Airworthiness Directive · Amendment 39-13521 · Boeing Model 777 Series Airplanes
Boeing Model 777 Series Airplanes
Model 777 series airplanes, as listed in Boeing Service Bulletin 777-25-0191, dated September 13, 2001; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777 series airplanes, that requires replacement of the cargo control joysticks with new joysticks that include a moisture seal and ventilated cover. This action is necessary to prevent water from being trapped inside the joystick covers, which could result in uncommanded movements of the power drive unit during ground handling of cargo and consequent possible injury to ground personnel. 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.
