Airworthiness Directives; Airbus Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC225LP helicopters. This AD was prompted by a report of water in the oil of a main gearbox (MGB). This AD requires replacing certain main rotor (M/R) mast upper stops assembly screws. This AD also requires inspecting certain M/R mast cover plates and accomplishing MGB oil analyses and, depending on the results, taking corrective action. This AD prohibits installing certain M/R mast upper stops assembly screws, M/R masts with an affected M/R mast upper stops assembly screw installed, and used M/R mast cover plates on any helicopter. Lastly, this AD prohibits installing affected M/R masts unless the inspections are done. These actions are 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 Class E Airspace; Claremont, NH
This action amends Class E airspace extending upward from 700 feet above the surface for Claremont Municipal Airport, Claremont, NH, as the Claremont Non-directional Beacon (NDB) has been decommissioned and associated instrument approaches canceled. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
Amendment of United States Area Navigation (RNAV) Route Q-83; Eastern United States
This action amends United States Area Navigation (RNAV) Route Q-83 in the eastern United States. This action supports the Northeast Corridor Atlantic Coast Routes (NEC ACR) Optimization Project to improve the efficiency of the National Airspace System (NAS).
Amendment of Class D and Class E Airspace and Revocation of Class E Airspace; Youngstown/Warren, OH
This action proposes to amend the Class D and Class E airspace and revoke Class E airspace at Youngstown/Warren, OH. The FAA is proposing this action as the result of an airspace review conducted due to the decommissioning of the Youngstown very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. The name and geographic coordinates of the airport would also be updated to coincide with the FAA's aeronautical database. This action will bring the airspace into compliance with FAA orders and support instrument flight rule (IFR) procedures and operations.
Amendment of Class E Airspace; Ottumwa, IA
This action proposes to amend the Class E airspace at Ottumwa, IA. The FAA is proposing this action as the result of an airspace review conducted due to the decommissioning of the Ottumwa very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. This action would also update the name and geographic coordinates of the airport to coincide with the FAA's aeronautical database. This action will bring the airspace into compliance with FAA orders and support instrument flight rule (IFR) procedures and operations.
Establishment of Class E Airspace; Washburn, ND
This action proposes to establish Class E airspace at Washburn, ND. The FAA is proposing this action due to the development of new public instrument procedures at Washburn Municipal Airport, Washburn, ND, and to support instrument flight rule (IFR) operations.
Extension of the Prohibition Against Certain Flights in the Tehran Flight Information Region (FIR) (OIIX)
This action extends the prohibition against certain flight operations in the Tehran Flight Information Region (FIR) (OIIX) by all: U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when the operator of such aircraft is a foreign air carrier, for an additional three years, from October 31, 2024, to October 31, 2027. The FAA finds this action necessary to address significant unacceptable safety-of-flight risks to U.S. civil aviation operations that continue in the Tehran FIR (OIIX) during periods of heightened regional tensions and increased military activities. The FAA also republishes the approval process and exemption information for this Special Federal Aviation Regulation (SFAR), consistent with other recently published flight prohibition SFARs.
Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2022-19-09, which applies to all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2022-19-09 requires repetitive inspections of the left and right main landing gear (MLG) lower spindle pins to detect corrosion, and applicable repair or replacement. Since the FAA issued AD 2022-19-09, the tracking of flight cycles for inspections was changed from the usage of the MLG to the usage of MLG lower spindle assemblies and a replacement was developed, which would terminate the inspections. This proposed AD continues to require certain actions in AD 2022-19-09, would change the tracking of flight cycles for inspections from the usage of the MLG to the usage of MLG lower spindle assemblies, and would require replacement of affected MLG lower spindle assemblies, as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR). This proposed AD also would remove airplanes from the applicability. This proposed AD would also prohibit the installation of affected parts under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.
