Airworthiness Directives; Boeing Model 757-200 and -200PF Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 757-200 and -200PF series airplanes, that requires repetitive detailed visual inspections to detect loose fuse pins in the outboard beam attachment and forward trunnion support on the main landing gear (MLG) and to detect corrosion on the structure adjacent to the fuse pin; and corrective actions, if necessary. This amendment also requires eventual replacement of the fuse pins with new corrosion resistant steel (CRES) fuse pins, which constitutes terminating action for the repetitive inspections. This amendment is prompted by a report of damaged fuse pins caused by corrosion. The actions specified by this AD are intended to prevent corroded fuse pins, which could result in the MLG separating from the wing, and consequent damage to the airplane and possible rupture of the wing fuel tank.
