Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd. & Co KG (RRD) Trent 1000-AE3, Trent 1000- CE3, Trent 1000-D3, Trent 1000-G3, Trent 1000-H3, Trent 1000-J3, Trent 1000-K3, Trent 1000-L3, Trent 1000-M3, Trent 1000-N3, Trent 1000-P3, Trent 1000-Q3, and Trent 1000-R3 model turbofan engines. This AD requires initial and repetitive borescope inspections (BSI) of the high-pressure turbine (HPT) blades. This AD also requires replacement of HPT blades with parts eligible for installation when the HPT blades fail inspection or reach the new life limit. This AD was prompted by the manufacturer identifying that the HPT blades may fail prematurely. The FAA is issuing this AD to address the unsafe condition on these products.
Establishment of Area Navigation (RNAV) Routes; Northeastern United States
This action establishes two new low altitude RNAV routes, designated T-356, and T-358, in the northeastern United States. The new routes enhance the efficiency of the National Airspace System (NAS) by expanding the availability of RNAV routing and supporting the transition of the NAS from ground-based to satellite-based navigation. Originally, this docket action also proposed to establish routes T-303, T-307, T-320, T-324, and T-335. However, subsequent to the NPRM, the FAA determined that those routes require further development, so they will be addressed in separate docket actions at a later date.
Amendment of VOR Federal Airway V-18 in the Vicinity of Talladega, AL
This action modifies VHF Omnidirectional Range (VOR) Federal airway V-18, in the vicinity of Talladega, AL. This action is necessary due to the planned decommissioning of the Talladega, AL, VOR/DME navigation aid which provides navigation guidance for segments of the route. Additionally, this action removes the compulsory reporting point requirement for the HEFIN, AL, navigation fix.
