Rolls-Royce plc Models RB211 Trent 768-60, Trent 772-60, and Trent 772B-60 Turbofan Engines
This AD applies to Rolls-Royce plc (RR) Model RB211 Trent 768-60, Trent 772-60, and Trent 772B-60 turbofan engines with Engine Electronic Controllers (EECs) listed by P/N in the following Table 1:
| EEC2000.06.BB.1 |
| EEC2000-06-BE-1 |
| EEC2000-06-BG-1 |
| EEC2000-06-BH-1 |

These engines are installed on, but not limited to, Airbus A330 series airplanes.
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce plc (RR) models RB211 Trent 768-60, Trent 772-60, and Trent 772B-60 turbofan engines. This AD requires removal of certain Engine Electronic Controller (EEC) part numbers from service. This AD results from nine reports of loss of engine parameters displayed in the airplane cockpit, with the simultaneous loss of capability to change thrust of the affected engine. We are issuing this AD to prevent loss of airplane control after an aborted takeoff due to asymmetric thrust.
You are responsible for having the actions required by this AD performed before July 31, 2006, unless the actions have already been done.
Remove from service the EECs with part numbers listed in Table 1 of this AD.
(g) Information on the EEC software changes can be found in Rolls-Royce Alert Service Bulletin No. RB.211-73-AE324, Revision 2, dated November 1, 2004.
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.
