The FAA is issuing this AD to address the unsafe condition on these products.
This action removes Class E airspace extending upward from 700 feet above the surface for Sunbury Community Hospital Heliport, Sunbury, PA, which is abandoned and no longer in operation. Controlled airspace is no longer necessary for the safety and management of instrument flight rules (IFR) operations at this heliport.
The FAA is adopting a new airworthiness directive (AD) for all Dassault Aviation Model Falcon 7X airplanes. This AD was prompted by hydraulic leakage from the spoiler power control unit (SPPCU) in service. Relevant investigations determined that, following certain failures, the spoiler electrical control unit (SPECU) can deliver an untimely and permanent activation command to the SPPCU standby electrical pump, which can possibly result in overheating and significant hydraulic leakage of the unit. This AD requires replacing the affected SPECUs and prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is superseding Airworthiness Directive (AD) 2021-25- 14, which applied to all Airbus SAS Model A319-111, -112, -113, -114, - 115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, - 212, -213, -231, and -232 airplanes. AD 2021-25-14 required repetitive inspections for cracking at the wing manhole access panel attachment holes at certain wing skin panels, and corrective action if necessary. Since the FAA issued AD 2021-25-14, new investigation results determined that additional airplanes are subject to the unsafe condition and certain structural repair manual (SRM) tasks should not be used to accomplish repairs. This AD continues to require the actions in AD 2021-25-14. This AD also changes the applicability to both add and remove airplane models, updates the compliance times, and prohibits the use of certain SRM tasks for repair. The FAA is issuing this AD to address the unsafe condition on these products.
In an NPRM published in the Federal Register on May 30, 2025, FMCSA proposed to remove references to liquid-burning flares from the warning device requirements in the Federal Motor Carrier Safety Regulations. This proposed revision would remove outdated language referring to warning devices that FMCSA believes are no longer used. On June 5, 2025, FMCSA published a correction to address an error in the docket number, errors in the ADDRESSES section, and errors in the SUPPLEMENTARY INFORMATION section of the NPRM. Both the NPRM and subsequent correction contained an error in the regulation identification number (RIN).

The FAA proposes to supersede Airworthiness Directive (AD) 2023-08-04, which applies to certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2023-08-04 requires a detailed visual inspection of all door 1 and door 3 lavatory and galley potable water systems for any missing or incorrectly installed clamshell couplings, and applicable on-condition actions. Since the FAA issued AD 2023-08- 04, Boeing has discovered that some couplings did not have the required safety strap and has developed a design solution that replaces the couplings with couplings that have safety straps. This proposed AD would retain the requirements of AD 2023-08-04 and require, for certain airplanes, a detailed inspection of all clamshell couplings for the presence and correct installation of safety straps at door 1 and door 3 lavatories and galleys with a potable water system, and applicable on- condition actions, which would terminate the existing requirements. The AD would also prohibit the installation of affected parts at inspection locations. The FAA is proposing this AD to address the unsafe condition on these products.
FHWA, FRA, and FTA are publishing this interim final rule (IFR) to modify the regulations implementing the National Environmental Policy Act (NEPA) that apply to all three agencies to be consistent with the removal of regulations previously issued by the Council on Environmental Quality (CEQ), the amendments to NEPA included in the section of the Fiscal Responsibility Act of 2023 known as the Building United States Infrastructure through Limited Delays and Efficient Reviews (BUILDER) Act of 2023, and amendments regarding efficient environmental reviews included in the Infrastructure Investment and Jobs Act of 2021. This rule will become effective immediately while the agencies seek comment on what further changes may be appropriate.
This interim final rule rescinds the National Highway Traffic Safety Administration's (NHTSA) 1975 Procedures for Considering Environmental Impacts from the Code of Federal Regulations because they are outdated, because they were promulgated on the basis of authorities that have been rescinded, and because the Department of Transportation has promulgated updated Department-wide National Environmental Policy Act (NEPA) procedures that will guide NHTSA's NEPA process.
This action amends Class D and Class E airspace at Coastal Carolina Regional Airport, New Bern, NC, due to the current designated airspace not properly containing instrument flight rule operations. Additionally, this action amends Class E4 airspace at Coastal Carolina Regional Airport, New Bern, NC, due to portions no longer meeting the requirements of its designation. Lastly, this action amends the Class E5 airspace that no longer meets the requirements for its specific designation due to the amendment or cancellation of Standard Instrument Approach Procedures. Controlled airspace is necessary for the safety and management of IFR operations in the area for existing instrument approaches.
