Airworthiness Directives; Boeing Model 767-200 and -300 Series Airplanes

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) T95-20-51 that was sent previously to all known U.S. owners and operators of Boeing Model 767- 200 and -300 series airplanes by individual telegrams. This AD requires inspections of the lower half of the aft trunnion of the main landing gear (MLG) to detect damage, cracking, missing pieces, or corrosion; and correction of discrepancies. This amendment is prompted by a report indicating that the MLG collapsed on an airplane due to fracture of the aft trunnion outer cylinder that was caused by stress corrosion cracking. The actions specified by this AD are intended to prevent the collapse of the MLG due to the problems associated with stress corrosion cracking in the aft trunnion assembly; collapse of the MLG could lead to loss of control of the airplane during landing, taxiing, and takeoff.
