Airworthiness Directives; Boeing Model 767 Series Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 767 series airplanes. This action requires operators to perform visual inspections of the outer cylinder aft trunnion on the main landing gear to determine if the fillet seal is cracked or missing. This action also requires operators to inspect for evidence of corrosion in this location. Finally, this action prescribes the procedures that operators must follow if corrosion is found. This amendment is prompted by several reports of fractures of the outer cylinder aft trunnion due to stress corrosion cracking. The actions specified in this AD are intended to ensure that corrosion is not present in this location, thereby preventing future failures due to stress corrosion cracking.
