Airworthiness Directives; De Havilland Aircraft of Canada Limited (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-401 and - 402 airplanes. This AD was prompted by a report of an in-flight event where isolation valve caution messages were received. This AD requires inspecting the fuse/shuttle valve serial numbers, and replacing certain fuse/shuttle valves, as specified in a Transport Canada AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
The FAA is superseding Airworthiness Directive (AD) 2023-05- 08, which applied to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2023-05-08 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2023-05-08 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model Airbus A350-941 and -1041 airplanes. This AD was prompted by a determination that the lower attachment studs on the aft galley complex may be installed incorrectly due to a missing instruction in the maintenance procedure task. This AD requires a one- time inspection of the lower attachment studs on the aft galley complex, and depending on findings, accomplishment of applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Amendment of Domestic Very High Frequency Omnidirectional Range (VOR) Federal Airways V-1, V-29, V-38, V-139, and V-286; Eastern United States
This action proposes to amend domestic Very High Frequency Omnidirectional Range (VOR) Federal Airways V-1, V-29, V-38, V-139, and V-286 in the eastern United States. The FAA is taking this action due to the planned decommissioning of the Salisbury, MD (SBY) VOR/Tactical Air Navigation (VORTAC) and the Snow Hill, MD (SWL), VORTAC. This action is in support of the FAA's VOR Minimum Operational Network (MON) Program.
Amendment of Domestic Very High Frequency Omnidirectional Range (VOR) Federal Airways V-7, V-35, V-157, V-159, and V-198; Eastern United States
This action proposes to amend domestic Very High Frequency Omnidirectional Range (VOR) Federal Airways V-7, V-35, V-157, V-159, and V-198 in the eastern United States. The FAA is taking this action due to the planned decommissioning of the Cross City, FL (CTY), VOR/ Tactical Air Navigation (VORTAC) and the Taylor, FL (TAY), VORTAC. This action is in support of the FAA's VOR Minimum Operational Network (MON) Program.
Airworthiness Directives; The Boeing Company Airplanes
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by a report that during manufacture of drag brace lower lock link assemblies for the main landing gear (MLG), a certain required inspection was not performed. This AD requires doing a check of maintenance records or an inspection to determine if certain drag brace lower lock link assemblies are installed, and applicable on-condition actions. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Engines.
The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) Model CT7-5A2, CT7-5A3, CT7- 7A, CT7-7A1, CT7-9B, CT7-9B1, CT7-9B2, CT7-9C, CT7-9C3, CT7-9D, and CT7-9D2 engines. This proposed AD was prompted by the manufacturer's determination that certain GE Model CT7 fleets have affected cooling plates installed that do not meet lifing guidelines. This proposed AD would require replacement of the stage 1 turbine forward cooling plate and the stage 2 turbine aft cooling plate. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
The FAA proposes to supersede Airworthiness Directive (AD) 2022-24-06, which applies to certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model BR700-710A1-10, BR700-710A2-20, and BR700-710C4-11 engines. AD 2022-24-06 requires initial and repetitive visual inspections of certain low-pressure compressor (LPC) rotor (fan) disks and replacement of any LPC rotor (fan) disk with cracks detected. AD 2022-24-06 also allows for modification of the engine in accordance with RRD service information as a terminating action to these inspections. Since the FAA issued AD 2022-24-06, the manufacturer published updated service information and revised the engine maintenance manual (EMM) to provide instructions for an improved ultrasonic inspection method, which prompted this AD. This proposed AD would require initial and repetitive visual inspections of certain LPC rotor (fan) disks and replacement of any LPC rotor (fan) disk with cracks detected and would allow modification of the engine as a terminating action to the inspections, 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.
Airworthiness Directives; Pratt & Whitney Canada Corp. Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain Pratt & Whitney Canada Corp. (P&WC) Model PW535E and PW535E1 engines. This proposed AD was prompted by a manufacturer design review that indicated certain flange bolts securing the gas generator case and turbine support case are susceptible to cracking at their current low-cycle fatigue (LCF) life. This proposed AD would require repetitive borescope inspections (BSI) of the gas generator case to turbine support case retaining bolts for evidence of bolt cracks, bolt fracture, missing bolts, or loose bolts and replacement, if necessary, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
