⚡New Standards for Business Practices in Public Utilities
The Federal Energy Regulatory Commission amends its regulations to incorporate by reference, with certain exceptions, the latest version (Version 004) of the Standards for Business Practices and Communication Protocols for Public Utilities adopted by the Wholesale Electric Quadrant (WEQ) of the North American Energy Standards Board (NAESB). The revisions made by NAESB in the WEQ Version 004 standards are designed to aid public utilities with the consistent and uniform implementation of requirements promulgated by the Commission as part of the pro forma Open Access Transmission Tariff (OATT).

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports that very high frequency (VHF) radio frequencies transfer between the active and standby windows of the tuning control panel (TCP) without flightcrew input. The uncommanded frequency changes could result in missed communications between the flightcrew and Air Traffic Control. This proposed AD would require updating the TCP operational software (OPS) and performing a software configuration check. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More💧West Virginia UIC Class VI Program Approved by EPA
The U.S. Environmental Protection Agency (EPA or the Agency) is approving an application from the State of West Virginia (the State) to revise the State's Safe Drinking Water Act (SDWA) section 1422 underground injection control (UIC) program to include Class VI injection well primary enforcement authority (primacy). This final rule allows the West Virginia Department of Environmental Protection (WVDEP) to issue UIC permits for geologic carbon sequestration facilities as Class VI wells and ensure compliance of Class VI wells under the UIC program. The EPA will remain the permitting authority for all well classes in Indian lands within the State and will also oversee West Virginia's administration of its UIC Class VI program as authorized under SDWA.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters. This proposed AD was prompted by reports of significant wear of the control rod assembly and pitch link assembly spherical bearings. This proposed AD would require measuring the radial play of certain control rod assembly and pitch link assembly spherical bearings, reporting the results, and depending on the results, taking corrective action. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. This proposed AD would also prohibit installing certain control rod assemblies and pitch link assemblies unless certain requirements are met. 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 Rolls-Royce Deutschland Ltd & Co KG Model Trent 1000-AE3, Trent 1000- CE3, Trent 1000-D3, Trent 1000-G3, Trent 1000-H3, Trent 1000-J3, Trent 1000-K3, Trent 1000-L3, Trent 1000-M3, Trent 1000-N3, Trent 1000-P3, Trent 1000-Q3, Trent 1000-R3, Trent 7000-72, and Trent 7000-72C engines. This AD was prompted by reports of cracked intermediate pressure compressor (IPC) shaft assembly front air seals. This AD requires an inspection of the affected IPC shaft assembly for cracking and, depending on the results of the inspection, repetitive inspections or replacement of the IPC shaft assembly front air seals, 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.
Learn More✈️New Airworthiness Directive for Austro Engine GmbH Engines
The FAA is superseding Airworthiness Directive (AD) 2023-20-03 for certain Austro Engine GmbH Model E4 and E4P engines. AD 2023-20-03 required repetitive engine oil analysis for aluminum content outside the acceptable limits and, if necessary, replacement of the pistons, piston rings, con-rods assembly, and crankcase or, as an alternative, replacement of the engine core. Since the FAA issued AD 2023-20-03, the manufacturer identified errors in the lists of affected engines and provided updated information, which prompted this AD. This AD retains the requirements of AD 2023-20-03, adds compliance times for additional affected engine serial numbers, and removes certain engine serial numbers from the applicability of the existing AD. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More🚁New Airworthiness Directive for Airbus Helicopters Compliance
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model AS350B2, AS350B3, and EC130B4 helicopters. This proposed AD was prompted by reports of broken cargo swing frames and the determination to change an existing repetitive inspection threshold. This proposed AD would require repetitively inspecting the cargo swing installation and frame and, depending on the results, corrective action, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More🚁FAA Proposes New Regulations for Safran Helicopter Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2B2 engines. This proposed AD was prompted by a manufacturer review of collected data from in-service engines that indicated the preference injector may clog over time caused by fuel coking, which decreases the permeability of the preference injector. This proposed AD would require initial and repetitive non-extinguishing tests for engine flameout and replacement of the preference injector if necessary, a one-time modification (software upgrade) of the electronic engine control unit (EECU) and, for certain engines, repetitive replacements of the preference injector, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️FAA's Proposed Airworthiness Directive for ATR72 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR72 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✈️FAA Proposes Airworthiness Directive for Pilatus Aircraft in 2025
The FAA proposes to supersede Airworthiness Directive (AD) 2023-26-05, which applies to certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. AD 2023-26-05 requires periodic replacement of affected titanium threaded bolts, a one-time inspection of the rudder mass balance arm and other elements of the rudder trim tab installation for correct attachment, damage (gouges), cracks, deformation, surface finish, and corrosion on any surrounding parts and, depending on findings, the accomplishment of applicable corrective actions. Since the FAA issued AD 2023-26-05, it was determined that some batches of titanium bolts had variations in the microstructure that could affect the fatigue characteristics. This proposed AD would require replacing affected short rudder-trim control rod assemblies with serviceable rudder-trim control rod assemblies having threaded steel bolts and would prohibit the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
