✈️Proposed Airworthiness Directive for Embraer EMB-505 Airlines
The FAA proposes to supersede Airworthiness Directive (AD) 2023-22-11, which applies to certain Embraer S.A. (Embraer) Model EMB- 505 airplanes. AD 2023-22-11 requires repetitively replacing the clutch retaining bolt and washer of the aileron autopilot servo mount. Since the FAA issued AD 2023-22-11, the FAA has determined that the applicability should be expanded to include all Model EMB-505 airplanes and, for certain airplanes, an additional requirement is necessary for the initial replacement of the retaining bolt and washer. This proposed AD would also provide an optional terminating action for the repetitive retaining bolt and washer replacement. These actions are specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to remove Class D and E4 airspace at Phillips Army Airfield (AAF) due to the closure of the air traffic control tower. This action proposes to establish Class E2 airspace extending upward from the surface above Phillips AAF, Aberdeen, MD, at the request of the United States Army to provide the required airspace for Instrument Flight Rules (IFR) operations at Phillips AAF. This action also proposes to amend Class E5 airspace to accommodate the decommissioning of Aberdeen non-directional radio beacon (NDB), and cancellation of the associated instrument approach procedures. Controlled airspace is necessary for the safety and management of IFR operations in the area for existing instrument approaches.

The Environmental Protection Agency (EPA) is proposing to approve a revision to the Placer County Air Pollution Control District (PCAPCD or "District") portion of the California State Implementation Plan (SIP). This revision concerns the District's Clean Air Act (CAA or "Act") nonattainment new source review permitting program that regulates construction and modifications of major stationary sources of air pollution in nonattainment areas. We are proposing to approve a local rule that has been revised to address deficiencies previously identified by the EPA in a prior action that included a limited approval/limited disapproval of a prior version of the rule. 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 defer the imposition of CAA sanctions associated with our previous limited disapproval.

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 Placer County Air Pollution Control District (PCAPCD or "District") that corrects deficiencies concerning the District's nonattainment new source review stationary source permitting program. This determination is based on a proposed approval, published elsewhere in this issue of the Federal Register, of PCAPCD Rule 502, "New Source Review." The effect of this interim final determination is to defer sanctions that were triggered by the EPA's previous limited disapproval of PCAPCD Rule 502 in 2023.
Learn More✈️Amendments to Standard Instrument Approach Procedures Effective April 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✈️New Airworthiness Directives for Airbus A350 Aircraft by FAA
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and A350-1041 airplanes. This AD was prompted by a report indicating that the thrust reverser and pylon thermal blankets were found damaged due to air leaking from the pre-cooler exchanger (PCE). This AD requires repetitively testing the PCE for air leaks and reporting the results, and, depending on findings, inspecting the thermal blankets for damage and replacing the PCE, 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.

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✈️FAA Proposes Airworthiness Directive for Boeing 757 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757 airplanes. This proposed AD was prompted by reports of precoolers that failed due to a wear-out condition, combined with latently failed overheat detection thermal switches. This proposed AD would require an inspection for heat damage on the engine strut structure, repetitive tests of the thermal switch temperature and ground wires, replacement of the precooler on Model 757-300 airplanes, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️Proposed Removal of Class E Airspace in Sunbury, PA
This action proposes to amend Class E airspace extending upward from 700 feet above the surface for Sunbury, PA, by removing airspace for Sunbury Community Hospital Airport, Sunbury, PA, which is abandoned and no longer in operation. Controlled airspace is no longer necessary for the safety and management of instrument flight rules (IFR) operations at this heliport.
Learn More✈️Proposed FAA Airworthiness Directive for Airbus Canada Airplanes
The FAA is revising a notice of proposed rulemaking (NPRM) that would have applied to all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. This action revises the NPRM by adding a prohibition on flight dispatch under certain conditions. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, the FAA is requesting comments on this SNPRM.
