✈️Proposed Airworthiness Directive for Airbus Canada Models BD-500-1A10/1A11
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by the discovery that titanium fasteners had been incorrectly installed in the butt strap at the outer wing box lower skin to center wing box interface in lieu of the correct nickel alloy fasteners. This proposed AD would require the identification of fasteners installed in the butt strap at the outer wing box lower skin to center wing box interface, and applicable on- condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2022-19-13, which applies to all Airbus Helicopters Model AS355E, AS355-F, AS355-F1, AS355F2, AS355N, and AS355NP helicopters. AD 2022- 19-13 requires incorporating into existing maintenance records certain requirements (airworthiness limitations). Since the FAA issued AD 2022- 19-13, a determination was made that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the airworthiness limitations section (ALS) of the existing maintenance manual (MM) or instructions for continued airworthiness (ICAs) and the existing approved maintenance or inspection program, as applicable. 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 Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211 Trent 768-60, 772-60, and 772B-60 engines. This proposed AD was prompted by a report that a batch of low pressure (LP) compressor blades are more prone to cracking due to a deviation from the approved blade configuration design. This proposed AD would require removal from service of the affected LP compressor blades and replacement with a serviceable part. 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 Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-3 helicopters. This proposed AD was prompted by a report of excessive vibrations in-flight due to an incorrect installation of the angular ball bearing of the control ring assembly. This proposed AD would require a one-time inspection of the affected swashplates and, depending on the results of the inspection, corrective actions. This AD would prohibit the installation of an affected swashplate on a helicopter, unless certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2023-25- 09, which applied to all Airbus SAS Model A318, A319, A320, A321, A330- 200, A330-200 Freighter, A330-300, A330-800, A330-900, A340-200, A340- 300, A340-500, and A340-600 series airplanes. AD 2023-25-09 required replacing SafeLav gaseous oxygen containers (SLGOCs) affected by a production deficiency and prohibiting the installation of affected SLGOCs. Since the FAA issued AD 2023-05-09, a new airplane model has been certified, on which affected parts could be installed in service. This AD continues to require the actions in AD 2023-25-09 and adds airplanes to the applicability. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by reports of certain fuel transfer float valves failing in the closed position, preventing normal fuel transfer between the center and wing fuel tanks. This proposed AD would require replacing the existing fuel transfer float valves on airplanes that are approved for extended-range twin-engine operation performance standards (ETOPS). The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2024-19-14, which applies to certain The Boeing Company Model 777-200, 777-200LR, 777-300, 777-300ER, and 777F series airplanes. AD 2024-19-14 requires repetitive inspections and bond resistance measurement of the bonding jumpers on the first fuel feed tube installed immediately forward of the wing front spar at the left and right main fuel tank penetrations, and applicable corrective actions. Since the FAA issued AD 2024-19-14, the FAA determined that additional inspections are required to address the unsafe condition. This proposed AD would require repetitive detailed inspections (DET), repetitive bond resistance measurement, and applicable on-condition actions. This proposed AD would also expand the applicability and require revising the existing maintenance or inspection program, as applicable, to incorporate a certain airworthiness limitation. 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 certain Airbus SAS Model A318-111, -112, and -122; A319-111, -112, -113, -114, -115, -131, -132, and -133; A320-211, -212, -214, -216, - 232, -233, -251N, -252N, -253N, -271N, -272N, and -273N; and A321-211, -212, -213, -231, -232, -251N, -252N, -253N, -271N, -272N, -251NX, - 252NX, -253NX, -271NX, -272NX airplanes. This proposed AD was prompted by the detection of a deviation from the manufacturing process during a review of the cold working process in the assembly line. This proposed AD would require repetitive special detailed inspections (SDIs) and rototest or high frequency eddy current (HFEC) and rototest inspections of the affected fasteners and fastener holes, and applicable on- condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

The U.S. Environmental Protection Agency (EPA) is approving an application from the State of Arizona (the State) that requests 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 will allow the Arizona Department of Environmental Quality (ADEQ) to authorize underground injection for all underground injection wells regulated under the SDWA within the State's jurisdiction and ensure compliance with UIC program requirements. The EPA will remain the permitting authority for all well classes on Indian lands within the State, except for Class II wells on Navajo Indian lands for which the EPA has granted the Navajo Nation primacy for the SDWA Class II UIC program.
