✈️New Airworthiness Directives for General Electric Jet Engines Proposed
The FAA is revising a notice of proposed rulemaking (NPRM) that applied to certain General Electric Company (GE) Model CF34- 10E2A1, CF34-10E6, CF34-10E6A1, CF34-10E7, and CF34-10E7-B engines having certain high-pressure turbine (HPT) front rotating air seals installed. This action revises the NPRM by adding Model CF34-10E5 and CF34-10E5A1 engines to the applicability. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, the agency is requesting comments on this SNPRM.

This action proposes to modify the Class E airspace extending upward from 700 feet above the surface of the earth to provide additional instrument flight procedure containment at Yellowstone Regional Airport, Cody, WY. Additionally, this action proposes administrative amendments to update the airport's Class E airspace legal description. These actions would support the safety and management of instrument flight rules (IFR) operations at the airport.
Learn More✈️Proposed Amendment to Class E Airspace in Iron Mountain, MI
This action proposes to amend the Class E airspace at Iron Mountain/Kingsford, MI. The FAA is proposing this action as the result of an airspace review conducted due to the decommissioning of the Iron Mountain very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. This action will bring the airspace into compliance with FAA orders and support instrument flight rule (IFR) procedures and operations.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC135T3, EC635T2+, MBB- BK 117 C-2, MBB-BK 117 D-2, and MBB-BK 117 D-3 helicopters. This proposed AD was prompted by a review of design data and the determination for recalculation of accumulated hoist boom cycles (cycles) and repetitive inspections. This proposed AD would require determining the total cycles of certain hoist boom assemblies, inspecting those hoist boom assemblies, and depending on the results, taking corrective action. This proposed AD would also prohibit installing those hoist boom assemblies unless certain requirements are met. These actions are 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.

This action proposes to amend the Class E airspace at Nappanee, IN. The FAA is proposing this action as the result of an airspace review conducted due to the decommissioning of the Goshen very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates of the Nappanee Municipal Airport, Nappanee, IN, 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.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC635T2+, and EC135T3 helicopters. This proposed AD was prompted by reports of ruptured and deformed flexible couplings. This proposed AD would require inspecting the axial displacement of the tail rotor driveshaft and, depending on the results, taking corrective actions including inspecting the flexible couplings. This proposed AD would also prohibit installing a tail rotor drive shaft unless certain procedures are followed. These actions are 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.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters. This proposed AD was prompted by reports of false engine fire warnings. This proposed AD would require replacing affected engine fire detectors and prohibit installing an affected engine fire detector or an engine that contains an affected engine fire detector, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

The Environmental Protection Agency (EPA) is proposing to modify nitrogen oxide (NO<INF>X</INF>) emission limits for the indurating furnace at United States Steel's (U.S. Steel's) Keetac taconite facility in Keewatin, Minnesota (Keetac), to satisfy the requirement for best available retrofit technology (BART) at taconite facilities. EPA is proposing this action pursuant to sections 110 and 169A of the Clean Air Act (CAA).
Learn More✈️Updates on Standard Instrument Approach Procedures by FAA
This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
