The FAA proposes to supersede Airworthiness Directive (AD) 2024-23-06, which applies to certain MD Helicopters, LLC (MDHI) Model 369, 369A, 369D, 369E, 369F, 369FF, 369H, 369HE, 369HM, 369HS, 500N, and 600N helicopters. AD 2024-23-06 requires repetitively inspecting the torque tube assembly and roller bearings, and depending on the results, replacing parts or accomplishing additional inspections. Since the FAA issued AD 2024-23-06, it has been determined that additional torque tube assemblies are affected by this unsafe condition. This proposed AD would continue to require the actions of AD 2024-23-06 and would expand the applicability. 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 LAVIA ARGENTINA S.A. (LAVIASA) Model PA-25, PA-25-235, and PA- 25-260 airplanes. This proposed AD was prompted by reports of corrosion in the front and rear wing spars and cracks in the front wing spar. This proposed AD would require inspecting the front and rear wing spars for corrosion and crack(s); inspecting the upper/lower spar flange of the front wing spar for any crack(s); repairing or replacing front and rear wing spars if crack(s) or corrosion are found, as applicable. The FAA is proposing this AD to address the unsafe condition on these products.
The Department is withdrawing the ANPRM on Airline Passenger Rights issued on December 11, 2024. The ANPRM sought public comment on a potential regulatory action that would require airlines to provide passengers affected by significant flight disruptions with a variety of costly measures. The withdrawal of this ANPRM is consistent with Executive Order (E.O.) 14192, "Unleashing Prosperity Through Deregulation," which directs Federal agencies to reduce regulatory burdens, and E.O. 14219, "Ensuring Lawful Governance and Implementation of the President's `Department of Government Efficiency' Deregulatory Agenda," which directs Federal agencies to identify and to repeal or to modify regulations that are unlawful or unauthorized.
The FAA is superseding Airworthiness Directive (AD) 2023-05- 13, which applied to all Airbus SAS Model A300 B4-600, B4-600R, and F4- 600R series airplanes; and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). AD 2023-05-13 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-05-13, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require the actions in AD 2023-05-13 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A330-200, -200 Freighter, -300, -800, and -900 series airplanes. This proposed AD was prompted by the identification of an incorrect shot peening application implemented in production. This proposed AD would require repetitive special detailed inspections (SDIs) of affected central windshield frames and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
This action corrects a final rule published by the FAA in the Federal Register on September 3, 2025, amending Very High Frequency Omnidirectional Range (VOR) Federal Airways V-55, V-100, and V-277 due to the planned decommissioning of the VOR portion of the Keeler (ELX), MI, VOR/Distance Measuring Equipment (VOR/DME) in support of the FAA's VOR Minimum Operational Network (MON) program. Specifically, this action administratively corrects errors within the description of V-55 in the final rule as published on September 3, 2025.
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-8F series airplanes. This proposed AD was prompted by reports of cracking in stringers and splice fittings located at stringer splices at multiple body stations. This proposed AD would require an inspection of each free flange of the stringers at the stringer splice for radius fillers at certain fastener locations, an inspection for cracking of the stringers and stringer splice fittings at certain stringer splice locations, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
This action is an administrative change to rename restricted areas R-6302A, R-6302B, R-6302C, R-6302D, and R-6302E; Fort Cavazos, TX, and to update the using agency description to reflect the change.

Since the FAA issued AD 2024-19-13, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require certain actions in AD 2024- 19-13 and would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This proposed AD would also add Model A319- 173N and Model A321-253NY airplanes to the applicability. The FAA is proposing 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.
