The FAA proposes to supersede Airworthiness Directive (AD) 2024-24-02, which applies to all Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2F engines. AD 2024-24-02 requires removal of the affected fuel control unit (FCU) from service and replacement with a serviceable part. Since the FAA issued AD 2024-24-02, it was determined that certain serial numbers of the affected FCUs are not subject to the unsafe condition. This proposed AD would continue to require removal of the affected FCU from service and replacement with a serviceable part. This proposed AD would also reduce the number of affected FCUs. The FAA is proposing this AD to address the unsafe condition on these products.
This action proposes to amend the Class E airspace at Covington, KY. The FAA is proposing this action as the result of airspace reviews conducted due to the decommissioning of the Cincinnati very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. This action would bring the airspace into compliance with FAA orders and support instrument flight rule (IFR) procedures and operations.
The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model GVI airplanes. This AD was prompted by a determination that new and more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new and more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model GVII-G500 and GVII-G600 airplanes. This AD was prompted by a determination that new and more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new and more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is superseding Airworthiness Directive (AD) 2025-23- 52, which applied to all Airbus Helicopters Model EC130B4 and EC130T2 helicopters. AD 2025-23-52, required replacing the center shaft assembly with a serviceable center shaft assembly (either a shaft with another part number (P/N) or the same P/N with lower hours time-in- service (TIS)) and prohibited installing a center shaft assembly that is not a serviceable center shaft assembly on any helicopter. Since the FAA issued AD 2025-23-52, it was determined that for certain center shaft assemblies a repetitive inspection is adequate instead of replacement. This AD requires repetitively inspecting the center shaft assembly for cracks and replacing the center shaft assembly if it fails the inspection or exceeds a certain TIS. This AD also prohibits installing a center shaft assembly that is not a serviceable center shaft assembly on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-9 and 787-10 airplanes. This AD was prompted by reports of multiple supplier notices of escapement (NOEs) indicating that ram air turbine (RAT) forward fittings were possibly manufactured with an incorrect titanium alloy material. This AD requires a high frequency eddy current (HFEC) or handheld X-ray fluorescence (XRF) spectrometer inspection of the RAT forward fitting to determine the titanium alloy material and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757-200 and -300 series airplanes. This AD was prompted by cracking found during an inspection on an airplane equipped with Aviation Partners Boeing (APB) scimitar blended winglets. This AD requires performing a general visual inspection (GVI) or maintenance records check of certain stringers for an approved freeze plug repair, performing a high frequency eddy current (HFEC) inspection of the same area for any crack common to a certain stringer and a reinforcement strap, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-9 and 787-10 airplanes. This AD was prompted by reports of multiple supplier notices of escapement (NOEs) indicating that multiple cargo barrier fitting links were possibly manufactured with an incorrect titanium alloy material. This AD requires a high frequency eddy current (HFEC) or handheld X-ray fluorescence (XRF) spectrometer inspection of the cargo barrier fitting link to determine the titanium alloy material and applicable on- condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD 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 is correcting a notice of proposed rulemaking (NPRM) that was published in the Federal Register. The NPRM proposed to issue an airworthiness directive (AD) that would apply to certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. As published, the docket number referenced throughout the NPRM is incorrect. This document corrects that error. In all other respects, the original document remains the same; however, for clarity, the FAA is publishing the entire proposed rule in the Federal Register.
This final rule amends MARAD's regulations governing Seamen's Service Awards. The amendment changes the name "Gulf of Mexico" to "Gulf of America" consistent with Executive Order (E.O.) 14172, Restoring Names that Honor American Greatness. The amendment also provides factual clerical changes, such as updating citations to authority and physical office names and addresses.
This document partially grants a petition for reconsideration of the October 30, 2024 final rule that established Federal Motor Vehicle Safety Standard (FMVSS) No. 217a, "Anti-ejection glazing for bus portals; Mandatory applicability beginning October 30, 2027." The standard intends to drive installation of advanced glazing in over-the- road buses (motorcoaches) and other large buses to reduce occupant ejections. This final rule revises the minimum size requirement for applicable portals, adds a figure to illustrate a daylight opening periphery, and clarifies the target location for edge impact tests. This document denies all other portions of the petition for reconsideration, including revising the definition of "daylight opening."
This action amends Jet Route J-146 and establishes United States Area Navigation (RNAV) Route Q-186 segments within U.S. airspace. The FAA is taking this action due to the planned decommissioning of the Very High Frequency Omnidirectional Range (VOR) portion of the Chardon, OH (CXR), VOR/Distance Measuring Equipment (VOR/DME) navigational aid (NAVAID). The Chardon VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.
This action corrects a final rule that FAA published in the Federal Register on December 8, 2025. The final rule established Class E airspace extending upward from 700 feet above the surface for Zuni, NM. This action corrects an error in the legal description.
This document informs the public that FAA has determined not to pursue the previously published NPRM, which proposed to require that upper stages of commercial launch vehicles and other components resulting from launch or reentry be removed from orbit within 25 years after launch, either through atmospheric disposal or maneuver to an acceptable disposal orbit. FAA is withdrawing this action to further consider comments received.
PHMSA is updating its regulations to allow operators to apply modern risk management principles in addressing the safety of gas pipelines affected by class location changes. Relying on an approach originally developed in the 1950s, PHMSA's regulations use class locations to provide an additional margin of safety in the design, construction, testing, operation, and maintenance of gas pipelines based on population density. When the class location of a pipeline changes due to an increase in population density, an operator may need to take certain actions to confirm or to revise the maximum allowable operating pressure of a segment. Because the methods traditionally used for that purpose do not account for modern risk management principles, PHMSA has granted special permits for more than two decades allowing operators to use an integrity-management-based alternative. This final rule adopts that `IM alternative' by regulation to provide operators with an additional method for confirming or restoring the maximum allowable operating pressure of certain eligible segments that experience class location changes.
PHMSA is adopting several amendments to the Hazardous Materials Regulations to reduce unnecessary regulatory burdens associated with the safe transportation of hazardous materials, including energy products. These amendments will reduce costs for hazardous materials transporters and eliminate unnecessary regulatory burdens on fuel transportation while maintaining or increasing the level of safety provided in the Hazardous Materials Regulations.
NHTSA is announcing a 15-day extension of the comment period for the proposed rule entitled The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule III for Model Years 2022 to 2031 Passenger Cars and Light Trucks, published in the December 5, 2025 issue of the Federal Register. NHTSA is also extending the comment period for the Draft Supplemental Environmental Impact Statement (Draft SEIS) that accompanies the proposed rule. The comment period was to end on January 20, 2026 (45 days after publication of the proposed rule in the Federal Register). This document extends the comment period to February 4 to allow the public additional time to comment on the proposed rule. NHTSA is denying requests for additional public hearings based on the number of testifiers that signed up to testify for NHTSA's virtual public hearing, which was announced via Federal Register notice on December 12, 2025 and held on January 7, 2026.
This action proposes to amend the Class D airspace and establish Class E airspace at Fort Worth, TX. The name and geographic coordinates of Fort Worth Meacham International Airport, Fort Worth, TX, and the name of Fort Worth NAS \1\ JRB (Carswell Field), Fort Worth, TX, would also be updated to coincide with the FAA's aeronautical database. The FAA is proposing these actions to accommodate a U.S. Navy request to change the Fort Worth NAS JRB (Carswell Field) Class D airspace from full-time to part-time and establish part-time Class E surface airspace; the associated airspace reviews conducted to accommodate this request; and a biennial airspace review of the Perot Field/Fort Worth Alliance Airport, Fort Worth, TX. These actions will bring the airspace into compliance with FAA orders and support instrument flight rule (IFR) procedures and operations. ---------------------------------------------------------------------------
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.
The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-700, -700C, -800, -900, and -900ER series airplanes. This proposed AD was prompted by reports of cracks in the outward lower wing skin at the outboard end of a certain stringer. This proposed AD would require an inspection of the outboard lower wing skin on the left and right wing for any repair, repetitive inspections for cracking and applicable on-condition actions. 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 certain Airbus SAS Model A319-111, -112, -113, -114, -115, -131, - 132, and -133 airplanes; Model A320 series airplanes; and Model A321- 211, -212, -213, -231,-232, -251N, -251NX, -252N, -252NX, -253N, - 253NX, -271N, -271NX, -272N, and -272NX airplanes. This proposed AD was prompted by a review of the cold working process on the assembly line that detected a deviation to the manufacturing process. This proposed AD would require repetitive inspections for the nominal design condition of the fastener holes in the pressure deck membrane to center wing box attachment and, as applicable, an inspection for cracking at the affected area and corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
This action proposes to amend the Class E airspace extending upward from 700 feet above the surface at Morganton, NC, by expanding the airspace to encompass Carolinas Healthcare System Blue Ridge, Morganton, NC. It would also update the name of the former Morganton- Lenoir Airport to Foothills Regional Airport, Morganton, NC, as the airport has changed its name. Finally, it would remove the Grace Hospital reference along with the point in space coordinates, as Grace Hospital no longer exists. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 A-1, MBB-BK 117 A-3, MBB-BK 117 A-4, MBB-BK 117 B-1, MBB-BK 117 B-2, and MBB-BK 117 C-1 helicopters. This proposed AD was prompted by a report of a main rotor head (MRH) having the same part number (P/N) and serial number (S/N) as another MRH due to incorrect modification instructions where the modified part serial number was not re-identified and the MRH can be operated with the wrong associated log card if accidently interchanged. This proposed AD would require performing a one-time consistency check of the P/N and S/N of the MRH, performing corrective actions if applicable, determining if the MRH has been modified, and re-identifying the modified MRH. The proposed AD would also allow replacing the MRH as an optional action and would prohibit the installation of an affected MRH on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
This action proposes to amend the Class D airspace and establish Class E airspace at Chandler and Phoenix, AZ. The name and geographic coordinates of the Mesa Gateway Airport, Phoenix, AZ, would also be updated to coincide with the FAA's aeronautical database. The FAA is proposing this action due to biennial airspace reviews, to support instrument flight rule (IFR) operations, and to bring the airspace into compliance with FAA orders.
The Federal Aviation Administration (FAA) announces a public meeting to solicit input on the modernization of pilot school regulations.

The FAA proposes to supersede Airworthiness Directive (AD) 2020-09-15, which applies to certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. AD 2020-09-15 requires removing the removable parts of the dual hoist installation or removing the de-icing system and allows, for certain helicopters, revising the rotorcraft flight manual (RFM) for the helicopter and installing a placard as an optional method of compliance. Since the FAA issued AD 2020-09-15, analysis revealed that additional vibration level measurements are necessary. This proposed AD would retain all the requirements of AD 2020-09-15 and would require for certain helicopters repetitively measuring vibration levels in-flight, and depending on the results, performing corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
This action proposes to amend restricted area R-5201, Fort Drum, NY. The purpose of this proposal is to modify the time of designation for restricted area R-5201 from "Continuous April 1 through September 30 and 0600 through 1800 hours local time, October 1 through March 31; other times by Notice to Airmen (NOTAM) 48 hours in advance" to be "continuous" to align with actual usage. This change does not add additional designated restricted area airspace.
The FAA proposes to supersede Airworthiness Directive (AD) 2023-01-04, which applies to all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. AD 2023-01-04 requires, for helicopters with certain part-numbered tail rotor head (TRH) spider pitch change units installed, inspecting the spider pitch change nut (nut) for correct installation; marking a 2 to 5 mm wide black paint index mark and repetitively inspecting the alignment of the marking; and performing additional inspections and corrective actions if necessary. Since the FAA issued AD 2023-01-04, new or more restrictive airworthiness limitations were issued, which terminated the requirement for the repetitive inspections of the black paint index marking. This proposed AD would require the same actions of AD 2023-01-04, except for the repetitive black paint index marking inspection and would prohibit installing certain parts unless certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.
