✈️New FAA Regulations on Standard Instrument Approach Procedures
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.

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Wyoming on December 30, 2022, and supplemented on August 31, 2023, and November 16, 2023, addressing regional haze for Jim Bridger Units 1 and 2 (Wyoming 2022 SIP revision). Wyoming's 2022 SIP revision provides oxides of nitrogen (NO<INF>X</INF>) emission and heat input limits that collectively allow for identical reasonable progress as part of the long term strategy during the first implementation period as the associated emission limits in the existing SIP for Jim Bridger Units 1 and 2. The EPA is also approving monthly and annual NO<INF>X</INF> and sulfur dioxide (SO<INF>2</INF>) emission limits for Jim Bridger Units 1 through 4 that were included in Wyoming's 2022 SIP revision. The EPA is taking this action pursuant to the Clean Air Act (CAA or the Act).

The Environmental Protection Agency (EPA) is proposing to approve the addition of Director's Final Findings and Orders (DFFOs) issued by the Ohio Environmental Protection Agency (Ohio EPA) to Carmeuse Lime, Inc. into the Ohio State Implementation Plan (SIP) for the 2010 sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS). The DFFOs establish a new emissions limit for SO<INF>2</INF> emissions from the combined lime kiln stack that receives and emits SO<INF>2</INF> emissions from two rotary lime kilns at the Carmeuse Lime Maple Grove Facility in Seneca County, Ohio.
Learn More✈️New FAA Airworthiness Directive for Boeing Aircraft - Compliance Required
The FAA is superseding Airworthiness Directive (AD) 2025-01- 06, which applied to all The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. AD 2025-01-06 required identifying the part number, and the serial number if applicable, of the Captain's and First Officer's seats and applicable on-condition actions for affected seats. AD 2025-01-06 also required a one-time detailed inspection and repetitive checks of the horizontal movement system (HMS) of the Captain's and First Officer's seats and applicable on-condition actions. Since the FAA issued AD 2025-01-06, the FAA determined that AD 2025-01-06 contains an error when providing conditions for taking credit using a previous revision of the service information. This AD requires the actions of AD 2025-01-06 and revises paragraph (j) of this AD to clarify which actions are not required. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️Proposed AD for CFM International LEAP Engines - Compliance Impact
The FAA proposes to supersede Airworthiness Directive (AD) 2018-19-16, which applies to all CFM International, S.A. (CFM) Model LEAP-1A23, -1A24, -1A24E1, -1A26, -1A26E1, -1A26CJ, -1A29, -1A29CJ, - 1A30, -1A32, -1A33, -1A33B2, and -1A35A engines with certain full authority digital engine control (FADEC) and prognostic health monitoring (PHM) software installed. AD 2018-19-16 requires removing certain FADEC and PHM software and installing versions eligible for installation. Since the FAA issued AD 2018-19-16, the manufacturer has developed a new pressure subsystem (PSS) with a heater element to evaporate potential moisture on the PSS manifold/transducer interface and prevent freezing at low temperature. This proposed AD would require replacing certain FADEC and PHM software with new versions that are eligible for installation, replacement of certain harnesses with newly designed harnesses, and replacement of the PSS with a newly designed heated PSS. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️FAA Proposes Airworthiness Directive for Dassault Falcon 7X
The FAA proposes to supersede Airworthiness Directive (AD) 2022-12-10, which applies to certain Dassault Aviation Model FALCON 7X airplanes. AD 2022-12-10 requires revising the existing airplane flight manual (AFM) to provide emergency procedures for inconsistent or unreliable flight data, emergency and abnormal operations procedures for the generic input/output (GEN I/O) internal module failure, and emergency procedures for additional information. AD 2022-12-10 also requires revising the existing minimum equipment list (MEL) for the multi-function probe heating, air data, and inertial reference systems. Since the FAA issued AD 2022-12-10, the manufacturer developed modifications that fix a weak point in the avionics architecture. This proposed AD would continue to require the actions in AD 2022-12-10 and would remove certain airplanes from the applicability. This proposed AD would also require modification of the avionics system and related revisions to the existing AFM and MEL. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Aerospace LP Model Gulfstream G150 airplanes. This AD was prompted by a determination that a new airworthiness limitation is necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate a new airworthiness limitation. The FAA is issuing this AD to address the unsafe condition on these products.

AD 2024-15-03 also required a one-time detailed inspection and repetitive checks of the horizontal movement system (HMS) for the Captain's and First Officer's seats and applicable on-condition actions. Since the FAA issued AD 2024-15-03, the FAA determined that AD 2024-15-03 contains an error when providing conditions for taking credit using a previous revision of the service information.

The Environmental Protection Agency (EPA) is taking final action to approve the Regional Haze State Implementation Plan (SIP) for the State of Iowa as satisfying applicable requirements under the Clean Air Act (CAA) and EPA's Regional Haze Rule (RHR) for the program's second implementation period. Iowa's SIP submission addresses the requirement that states must periodically revise their long-term strategies for making reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas. The SIP submission also addresses other applicable requirements for the second implementation period of the regional haze program. The EPA is taking this action pursuant to the CAA.
Learn More🚁New Airworthiness Directive for Bell Textron Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bell Textron Canada Limited (Bell) Model 427 helicopters. This proposed AD was prompted by a report of a cracked transmission oil check valve (check valve). This proposed AD would require inspecting and measuring certain check valves and, depending on the results, repetitively inspecting and removing the check valve from service if it has leaks or is cracked. This proposed AD would also prohibit installing the affected check valves on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
