🌫️Proposed California Air Quality Permits
The Environmental Protection Agency (EPA) is proposing approval of six permitting rules, and limited approval and limited disapproval for one permitting rule, submitted on January 7, 2025, as a revision to the Antelope Valley Air Quality Management District (AVAQMD or "District") portion of the California State Implementation Plan (SIP). These revisions concern the District's New Source Review (NSR) permitting program for new and modified sources of air pollution under part D of title I of the Clean Air Act (CAA or "Act"). The submitted rules address deficiencies identified in a previous limited disapproval action and incorporate other revisions related to NSR requirements. If finalized, this action will update the AVAQMD's current SIP with the revised rules. We are taking comments on this proposal and plan to follow with a final action. Elsewhere in this Federal Register, we are making an interim final determination that will stay or defer the imposition of CAA sanctions associated with our previous limited disapproval action.
Learn More✈️Proposed Airworthiness Directive for Airbus A350 Aircraft
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by a determination that the applicable aircraft flight manual (AFM) was providing an incorrect value for maximum cumulative taxi time in freezing fog conditions. This proposed AD would require revising the existing AFM to provide the flightcrew with normal procedures to follow under certain conditions, 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 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.

The Environmental Protection Agency (EPA) is making an interim final determination that the California Air Resources Board (CARB) has submitted a Clean Air Act (CAA or "Act") state implementation plan (SIP) revision on behalf of the Antelope Valley Air Quality Management District (AVAQMD or "District") that corrects deficiencies concerning the District's New Source Review (NSR) stationary source permitting program. This determination is based on a proposed approval, published elsewhere in this issue of the Federal Register, of AVAQMD Rules 1301, 1302 (except 1302(C)(5) and 1302(C)(7)(c)), 1303, 1304, 1305, and 1309. The effect of this interim final determination is to stay the application of the offset sanction and to defer the action of the highway sanction that were triggered by the EPA's limited disapproval of AVAQMD Rules 1301, 1302 (except 1302(C)(5) and 1302(C)(7)(c)), 1303, 1304, 1305, 1309 on July 3, 2023.

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 a report that incorrect information was found in certain calculation tables in a section of the airplane flight manual (AFM) that addresses certain slat-flap conditions. This proposed AD would require revising the Non-Normal Procedures section of the existing AFM to provide the flightcrew with corrected procedures to use in certain slat-flap conditions. 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.

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.

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.
