✈️Proposed Airworthiness Directive for Embraer S.A. Airplanes by FAA
The FAA proposes to adopt a new airworthiness directive (AD) for all Embraer S.A. Model EMB-545 and EMB-550 airplanes. This proposed AD was prompted by a jamming failure of the main door lock sensor. This proposed AD would require repetitive main door sensor operational tests, repetitive lubrication of the main door sensor mechanism, and on-condition actions, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD. The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to amend Class D airspace extending upward from the surface to and including 2,500 feet MSL within a 4.5- mile radius of William P. Gwinn Airport, beginning at the 205[deg] bearing from the airport clockwise to the 145[deg] bearing, thence to the beginning point. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A300 B4-600, B4-600R, and F4-600R series airplanes; and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, 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 BAE Systems Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2023-02-06, which applies to all BAE Systems (Operations) Limited Model 4101 airplanes. AD 2023-02-06 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-02-06, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require certain actions in AD 2023-02-06 and require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.

The Environmental Protection Agency (EPA) is reopening the public comment period on the proposed rule entitled "Air Plan Approval; AK, Fairbanks North Star Borough; 2006 24-hour PM<INF>2.5</INF> Serious Area and 189(d) Plan" published on January 8, 2025. Commenters requested more time to review the proposal and prepare comments. In response, the EPA is providing an additional 30 days for the public to provide comment on all aspects of the proposed rule. The January 8, 2025, notice of proposed rulemaking also started the EPA's adequacy process for the motor vehicle emissions budgets and began the public comment period for that process. The EPA is not reopening the public comment period for the adequacy process, and it intends to proceed with the adequacy process outside of this rulemaking.

The Environmental Protection Agency (EPA) is approving a revision to the State of New York's State Implementation Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) related to a Source-specific SIP (SSSIP) revision for Knowlton Technologies LLC, located at 213 Factory Street, Watertown, New York (the Facility). The control options in this SSSIP revision address volatile organic compound (VOC) Reasonably Available Control Technology (RACT) for the Facility source identified as two 10,000-gallon underground storage tanks holding virgin methanol. This action is being taken in accordance with the requirements of the Clean Air Act (CAA) for implementation of the 2008 and 2015 ozone NAAQS. The EPA proposed to approve this rule on November 26, 2024, and received no comments. This final action will not interfere with ozone NAAQS requirements and meets all applicable requirements of the CAA.

The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. As published, the service information referenced in certain paragraphs of the regulatory text is incorrect, and the dates specified in the "System Airworthiness Limitation No. 3--Fan Blade Out Conditions" text and "System Airworthiness Limitation No. 4--Engine Nacelle Maintenance Errors" text of figure 1 to paragraph (j) of the regulatory text are incorrect. This document corrects those errors. In all other respects, the original document remains the same.
Learn More✈️FAA Airworthiness Directive for MHI RJ Aviation on 5G Interference
The FAA is adopting a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 and 440), CL-600-2C10 (Regional Jet Series 700, 701, and 702), CL-600- 2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by the determination that radio altimeters cannot be relied upon to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3.98 GHz frequency band (5G C-Band). This AD requires installing a new radio frequency (RF) bandpass filter on the coaxial line between the radio altimeter and the receive antenna in the aft equipment compartment. The FAA is issuing this AD to address the unsafe condition on these products.
