Abstract

The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 1000-A, Trent 1000-AE, Trent 1000-C, Trent 1000-CE, Trent 1000-D, Trent 1000-E, Trent 1000-G, Trent 1000-H, 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 engines. This AD was prompted by an investigation which revealed that certain low- pressure compressor (LPC) fan blades are at risk of cracking due to incorrect dressing. This AD requires inspecting the LPC fan blades for evidence of incorrect dressing, and replacement if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
