🚁New FCC Spectrum Rules for Uncrewed Aircraft Systems
In this document, the Federal Communications Commission (FCC or Commission) enables Uncrewed Aircraft System (UAS) operators to access dedicated spectrum for control-related communications. Specifically, this document adopts service rules under new rule part 88 that provide operators the ability to obtain direct frequency assignments in a portion of the 5030-5091 MHz band for non-networked operation. Under these rules, one or more dynamic frequency management systems (DFMSs) will manage and coordinate access to the spectrum and enable its safe and efficient use, by providing requesting operators with temporary frequency assignments to support UAS control link communications with a level of reliability suitable for operations in controlled airspace and other safety-critical circumstances. To address concerns regarding the impact of these aeronautical operations on adjacent services, this document locates these operations, for now, in the central part of the band, with substantial separation from the bands adjacent to the 5030- 5091 MHz band.

The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model GVII-G500 and GVII-G600 airplanes. This AD was prompted by a report of cracking in the electrical grounding receptacles located on the left and right wings. This AD requires inspecting the electrical grounding receptacles for cracks and corrosion, performing applicable on-condition actions, and sealing over the grounding receptacles on the top of the wings to permanently disable the receptacle. 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.

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 767-200, -300, and -300F airplanes. This AD was prompted by a report of a main landing gear (MLG) collapse event following maintenance where a grinder was operating outside of its input parameters, resulting in possible heat damage to the outer cylinder of the MLG. This AD requires replacing affected outer cylinders. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️FAA Final Rule on Instrument Approach Procedures Effective January 2025
This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures 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 for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
Learn More🌍EPA Defers Sanctions
The Environmental Protection Agency (EPA) is making an interim final determination that the State of Alaska has submitted state implementation plan (SIP) revisions that satisfy outstanding Clean Air Act requirements. This interim final determination defers the imposition of sanctions for the 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) Fairbanks North Star Borough PM<INF>2.5</INF> nonattainment area. This determination is based on a proposed approval, published in the "Proposed Rules" section of this Federal Register, of the 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 PM<INF>2.5</INF> national ambient air quality standards (NAAQS).

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.
