✈️New Airworthiness Directive for General Electric Engines Overview
The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model GEnx-1B64, GEnx-1B64/P1, GEnx-1B64/P2, GEnx-1B67, GEnx-1B67/P1, GEnx-1B67/P2, GEnx-1B70, GEnx- 1B70/75/P1, GEnx-1B70/75/P2, GEnx-1B70/P1, GEnx-1B70/P2, GEnx-1B70C/P1, GEnx-1B70C/P2, GEnx-1B74/75/P1, GEnx-1B74/75/P2, GEnx-1B76/P2, GEnx- 1B76A/P2, GEnx-2B67, GEnx-2B67B, and GEnx-2B67/P engines. This AD was prompted by a manufacturer evaluation that determined a lower life limit may be necessary for certain stages 6-10 compressor rotor spools than allowed by the engine shop manual (ESM). This AD requires a one- time inspection of the stages 6-10 spools for previously accomplished blend repairs, a one-time inspection of the blend repairs on the stages 6-10 spools for compliance with the updated allowable limits, and replacement if necessary. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Defense and Space S.A. Model CN-235, CN-235-200, and CN-235-300 airplanes. This AD was prompted by a torn bulkhead seal found jamming the nose landing gear (NLG) emergency cable pulley. Due to the similarity of design, the main landing gear (MLG) emergency cable pulley could be exposed to the same failure mode. This AD requires repetitive inspections and corrective actions for damage of affected bulkhead seals and retainer rings, and repetitive replacement of affected parts, as 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 Environmental Protection Agency (EPA) is proposing to approve the state implementation plan (SIP) revisions submitted by the State of Alaska (Alaska or the State) on December 4, 2024, to address Clean Air Act requirements for the 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards in the Fairbanks North Star Borough Serious PM<INF>2.5</INF> nonattainment area. Alaska's submission includes SIP revisions to meet nonattainment planning requirements for emissions inventories, modeling and sulfur dioxide precursor demonstration for major stationary sources, control measures, attainment projections and progress to attainment and associated motor vehicle emissions budgets, and contingency measures. The EPA is also starting the adequacy process for the budgets.
Learn More✈️New FAA Regulations on Instrument Approach Procedures Effective 2025
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.
Learn More✈️Airworthiness Directive for CFM LEAP-1B Engines
The FAA is adopting a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) Model LEAP-1B engines. This AD was prompted by a report of a quality escape involving certain high- pressure compressor (HPC) stage 2 seals manufactured without detailed finish machining, which could result in deeper rubs and mechanical damage to the seal teeth of the stage 3-4 compressor rotor blisk (stage 3-4 blisk) of the mating compressor rotor during initial operation. This AD requires a visual inspection of the HPC stage 2 seal, a visual inspection of the forward arm seal teeth of the stage 3-4 blisk, an eddy current inspection (ECI) of the forward arm seal teeth of the stage 3-4 blisk, and replacement of the HPC stage 2 seal and the stage 3-4 blisk, if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More🏭New Regulations for Energy Efficiency in Central Air Conditioners
This final rule amends the Federal test procedure for central air conditioners and heat pumps ("CAC/HPs") to incorporate by reference the latest versions of the applicable industry standards. Specifically, DOE is incorporating by reference the latest version of the relevant industry consensus test standard, AHRI 210/240-2024 (I-P) for the current test procedure for CAC/HPs ("appendix M1") for measuring the current cooling and heating metrics--seasonal energy efficiency ratio 2 ("SEER2") and heating seasonal performance factor 2 ("HSPF2"). DOE is incorporating by reference the new industry consensus test standard, AHRI 1600-2024 (I-P), for a new test procedure ("appendix M2") for CAC/HPs that adopts two new metrics--seasonal cooling and off-mode rating efficiency ("SCORE") and seasonal heating and off-mode rating efficiency ("SHORE"). Testing to the SCORE and SHORE metrics would not be required until such time as compliance is required with any amended energy conservation standard based on the new metrics. Additionally, DOE is amending certain provisions of DOE's regulations related to representations and enforcement for CAC/HPs.
Learn More🚗New Federal Standards for Child Restraint Systems by 2025
This final rule amends Federal Motor Vehicle Safety Standard (FMVSS) No. 225; Child restraint systems, and FMVSS No. 213b; Child restraint systems, to improve ease-of-use of the lower and tether anchorages, improve correct use of child restraint systems in vehicles, and maintain or improve the correct use and effectiveness of child restraint systems (CRSs) in motor vehicles. This final rule fulfills a mandate of the Moving Ahead for Progress in the 21st Century Act (MAP- 21) requiring that NHTSA improve the ease-of-use for lower anchorages and tethers in all rear seat positions.

This action proposes to modify the Class E airspace area designated as surface area, establish a Class E airspace area designated as an extension to a Class D or Class E surface area, modify Class E airspace extending upward from 700 feet above the surface of the earth, and remove Class E airspace extending upward from 1,200 feet above the surface 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.

This action proposes to establish Class E airspace extending upward from 700 feet above the surface and revoke Class E airspace extending from 1,200 feet above the surface at Blanding Municipal Airport, Blanding, UT. Additionally, this action proposes administrative amendments to update the airport's legal description. These actions would support the airport's current instrument flight rules (IFR) operations that lack containment.
Learn More✈️FAA Proposes Airworthiness Directive for Bombardier Air
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports of engine-driven pump hydraulic pressure hoses for hydraulic systems number 1 and 2 chafing against the pylon in the aft equipment bay. This proposed AD would require an inspection of the engine-driven pump pressure hoses for any damage and minimum clearance between the engine-driven pump hydraulic pressure hose and case drain, suction pressure hose, and surrounding pylon structure; and corrective actions if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
