The FAA proposes to adopt a new airworthiness directive (AD) for all Leonardo S.p.a. Model AB139, AW139, and AW189 helicopters. This proposed AD was prompted by a report of cracks on the left-hand (LH) and right-hand (RH) tube assemblies installed on the brake pedal assemblies. This proposed AD would require repetitively inspecting the LH and RH tube assemblies for Model AB139 and AW139 helicopters, and the LH and RH pedal shaft assemblies for Model AW189 helicopters, and depending on the results of the inspection, corrective actions. This proposed AD would also prohibit installing certain parts unless certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.
We, the U.S. Fish and Wildlife Service (Service), announce 90- day findings on 10 petitions to add species to the Lists of Endangered and Threatened Wildlife and Plants under the Endangered Species Act of 1973, as amended (Act). Based on our review, we find that the petitions to list the Alvord chub (Siphateles alvordensis), Donner und Blitzen pebblesnail (Fluminicola insolitus), gray cat's-eye (Oreocarya leucophaea), Mount Pinos sooty grouse (Dendragapus fuliginosus howardi), mysterious lantern firefly (Photuris mysticalampas), Olympic marmot (Marmota olympus), San Joaquin tiger beetle (Cicindela tranquebarica joaquinensis), stippled studfish (Fundulus bifax), Wilson's phalarope (Phalaropus tricolor), and wonder caddisfly (Neothremma prolata) present substantial scientific or commercial information indicating that the petitioned actions may be warranted. Therefore, with the publication of this document, we announce that we are initiating status reviews of these species to determine whether the petitioned actions are warranted. To ensure that the status reviews are comprehensive, we request scientific and commercial data and other information regarding the species and factors that may affect their status. Based on the status reviews, we will issue 12-month petition findings, which will address whether or not the petitioned actions are warranted, in accordance with the Act.
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters. This proposed AD was prompted by a determination that a certain part-numbered standard MS18027 type hook may be subject to localized yielding in the mating threads when assembled to higher assembly torques. This proposed AD would require modifying and re-identifying the affected part or replacing the affected part with a serviceable part. This proposed AD would also prohibit installing an affected part on any helicopter unless certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.
The Coast Guard is changing the operating schedule that governs the Dorset Avenue Bridge across Inside Thorofare, mile 72.1, at Ventnor City, NJ. The final rule will allow the drawbridge to only open between the hours of 11 p.m. to 7 a.m., if at least four hours' notice is given.
The Coast Guard is proposing to modify the Longview anchorage by reducing its size to allow completion of the Longview Channel realignment project.

By this final rule, the Census Bureau is removing its regulations governing the cutoff dates for the recognition of boundary changes for the 2010 Census. This action is necessary because the regulations pertain exclusively to the 2010 Decennial Census and are therefore obsolete, serving no current administrative or public purpose. The intended effect is to streamline the Code of Federal Regulations and reduce potential confusion for the public by removing outdated provisions.
By this rule, the Census Bureau (Bureau) is eliminating a part of the Code of Federal Regulations that consists solely of a single provision cross-referencing another part of the Code. This action is necessary to streamline and simplify the Bureau's regulations. The intended effect of this action is to reduce administrative clutter without altering any substantive rights or obligations.
The Census Bureau (Bureau) is removing its regulations related to the release of decennial census population information. Such regulations are obsolete and have not applied to the determination of methodology for calculating the tabulations of total population reported to states and localities under 13 U.S.C. 141(c) since the decennial census in 2000. This action is necessary to remove obsolete regulatory language, keep the Bureau's regulations current, and ensure that the Secretary of Commerce (Secretary) is able to fulfill his statutory obligations without being hindered by an unnecessary administrative process.
By this rule, the Census Bureau (Bureau) is amending its regulations that govern the furnishing of personal census data. Specifically, this rule removes two unnecessary sections that merely restate underlying statutory language. This action is necessary to reduce regulatory complexity and redundancy. The intended effect is to promote the simplicity and clarity of the Code of Federal Regulations for public benefit, without altering any substantive rights or obligations.
FAA is revising its regulations to implement certain flight restrictions in the airspace over the Potomac River near Ronald Reagan Washington National Airport (DCA) permanently. These revisions are necessary to mitigate the potential for midair collisions resulting from insufficient separation between fixed-wing aircraft operating to or from DCA and helicopters or powered-lift operating in the vertical- lift flight mode near DCA. The revisions will also fully implement a National Transportation Safety Board safety recommendation. The flight restrictions will prohibit helicopters and powered-lift operating in the vertical-lift flight mode from operating in a designated area near DCA unless these aircraft are conducting an essential operation.
The Coast Guard is establishing a temporary security zone for navigable waters within a 500-yard radius of vessel carrying cargo requiring an elevated level of security in the Corpus Christi and La Quinta Shipping Channels.

Entry of vessels or persons into this zone is prohibited unless specifically authorized by the Captain of the Port, Sector Corpus Christi.
The FAA proposes to supersede Airworthiness Directive (AD) 2023-11-05, which applies to all Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. AD 2023-11-05 requires revising the airworthiness limitations section (ALS) of the existing aircraft maintenance manual (AMM) or instructions for continued airworthiness (ICA) to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-11-05, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the ALS of the existing AMM or ICA for your airplane. The FAA is proposing this AD to address the unsafe condition on these products.
By this rule, the Census Bureau (Bureau) amends and removes certain regulations governing the program for challenging the Bureau's annual population estimates (Population Estimates Challenge Program). This action will improve and streamline the regulations by clarifying that part 90 pertains to requests to challenge the Bureau's annual population estimates, properly introducing an acronym used throughout part 90, eliminating inconsequential language, and amending or removing provisions that impose undue restrictions or requirements on potential challengers. The intended effect is to create a more efficient, clear, and accessible process for governmental units to request a challenge to the Bureau's population estimates, thereby promoting accuracy and accountability.
In this document, the Federal Communications Commission (FCC or Commission) adopts certain changes to its rules concerning Class A television, low power television and TV translator stations (LPTV Service).

By this rule, the Census Bureau (Bureau) is amending its regulations that govern the Bureau's official seal. Specifically, this rule removes unnecessary regulatory language and consolidates all of the necessary language into a single regulation. This action is intended to streamline the Bureau's regulations and promote clarity by eliminating redundancy and potential inconsistencies between the regulatory language and the underlying statutory language of 13 U.S.C. 3.
The Environmental Protection Agency (EPA) is proposing to determine that the Baltimore, Maryland nonattainment area (the Baltimore Area or the Area) has clean data for the 2015 8-hour ozone national ambient air quality standards (2015 ozone NAAQS or standard). This proposed clean data determination (CDD) under the EPA's Clean Data Policy is based upon quality-assured, quality-controlled, and certified ambient air quality monitoring data showing that the Baltimore Area has attained the 2015 ozone NAAQS based on 2022-2024 data available in the EPA Air Quality System (AQS) database. If finalized, this proposed CDD would suspend the obligations of the State of Maryland (MD) to submit certain attainment area planning requirements for as long as the Baltimore Area continues to attain the 2015 ozone NAAQS. As part of this rulemaking, the EPA also proposes to take final agency action on portions of exceptional events requests submitted by MD on February 2, 2024 and concurred on by the EPA on November 12, 2025. The proposed CDD is based upon the EPA's concurrence on portions of the exceptional events demonstrations. This action is being taken under the Clean Air Act (CAA).
The Coast Guard is establishing a temporary safety zone for navigable waters within a 50-yard radius of a portion of the St. Clair River, St. Clair, MI.
