Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 777-200 and -300 series airplanes. This action requires a one-time torque check (inspection) of the bolts that attach the pivot fittings to the horizontal stabilizer through the upper and lower titanium straps, to determine if the bolts are adequately torqued, and follow-on actions. This action is necessary to prevent failure of the pivot fittings, which could result in loss of control of the horizontal stabilizer and consequent loss of control of the airplane. This action is intended to address the identified unsafe condition.
