EASA puts limit on batch of Trent 1000 compressor cases

Operators of some Rolls-Royce Trent 1000-powered Boeing 787s are being cautioned over time limits for low-pressure compressor front cases. Engineering analysis has found that 38 of such cases have "non-optimal material properties", says EASA. It states that this could "inhibit" the ability of the engine to contain high-energy debris in the event of a fan-blade failure, resulting in release of debris. Rolls-Royce has developed an updated life management for the parts and identified the engines which have those components installed in a service bulletin. EASA is set to require removal of the affected engines from service in order to replace the front cases of the low-pressure compressor, in accordance with the ultimate dates listed in the bulletin. <br/>
