The U.S. Environmental Protection Agency (EPA or Agency) has received a complete Underground Injection Control (UIC) primacy application from the State of Arizona requesting primary enforcement responsibility (primacy) for Class I-VI injection wells under the Safe Drinking Water Act (SDWA) section 1422. The EPA's approval of the State's UIC program primacy application would allow the Arizona Department of Environmental Quality (ADEQ) to authorize underground injection for all underground injection wells regulated under the Federal SDWA and ensure compliance with UIC program requirements. The EPA proposes to issue a final rule approving Arizona's application to implement the UIC program for Class I-VI injection wells located within the State, except those on Indian lands. The EPA proposes amendments to reflect this proposed approval of Arizona's UIC program primacy application.
Learn More✈️Proposed Airworthiness Directive for Gulfstream Aerospace Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model GVI airplanes. This proposed AD was prompted by a determination that new and more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new and more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.

This action amends Very High Frequency Omnidirectional Range (VOR) Federal Airways V-161, V-163, and V-568; and establishes United States Area Navigation (RNAV) Route T-545. The FAA is taking this action due to the planned decommissioning of the VOR portion of the Three Rivers, TX (THX), VOR/Tactical Air Navigation (VORTAC) navigational aid (NAVAID). The Three Rivers VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 2000EX airplanes. This proposed AD was prompted by reports of the incorrect installation of the very high frequency omnidirectional range and localizer (VOR/LOC) antenna coupler. This proposed AD would require implementing an operational limitation for Category (CAT) II and CAT III approaches, inspecting the VOR/LOC antenna coupler, and reinstalling the VOR/LOC antenna coupler if necessary, 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 is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by reports of water leakage from the potable water system due to improperly installed waterline couplings, and water leaking into the electronics equipment (EE) bays from above the floor in the main cabin, resulting in water on the equipment in the EE bays. This AD requires an inspection of seat tracks above the EE bays for missing, damaged, or deteriorated sealant, moisture barrier tape, or tape dams, as applicable, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️New Airworthiness Directive for Airbus Canada's BD-500 Airplanes
The FAA is superseding Airworthiness Directive (AD) 2022-19- 09, which applied to all Airbus Canada Limited Partnership Model BD- 500-1A10 and BD-500-1A11 airplanes. AD 2022-19-09 required repetitive inspections of the left and right main landing gear (MLG) lower spindle pins to detect corrosion and applicable repair or replacement. This AD was prompted by reports of in-service findings of corrosion on the flange of the MLG lower spindle pin. This AD continues to require certain actions in AD 2022-19-09. This AD also requires changing the tracking of flight cycles for inspections from the usage of the MLG to the usage of MLG lower spindle assemblies and replacement of affected MLG lower spindle assemblies, removes airplanes from the applicability, and prohibits the installation of affected parts under certain conditions; as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️Proposed AD on Boeing 787 Requires Inspections and Replacements
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-9 and 787-10 airplanes. This proposed AD was prompted by reports of multiple supplier notices of escapement (NOEs) documenting pressure deck splice fittings that were possibly manufactured with an incorrect titanium alloy material. This proposed AD would require an inspection of the attach fittings and upper splice fitting of the stub beam horizontal pressure deck (HPD) to determine the type of titanium alloy material, and applicable on- condition actions. 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 MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 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 reports that the cockpit voice recorder (CVR) impact switch was installed in the wrong direction. This AD requires an inspection of the CVR impact switch installation to confirm that the reset switch faces forward, and applicable on-condition actions, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
