The FAA is superseding Airworthiness Directive (AD) 2023-26- 05, which applied to certain Pilatus Aircraft Ltd. (Pilatus) Model PC- 24 airplanes. AD 2023-26-05 required periodic replacement of affected titanium threaded bolts, a one-time inspection of the rudder mass balance arm and other elements of the rudder trim tab installation for correct attachment, damage (gouges), cracks, deformation, surface finish, and corrosion on any surrounding parts and, depending on findings, the accomplishment of applicable corrective actions. Since the FAA issued AD 2023-26-05, it was determined that some batches of titanium bolts had variations in the microstructure that could affect the fatigue characteristics. This AD requires replacing affected short rudder-trim control rod assemblies with serviceable rudder-trim control rod assemblies having threaded steel bolts and prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for Cameron Balloons Ltd. (Cameron) fuel cylinders fitted with certain pressure relief valve (PRV) adaptors on hot air balloons. This AD was prompted by the discovery of cracks on the upper hex portion of PRV adaptors. This AD requires repetitively visually checking the PRV adaptor for cracks and removing any fuel cylinder with a cracked PRV adaptor from service. The FAA is issuing this AD to address the unsafe condition on these products.
The Office of Hearings and Appeals (OHA) is issuing this document to correct the interim final rule published on January 10, 2025. These corrections address comments provided by the Office of the Federal Register regarding amendatory language and grammatical and technical errors that OHA identified in the published interim final rule.
The Office of Personnel Management (OPM) is proposing a rule to abolish the Hennepin, Minnesota, nonappropriated fund (NAF) Federal Wage System (FWS) wage area and define most of its counties to the nearest NAF FWS wage areas. Those counties without NAF FWS employment would no longer be defined to a NAF wage area. These changes are necessary because NAF FWS employment in the survey area has been declining, and the local activities no longer have the capability to conduct local wage surveys.
The United States Patent and Trademark Office (USPTO) issues this final rule to implement an amendment to the Regulations under the Protocol Relating to the Madrid Agreement Concerning the International Registration of Marks (Madrid Protocol) adopted by the Madrid Union Assembly that went into effect on February 1, 2021, with a delayed implementation date of February 1, 2025. This final rule modifies U.S. trademark regulations addressing the replacement of a national registration or registrations by an international registration to allow for submission of partial replacement requests, in alignment with the Madrid Protocol, and to require a listing of the goods and/or services for which replacement is requested.
The Coast Guard is establishing a temporary safety zone one nautical mile in all directions around well #59 at approximate position 29[deg]04'28.919" N, 089[deg]10'48.720" W, near the Pass A Loutre State Wildlife Management Area. The safety zone is needed to protect persons and critical infrastructure from the potential contamination due to an oil spill in the Gulf of America. Entry of vessels or persons into this zone, or movement of vessels within this zone is prohibited unless specifically authorized by the Captain of the Port or a designated representative.
The FAA proposes to adopt a new airworthiness directive (AD) for certain Pratt & Whitney (PW) Model F117-PW-100, PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2143, and PW2643 engines. This proposed AD was prompted by an updated analysis of an event involving an International Aero Engines, LLC (IAE LLC) Model PW1127GA-JM engine, which experienced a high-pressure compressor (HPC) 7th-stage integrally bladed rotor (IBR-7) separation that resulted in an engine shutdown and aborted takeoff. This proposed AD would require repetitive angled ultrasonic inspections (AUSIs) of certain high-pressure turbine (HPT) 1st-stage disks and turbine hubs for any crack indications, and if necessary, removal from service and replacement, and removal from service of certain HPT lenticular seal assemblies. 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 Helicopters Model AS 332L2 and EC 225LP helicopters. This proposed AD was prompted by reports of overlengthened and deformed attachment bolts installed on the link of the main gearbox (MGB) suspension bar attachment bracket. This proposed AD would require replacing certain attachment bolts on the MGB suspension bar fittings, inspecting the removed bolts, and reporting the results of this inspection to Airbus Helicopters. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA proposes to supersede Airworthiness Directive (AD) 2024-10-13, which applies to all Airbus Helicopters Model AS332C, AS332C1, AS332L, AS 332L1, AS 332L2, and EC 225LP helicopters. AD 2024- 10-13 requires visually inspecting the bowls of the left-hand (LH) and right-hand (RH) fuel filters for any cracks and seepage. Depending on the inspection results, AD 2024-10-13 requires removing an affected fuel filter from service and replacing that part. AD 2024-10-13 also allows a certain fuel filter to be installed on any helicopter if certain actions are accomplished. Since the FAA issued AD 2024-10-13, additional inspection criteria was developed. This proposed AD would require the same actions as AD 2024-10-13 but would remove some helicopters from the applicability, add an inspection of the inner surface of the fuel filter bowls, and revise the tightening torque. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. This AD was prompted by a report of a sliding door that was locked in the open position detaching from the helicopter during flight. This AD requires modifying certain upper rail rollers, installing a label on each sliding door, and prohibits installing affected upper rail rollers or a door having an affected upper rail roller. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
The Food and Drug Administration (FDA, the Agency, or we) is classifying the device to detect bacterial protease activity in chronic wound fluid into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for the device to detect bacterial protease activity in chronic wound fluid's classification. We are taking this action because we have determined that classifying the device into class II (special controls) will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients' access to beneficial innovative devices in part by reducing regulatory burdens.
The Coast Guard will enforce a safety zone for the Duluth Fourth Fest Fireworks Display from 9:30 p.m. to 11 p.m. on July 4, 2025 to provide for the safety of life on navigable waterways during this event in the vicinity of Bayfront Park. During the enforcement period, entry into, transiting, or anchoring within the safety zone is prohibited unless authorized by the Captain of the Port (COTP) Marine Safety Unit Duluth or a designated representative.
This action changes the referenced Notice to Air Missions to Notice to Airmen in the airspace description for both the Class D and E airspace at Northeast Philadelphia Airport, Philadelphia, PA. This action does not change the airspace boundaries or operating requirements.
This action amends Class D airspace and establishes Class E airspace extending upward from the surface above Robins AFB, Warner Robins, GA, as the air traffic control tower will shift to part-time operations. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
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 document is a request for information (RFI) regarding the prescription drug machine-readable file disclosure requirements in the Transparency in Coverage final rules. The Departments of Labor, Health and Human Services (HHS), and the Treasury (the Departments) are issuing this RFI to gather input regarding implementation of the prescription drug machine-readable file disclosure requirements under the Transparency in Coverage final rules, including what modifications to the disclosure requirements or additional technical implementation guidance might be necessary to better ensure the accurate and timely completion of the prescription drug file.
This action removes Class D and E4 airspace at Phillips Army Airfield (AAF), Aberdeen, MD, due to the closure of the air traffic control tower. This action establishes Class E2 airspace extending upward from the surface above Phillips AAF at the request of the United States Army to provide the required airspace for Instrument Flight Rules (IFR) operations at Phillips AAF. This action also amends Class E5 airspace to accommodate the decommissioning of the Aberdeen non-directional radio beacon (NDB) and cancellation of the associated instrument approach procedures. Controlled airspace is necessary for the safety and management of IFR operations in the area for existing instrument approaches.

FMCSA proposes to amend the Federal Motor Carrier Safety Regulations (FMCSRs) to rescind the in-vehicle electronic logging device (ELD) operator's manual requirement for commercial motor vehicles (CMVs). FMCSA currently maintains a list of the ELD vendors who have self-certified their products including submission of the operator's manual. Additionally, drivers are required to understand the operation of the ELD on the vehicle. There is no readily apparent benefit to continuing to require that the users' manual be in the CMV. This proposal would eliminate an unintended regulatory burden on motor carriers without compromising safety.
The FAA is superseding Airworthiness Directive (AD) 2025-07- 04, which applied to all Airbus Canada Limited Partnership Model BD- 500-1A11 airplanes. AD 2025-07-04 required a review and disposition of all existing repairs and damage assessments for affected structure, corrective actions if necessary, and the prohibition of certain repair engineering orders (REOs). Since the FAA issued AD 2025-07-04, the FAA determined that the list of acceptable generic repair engineering orders (GREOs) specified in table 1 to paragraph (h)(3) of AD 2025-07- 04 was added in error. This AD continues to require review and disposition of all existing repairs and damage assessments for affected structure, which includes GREOs that were identified in AD 2025-07-04, corrective actions if necessary, and the prohibition of certain REOs. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA proposes to supersede Airworthiness Directive (AD) 2013-08-08, which applies to certain The Boeing Company Model 737-600 series airplanes. AD 2013-08-08 requires repetitive inspections for cracking of the fuselage skin at certain locations at chem-mill steps, and repair if necessary. AD 2013-08-08 also provides optional terminating action for the repetitive inspections. Since the FAA issued AD 2013-08-08, Boeing has reported that the compliance times are not adequate because new fleet data indicates that crack growth is faster and more distributed between tear straps, resulting in longer cracks than originally observed in the test data that prompted AD 2013-08-08. This proposed AD would continue to require the actions in AD 2013-08- 08, at reduced initial compliance times and repetitive intervals for the inspections, and mandate post-modification inspections if the optional modification is accomplished. The FAA is proposing this AD to address the unsafe condition on these products.
FHWA is proposing to rescind the rule and regulations issued on September 30, 1974, Federal-Aid Contracts (Appalachian Contracts).
NHTSA is proposing to remove the obsolete Federal Motor Vehicle Safety Standard (FMVSS) No. 216, related to roof crush resistance.
This action withdraws the notice of proposed rulemaking (NPRM) published in the Federal Register on May 21, 2015 proposing amendments to Federal Motor Vehicle Safety Standard (FMVSS) No. 218, "Motorcycle Helmets." The NPRM proposed three main changes to FMVSS No. 218: adding a definition of motorcycle helmet, adding preliminary screening requirements, and adding an alternate compliance process. Based on NHTSA's analysis of the comments received and other considerations, the Agency has decided to withdraw the rulemaking proposal.
FHWA proposes to rescind the regulations issued regarding the Forest Highway Program.
The Food and Drug Administration (FDA, the Agency, or we) is classifying the anti-mullerian hormone test system into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for the anti-mullerian hormone test system's classification. We are taking this action because we have determined that classifying the device into class II (special controls) will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients' access to beneficial innovative devices, in part by reducing regulatory burdens.
NHTSA is proposing to remove obsolete requirements from Federal Motor Vehicle Safety Standard (FMVSS) No. 214, Side impact protection.
