The FAA is adopting a new airworthiness directive (AD) for certain Rolls-Royce (RR) plc RB211 Trent 556-61 turbofan engines. This AD requires a gauge inspection of the space between the high pressure (HP) fuel tubes adaptor face and seals, and a gauge inspection of the space between the fuel flow transmitter and seals, for evidence of permanent distortion of the face of the fuel tube connecting flanges, and replacement of parts if necessary. This AD is prompted by a report of fuel leaking from the engine fan cowl during an aircraft taxi. We are issuing this AD to prevent in-flight fuel leaks, which could result in an engine fire.
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.
