Boeing Model 777-200 Series Airplanes
Model 777-200 series airplanes, as listed in Boeing Service Bulletin 777-27-0057, dated August 22, 2002; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777-200 series airplanes, that requires a one-time general visual inspection of wire bundles routed aft of electrical disconnect panel AC2162 to determine their installation and separation, and corrective actions, if necessary. This action is necessary to prevent damage to the stabilizer cutout circuit wires in the bundles due to contact between the bundles and the adjacent galley water drain tube and hydraulic tubes, which, if followed by an active fault in the stabilizer command circuit, could result in undesired stabilizer motion that cannot be stopped, and could lead to loss of pitch control and loss of control of the airplane. This action is intended to address the identified unsafe condition.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
