✈️New FAA Airworthiness Directive on General Electric Engines
The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model CF6-80E1A2, CF6-80E1A3, CF6-80E1A4, and CF6-80E1A4/B engines. This AD was prompted by a manufacturer investigation that revealed certain high-pressure turbine (HPT) stage 1 and HPT stage 2 disks were manufactured from powder metal material suspected to contain iron inclusion. This AD requires replacement of affected HPT stage 1 and HPT stage 2 disks with parts eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.

This action amends domestic Very High Frequency Omnidirectional Range (VOR) Federal Airways V-7, V-35, V-157, V-159, and V-198 in the eastern United States. The FAA is taking this action due to the planned decommissioning of the Cross City, FL (CTY), VOR/ Tactical Air Navigation (VORTAC) and the Taylor, FL (TAY), VORTAC. This action is in support of the FAA's VOR Minimum Operational Network (MON) Program.

This action revokes Colored Federal Airway Amber 16 (A-16) in the northern United States. The FAA is taking this action due to the decommissioning of the White Rock, British Columbia (BC), Canada, Nondirectional Radio Beacon (NDB).
Learn More✈️Proposed Airworthiness Directive for Airbus SAS Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2020-06-18, which applies to all Airbus SAS Model A318 series airplanes; A319 series airplanes; A320-211, -212, -214, -216, -231, - 232, -233, -251N, -252N, -253N, -271N, -272N, and -273N airplanes; and A321 series airplanes. AD 2020-06-18 requires replacement of affected trimmable horizontal stabilizer actuators (THSAs) with serviceable THSAs. Since the FAA issued AD 2020-06-18, a new Airbus airplane model (A321-253NY) has been certified, on which affected parts could be installed in service. This proposed AD would continue to require the actions in AD 2020-06-18, would revise the applicability to include Model A321-253NY airplanes, and would prohibit the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️Proposed Airworthiness Directive for Airbus Airplanes Compliance
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A319-112 and -132 airplanes, and Model A320-214, -232, -233, -251N, and -271N airplanes. This proposed AD was prompted by rivet holes being left unplugged after bracket relocation or removal accomplished during certain modifications, potentially resulting in fatigue damage starting from those rivet holes. This proposed AD would require a one-time special detailed inspection (SDI) of the rivet holes and applicable corrective actions; and would also allow the installation of certain modifications, provided rivets are installed after the modification; as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Ohio State Implementation Plan (SIP). On November 6, 2024, the Ohio Environmental Protection Agency (Ohio EPA) submitted the state's plans for maintaining the 2008 ozone National Ambient Air Quality Standard (NAAQS or standard) in the Columbus, Ohio; Cleveland-Akron-Lorain, Ohio; and Cincinnati, Ohio-Kentucky-Indiana areas. EPA is proposing to approve these maintenance plans because they provide for the maintenance of the 2008 ozone NAAQS for each area for 10 additional years as required by the Clean Air Act (CAA). EPA is also initiating the adequacy review process for motor vehicle emission budgets (Budgets) for each area. This action, if finalized, would make certain commitments related to maintenance of the 2008 ozone NAAQS in these areas federally enforceable as part of the Ohio SIP.

The Environmental Protection Agency (EPA) is taking final action to approve a revision to the Mojave Desert Air Quality Management District (MDAQMD) portion of the California State Implementation Plan (SIP). This revision concerns emissions of oxides of nitrogen (NO<INF>X</INF>) from industrial, institutional, and commercial boilers, steam generators, and process heaters. We are approving a local rule that regulates these emission sources under the Clean Air Act (CAA or "Act").
Learn More🌫️EPA Approves Michigan's Sulfur Dioxide Compliance Plan
The Environmental Protection Agency (EPA) is approving the State Implementation Plan (SIP) revision submitted by Michigan on December 20, 2022, and supplemented on February 21, 2023, December 14, 2023, and April 2, 2024, which amends a SIP submission previously submitted to EPA on May 31, 2016, and June 30, 2016, for attaining the 2010 sulfur dioxide (SO<INF>2</INF>) primary national ambient air quality standard (NAAQS) for the Detroit SO<INF>2</INF> nonattainment area. This action follows a prior action which found that Michigan had satisfied emission inventory and new source review (NSR) requirements for this area but had not met requirements under the Clean Air Act (CAA) for the elements that EPA is approving here. This action also follows the promulgation of the 2022 Federal Implementation Plan (FIP) for the Detroit SO<INF>2</INF> nonattainment area.
Learn More✈️FAA Proposes Modification of Class E Airspace at Battle Mountain Airport
This action revises a notice of proposed rulemaking (NPRM) published in the Federal Register on January 7, 2025. As revised, this action proposes to modify the Class E airspace area designated as surface area, modify the Class E airspace area designated as an extension to a Class D or Class E surface area, and modify the Class E airspace extending upward from 700 feet or more above the surface of the earth at Battle Mountain Airport, Battle Mountain, NV. Additionally, this action proposes administrative amendments to update the airport's existing Class E airspace legal descriptions. These actions would support the safety and management of instrument flight rules (IFR) operations at the airport.
