s) could have installed an incorrect upper link forward fuse pin. We are issuing this AD to prevent a ruptured wing box, due to the engine not separating safely during certain emergency landing conditions, which could lead to a fuel spill and consequent fire.
