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-C2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 turbofan engines. This AD requires initial and repetitive on-wing inspections of affected intermediate pressure compressor (IPC) rotor seals. This AD was prompted by a failure of the IPC rotor seal. We are issuing this AD to correct the unsafe condition on these products.
