Airworthiness Directive · Amendment 39-10205 · Boeing Model 777-200 Series Airplanes
Boeing Model 777-200 Series Airplanes
Model 777-200 series airplanes, as listed in Boeing Alert Service Bulletin 777-23A0027, dated February 13, 1997; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777-200 series airplanes, that requires replacement of certain overhead electronics units (OEU) of the passenger address and entertainment communication systems with modified OEU's. This amendment is prompted by reports of smoke coming from the overhead panels near the passenger reading lights, which was caused by overheating of the transformers located in the OEU's. The actions specified by this AD are intended to prevent overheating of the transformers, which potentially could cause a fire in the transformer assembly and/or electronic components located in the OEU and could cause smoke to enter the passenger cabin.
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.
