The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This proposed AD was prompted by a determination that double overcoating sealant was not applied during production on certain fasteners in the center wing box (CWB) and belly faring junction for both left-hand (LH) and right-hand (RH) sides, and certain fasteners are also susceptible to rotation. This proposed AD would require replacing each affected part and applying additional head nut cap protection. The FAA is proposing this AD to address the unsafe condition on these products.
This action proposes to amend Class E5 airspace over Elizabeth City, NC. This action will add Class E airspace extending upward from 700 feet above the surface within a 6-mile radius of Sentara Albemarle Medical Center Heliport. This addition of airspace is necessary because of new instrument approach procedures that have been developed for the heliport.
This action proposes to amend Very High Frequency Omnidirectional Range (VOR) Federal Airway V-108 in the vicinity of Concord, California. The FAA is proposing this action due to the planned decommissioning of the Concord VOR/Distance Measuring Equipment (DME) navigational aid (NAVAID). This NAVAID is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports that the low range radio altimeter (LRRA) system has an increased rate of non-computed data (NCD) outputs at low altitudes during approach and landing, which could cause unreliable altimeter function. This proposed AD would require replacing the left and right LRRA transmit and receive coaxial cables with larger gauge coaxial cables. The FAA is proposing this AD to address the unsafe condition on these products.
This action amends Very High Frequency Omnidirectional Range (VOR) Federal Airways V-14, V-192, V-210, and V-221 in the vicinity of Muncie, Indiana. The FAA is taking these actions due to the planned decommissioning of the VOR portion of the Muncie, IN, VOR/Distance Measuring Equipment (DME) navigational aid (NAVAID). This NAVAID is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.
This action establishes United States Area Navigation (RNAV) Route Q-151 and revokes Jet Route J-517 in the northern United States. The FAA is taking these actions due to the lack of navigational signal coverage, restricting usage of J-517.
This action proposes to revoke Very High Frequency Omnidirectional Range (VOR) Federal Airway V-320 in Alaska due to navigational signal limits causing portions of this route to be unusable. There are two routes with the identifier V-320, one located in the state of Alaska and one located in the state of Michigan. This action only proposes to affect the V-320 located in Alaska. The FAA is also proposing to establish United States Area Navigation (RNAV) Route T-550 near Anchorage, AK.
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes. This AD was prompted by reports of in-flight events of excessive cabin and flight deck temperatures that could not be controlled by the flightcrew using existing procedures. This AD requires revising the existing airplane flight manual (AFM) to provide the flightcrew with operating procedures (non-normal checklists) if a certain circuit breaker in the standby power control unit (SPCU) trips. The FAA is issuing this AD to address the unsafe condition on these products.

This AD was prompted by a report of a quality escape for certain high-pressure compressor (HPC) stage 5 blisks manufactured from a single forged ingot with a nonconforming indication. This AD requires replacement of certain HPC stage 5 blisks with parts eligible for installation. 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.
The FAA is superseding Airworthiness Directive (AD) 2023-22- 11, which applied to certain Embraer S.A. (Embraer) Model EMB-505 airplanes. AD 2023-22-11 required repetitively replacing the clutch retaining bolt and washer of the aileron autopilot servo mount. Since the FAA issued AD 2023-22-11, the FAA has determined that the applicability should include certain Model EMB-505 airplanes and, for certain airplanes, an additional requirement is necessary for the initial replacement of the retaining bolt and washer. This AD incorporates these additional airplanes into the applicability, adds the additional requirement, and also provides an optional terminating action for the repetitive retaining bolt and washer replacement. The FAA is issuing 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.
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by a report that, during production, certain sealant installations within the center wing fuel tank did not receive required visual and adhesion inspections. This proposed AD would require a detailed inspection of certain sealant installations in the left, right, and center wing side-of-body areas, an adhesion test of the sealant, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
This action corrects the description of the appeals process for applicants or holders of an Inspection Authorization (IA) set forth in a prior Federal Register notice of policy. On August 4, 2011, the Federal Aviation Administration published a document in the Federal Register concerning a notice of policy to clarify the definition of "Actively Engaged" for the purposes of applying for or renewing an IA. That notification contained incorrect information regarding the appeals process for the denial of an IA application for initial issuance or renewal.
The FAA is superseding Airworthiness Directive (AD) 2024-08- 05, which applied to certain Airbus SAS Model A330-200, A330-200 Freighter, and A330-300 series airplanes; and Model A330-841 and A330- 941 airplanes. AD 2024-08-05 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2024-08- 05, the FAA has determined that additional new and more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2024-08-05 until the existing maintenance or inspection program, as applicable, is revised to incorporate the 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 Airbus Helicopters Model SA330J helicopters. This AD was prompted by a report that the measured resistance value of the pyrotechnic cartridge of the engine fire extinguisher was out of tolerance. This AD requires repetitively inspecting the pyrotechnical cartridge and, depending on the results of the inspection, accomplishing corrective actions. This AD also prohibits an affected pyrotechnical cartridge from being installed on any helicopter unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
This action establishes Class E airspace extending upward from 700 feet above the surface at Providence Seaside Hospital Heliport, Seaside, OR. This action supports instrument flight rules (IFR) operations at the heliport.
The FAA is superseding Airworthiness Directive (AD) 2025-07- 06, which applied to all Airbus Helicopters Model H160-B helicopters. AD 2025-07-06 required measuring the axial play of the rotating scissors spherical bearings and depending on the results, accomplishing corrective action and reporting inspection results. Since the FAA issued AD 2025-07-06 a determination was made that repetitive inspections for axial play measurements on non-rotating scissors spherical bearings are necessary. This AD retains all of the actions required in AD 2025-07-06 and extends the definition of an affected part to include all serial numbered non-rotating scissors spherical bearings. This AD also prohibits installing affected rotating and non- rotating scissors spherical bearings unless certain requirements are met. 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 all Airbus Helicopters Model H160-B helicopters. This proposed AD was prompted by reports of a fully discharged personal locator beacon (PLB) battery installed on an emergency life-raft system (ELRS), as well as a report where the ropes connecting the two ELRS to the PLB were not correctly attached. This proposed AD would require performing a functional test of the PLB and inspecting the rope connection to the ELRS. Depending on the results of the functional test, this proposed AD would require performing the functional test again or replacing affected parts, and depending on the results of the rope inspection, correctly attaching the wrist strap of the PLB to the ELRS rope. This proposed AD would also prohibit the installation of a certain part- numbered PLB and the rope connection to the ELRS, unless certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA proposes to supersede Airworthiness Directive (AD) 2025-06-01, which applies to all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2025-06-01 requires revising the existing airplane flight manual (AFM) to incorporate the procedures for the flightcrew to manually isolate the opposite functional engine in the event of an engine bleed duct large leak condition. Since the FAA issued AD 2025-06-01, an electronic engine control (EEC) software update has been developed to address the unsafe condition. This proposed AD would continue to require the actions in AD 2025-06-01 and would require installing a certain EEC software update on both engines. This proposed AD would also remove airplanes from 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 certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes.

FMCSA amends the Federal Motor Carrier Safety Regulations (FMCSR) to rescind the requirement that the rear impact guard be permanently marked or labeled with a certification from the impact guard manufacturer as required by the applicable Federal Motor Vehicle Safety Standard (FMVSS) promulgated by the National Highway Traffic Safety Administration (NHTSA). The certification label or marking provides motor carriers purchasing new trailers or new impact guards to replace damaged devices with a means to determine whether the equipment is certified as meeting the FMVSS. However, the labeling or marking requirement has proven problematic for motor carriers when the label or marking becomes illegible or wears off during the service life of the trailer or guard. This final rule eliminates an unintended regulatory burden on motor carriers without compromising safety, as it does not affect the applicable FMVSS. The final rule also rescinds a guidance document pertaining to illegible, incomplete, or missing rear impact guard certification labels.
FMCSA adds an exception for portable conveyors used in aggregate industry operations, and manufactured before 2010, from the requirement that each commercial motor vehicle (CMV) be equipped with brakes acting on all wheels, provided certain conditions are satisfied. This final rule responds to a petition for rulemaking from the Michigan Aggregates Association. The exception will provide relief from a regulatory requirement for certain portable conveyors without impacting safety.
FMCSA amends the emergency equipment rules to remove the requirement for commercial motor vehicles (CMVs) to be equipped with at least one spare fuse for each type and size of fuse needed for the operation of the CMV. This change will remove an unnecessary requirement from the Federal Motor Carrier Safety Regulations (FMCSR).
FMCSA amends the Federal Motor Carrier Safety regulations (FMCSR) to allow dual-status military technicians to qualify for the exception for certain military personnel from commercial driver's license (CDL) standards. Dual-status military technicians are civilian technicians employed by military units to provide day-to-day support such as training, maintenance, and other activities required to support the unit. They are required by statute to maintain membership in one of the Army or Air Force Reserve Components as a condition of their civilian employment.
FMCSA clarifies the requirement to complete a Driver Vehicle Inspection Report (DVIR) based upon a public comment filed by the National Tank Truck Carriers (NTTC). The DVIR may already be completed electronically, however the explicit language in this rule will make this clear. This will encourage motor carriers and drivers to utilize electronic, cost-saving methods when completing DVIRs.
FMCSA amends the requirements for commercial motor vehicle (CMV) tires to clarify that the Federal Motor Carrier Safety Regulations (FMCSR) do not require tire load restriction markings on the sidewalls of the tires. This change eliminates confusion and clarifies the scope of FMCSA's authority regarding requirements for CMV tires.
This action amends Class D, Class E2, Class E4, and Class E5 airspace at Patuxent River Naval Air Station (NAS) (Trapnell Field), Patuxent River, MD. The previously designated controlled airspace did not properly contain instrument flight rule (IFR) operations, which require controlled airspace. The geographic coordinates for Patuxent River NAS (Trapnell Field) are updated in the airspace legal descriptions. The references to the decommissioned Patuxent VORTAC are updated in the Class E2, Class E4, and Class E5 airspace legal descriptions. Last, the references to the decommissioned Patuxent River NDB are removed in the Class E2 and Class E4 airspace legal descriptions.
FMCSA amends the rules for emergency equipment on commercial motor vehicles (CMVs) to remove the references to liquid-burning flares from the warning device requirements in the Federal Motor Carrier Safety Regulations (FMCSR). This action eliminates outdated language referring to warning devices that FMCSA believes are no longer used.
