This action amends the Class E airspace extending upward from 700 feet above the surface designated for Hagerstown, MD, by updating the reference to the St. Thomas Very High Frequency Omnidirectional Range Station and Tactical Air Navigation System (VORTAC) to show it as the St. Thomas Tactical Air Navigation System (TACAN). This action supports the safety and management of instrument flight rule (IFR) operations in the area.
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 National Highway Traffic Safety Administration is issuing this interpretive rule to set forth the agency's interpretation of the factors the agency is prohibited by law from considering when setting maximum feasible fuel economy standards under the Energy Policy and Conservation Act of 1975, the Energy Independence and Security Act of 2007, and other applicable law. This rule describes NHTSA's interpretation of its authority to establish the necessary legal foundation for bringing the Corporate Average Fuel Economy (CAFE) program into compliance with relevant statutory requirements. The rule also describes NHTSA's interpretation of its authority for a commercial medium- and heavy-duty (MDHD) on-highway vehicle and work truck fuel efficiency improvement program, also establishing the necessary legal foundation for bringing that program into compliance with the law. Pending the rulemaking process for the establishment of replacement standards, NHTSA will exercise its enforcement authority with regard to all existing CAFE and MDHD standards in accordance with the interpretation set forth in this rule.
The FAA is superseding Airworthiness Directive (AD) 2020-03- 14, which applied to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-03-14 required an inspection of affected crew oxygen cylinder assemblies for any discrepancy and replacement of discrepant crew oxygen cylinder assemblies with serviceable parts, and allowed installation of affected parts under certain conditions. Since the FAA issued AD 2020-03-14, the supplier introduced an improved crew oxygen cylinder assembly, that will ensure the correct function of the system. This AD continues to require the actions in AD 2020-03-14, requires replacement of all affected parts with redesigned parts, and also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.

This AD requires revising the limitations and normal procedures sections of the existing airplane flight manual (AFM). The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. The AD applies to certain The Boeing Company Model 787-9 and 787-10 airplanes. As published, a reference to the Alternative Methods of Compliance (AMOCs) paragraph in the regulatory text is incorrect. This document corrects that error. In all other respects, the original document remains the same.
This action corrects a final rule published by the FAA in the Federal Register on May 2, 2025. That final rule amended Class E airspace extending upward from 700 feet above the surface for ECU Health Edgecombe Heliport, Tarboro, NC, to accommodate new area navigation (RNAV) global positioning system (GPS) standard instrument approach procedures serving the heliport. That earlier final rule also updated the coordinates to reflect the most current and accurate location for Tarboro Edgecombe Airport. However, the updated coordinates were incorrect. Therefore, this action corrects that final rule by revising the coordinates.
The FAA is superseding Airworthiness Directive (AD) 2024-19-11 for all Robinson Helicopter Company Model R44 and R44 II helicopters. AD 2024-19-11 required visually inspecting a certain flex plate assembly (flex plate) and certain clutch shaft forward yokes (yokes), including each flex plate bolt, and depending on the results, taking corrective actions. AD 2024-19-11 also required removing certain yokes from service within a specified threshold, or as an alternative, performing in-depth inspections. Since the FAA issued AD 2024-19-11, it has been determined that clarifications regarding the alternative inspections are necessary. This AD requires the actions of AD 2024-19- 11 and clarifies that the alternative inspections are repetitive and adds a particular paint remover option to use when performing those alternative inspections. 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. The NPRM contained an error in the docket number, errors in the ADDRESSES section, and errors in the SUPPLEMENTARY INFORMATION section.
These special conditions are issued for a supplemental type certificate (STC) to install non-rechargeable lithium batteries and battery systems on certain transport-category airplanes. These airplanes, as modified by Delta Flight Products, will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is non-rechargeable lithium batteries and battery system installed in emergency locator transmitters (ELTs). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
