The FAA proposes to supersede Airworthiness Directive (AD) 2015-02-14, which applies to all Airbus SAS Model A318 series airplanes; A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; A320-211, -212, -214, -231, -232, and -233 airplanes; and A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2015-02-14 requires repetitive inspections for cracking, damage, correct installation, and correct adjustment of the main landing gear (MLG) door hinge and actuator fittings on the keel beam, corrective actions if necessary, and revision of the existing maintenance or inspection program, as applicable. Since the FAA issued AD 2015-02-14, a new design of the MLG door keel beam hinge and actuator fitting was developed. This proposed AD would continue to require the actions specified in AD 2015-02-14, add an optional terminating action, and revise the applicability, 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.

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.

This action proposes to amend Very High Frequency Omnidirectional Range (VOR) Federal Airways V-161, V-163, and V-568; and to establish United States Area Navigation (RNAV) Route T-545. The FAA is proposing this action due to the planned decommissioning of the VOR portion of the Three Rivers, TX (THX), VOR/Tactical Air Navigation (VORTAC) navigational aid (NAVAID). The Three Rivers VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.

These special conditions are issued for the Airbus Model A321 neo ACF and A321 neo XLR airplanes. These airplanes have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature incorporates oblique (side-facing) passenger seats which may include a 3-point restraint system with pretensioner. These oblique seats may be installed at an angle of 18 to 45 degrees to the aircraft centerline and have surrounding furniture that introduces occupant and loading concerns. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

Each sponsor has previously identified to the FAA such projects through the Airports Capital Improvement Plan (ACIP) process. This action also announces April 28, 2025, as the deadline for an airport sponsor to submit a final grant application, based on bids, for grants that will be funded with FY 2025 entitlement funds only.

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations for certain brake accumulators are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD also requires determining the accumulated landings on the affected brake accumulators. The FAA is issuing this AD to address the unsafe condition on these products.

This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures 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 for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

This action proposes to modify the Class E airspace extending upward from 700 feet above the surface and remove the Class E airspace extending upward from 1,200 feet above the surface at Cheyenne Regional/Jerry Olson Field, Cheyenne, WY. Additionally, this action proposes administrative amendments to update the airport's legal descriptions for its Class D airspace and Class E airspace designated as a surface area. These actions would support the safety and management of visual flight rules (VFR) and instrument flight rules (IFR) operations at the airport.

The FAA proposes to supersede Airworthiness Directive (AD) 2021-09-14, which applies to certain Airbus Helicopters (Airbus) Model SA330J helicopters. AD 2021-09-14 requires repetitively inspecting for a gap between the main gearbox (MGB) oil cooling fan assembly (fan) rotor blade and the upper section of the guide vane bearing housing, installing improved MGB fan rotor shaft bearings, and repetitively inspecting the improved MGB fan rotor shaft bearings. Since the FAA issued AD 2021-09-14, Airbus has developed modifications to the components of the MGB fan bearing assembly and issued new material regarding these modifications. This proposed AD would retain the actions required by AD 2021-09-14 and would also require installing the improved MGB fan rotor bearing assembly, which would constitute terminating action for the repetitive inspections. 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.
