What the agency says
The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 1000-A, Trent 1000-A2, Trent 1000-AE, Trent 1000-AE2, Trent 1000-C, Trent 1000- C2, Trent 1000-CE, Trent 1000-CE2, Trent 1000-D, Trent 1000-D2, Trent 1000-E, Trent 1000-E2, Trent 1000-G, Trent 1000-G2, Trent 1000-H, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 engines. This proposed AD was prompted by reports of wear in the combining spill valve (CSV) assembly of certain hydro-mechanical units (HMUs). This proposed AD would require removing certain HMUs from service and replacing with a serviceable part. This proposed AD would also prohibit installation of certain HMUs unless the HMU is a serviceable part or the CSV assembly has been replaced, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
