Airworthiness Directives; General Electric Company Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF34-1A, CF34-3A, CF34-3A1, CF34-3A2, CF34-3B, and CF34-3B1 model turbofan engines. This proposed AD was prompted by an in-flight failure of a fan blade that led to an in-flight shutdown. This proposed AD would require removal and replacement of the affected fan blades. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Various Transport Airplanes
The FAA is adopting a new airworthiness directive (AD) for various transport airplanes. This AD was prompted by reports of smoke and fumes in the flight deck. This AD requires modification of certain universal serial bus (USB) receptacles located in the flight deck. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
The FAA is superseding airworthiness directive (AD) 2018-15-01 for certain Rolls-Royce plc (RR) Trent 1000-A, Trent 1000-C, Trent 1000-D, Trent 1000-E, Trent 1000-G, Trent 1000-H, 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 model turbofan engines. AD 2018-15-01 required certain engines susceptible to intermediate- pressure turbine (IPT) blade failure not be installed on an airplane together with other engines with IPT blades of the same cyclic life. This AD requires removal of the IPT blade set at lower cyclic life limits and replacing it with a blade set eligible for installation. This AD also expands the applicability to include additional Trent 1000 turbofan engine models. This AD was prompted by the determination that certain IPT blades are susceptible to shank corrosion which leads to cracking and possible blade separation. The FAA is issuing this AD to address the unsafe condition on these products.
