Airworthiness Directives; Rolls-Royce plc Turbofan Engines

We are adopting a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) Trent 1000-A2, Trent 1000-AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 model turbofan engines. This AD was prompted by reports of intermediate-pressure compressor (IPC) rotor seal failures. This AD requires initial and repetitive on-wing borescope inspections (BSIs) of affected IPC rotor seals and removing any cracked parts from service. We are issuing this AD to address the unsafe condition on these products.
