Abstract
We are adopting a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211 Trent 553-61, 553A2-61, 556-61, 556A2-61, 556B-61, 556B2-61, 560-61, and 560A2-61 turbofan engines. We are issuing this AD to address, through an update to the electronic engine control (EEC) software, multiple risks of uncontained engine failure and damage to the airplane.
