Abstract
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.
