✈️Proposed Airworthiness Directive for Airbus A350-941 and 1041 Aircraft
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by reports of deep spot faces on rib 9 at the lower flange bolting with the lower spar. This proposed AD would require a special detailed inspection for discrepancies of certain pylon bolts, and applicable corrective actions, 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 Environmental Protection Agency (EPA) is proposing approval of a State Implementation Plan (SIP) revision submitted by the Missouri Department of Natural Resources (MoDNR) on November 14, 2018. MoDNR requests that the EPA remove from its SIP two rules related to control of emissions of nitrogen oxides (NO<INF>X</INF>). One of the rules previously applied to electricity generating units (EGUs) and certain non-EGUs in a portion of the state and the other rule previously applied to EGUs throughout the entire state. The EPA has already approved a SIP revision that included provisions to sunset the two rules, and removal of the now-sunsetted rules from the SIP would not have an adverse effect on air quality. The EPA's proposed approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).
Learn More✈️Proposed Airworthiness Directive for Boeing 717-200 Aircraft
The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes. This proposed AD was prompted by a report of a nose landing gear-up landing caused by the failure of the upper lock link assembly. This proposed AD would require repetitive inspections for cracking of the upper lock link assembly and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️Proposed Airworthiness Directive for Boeing 767 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767-200, 767-300, 767-300F, and 767-400ER airplanes. This proposed AD was prompted by a heavy maintenance check that found corrosion damage on a Model 767 satellite communications (SATCOM) high gain antenna adapter plate. This proposed AD would require repetitive detailed inspections (DET) of the SATCOM high gain antenna adapter plate for corrosion and applicable on- condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️Proposed AD Impacting Airbus A350 Operations and Compliance
The FAA proposes to supersede Airworthiness Directive (AD) 2020-02-14, which applies to certain Airbus SAS Model A350-941 and - 1041 airplanes. AD 2020-02-14 requires a one-time inspection of the oxygen containers and adjacent panels and applicable corrective actions. Since the FAA issued AD 2020-02-14, it was determined that additional airplanes may be affected by the same unsafe condition. This proposed AD would continue to require the actions in AD 2020-02-14 and would require expanding the applicability to include additional airplanes, 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🌍Allegheny County Redesignation for Sulfur Dioxide Standards Approved
The Environmental Protection Agency (EPA) is approving both a redesignation request and state implementation plan (SIP) revision submitted on November 14, 2023 by the Commonwealth of Pennsylvania on behalf of the Allegheny County Health Department (ACHD). The request asked the EPA to redesignate the Allegheny County, Pennsylvania area from nonattainment to attainment for the 2010 1-hour primary sulfur dioxide (SO<INF>2</INF>) national ambient air quality standard (NAAQS), while the revision included Allegheny County's maintenance plan for the 2010 1-hour primary SO<INF>2</INF> standard for the Allegheny County Area. The EPA is approving this redesignation of the Allegheny County Area from nonattainment to attainment for the 2010 SO<INF>2</INF> NAAQS and the revision to the Pennsylvania SIP in accordance with the requirements of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the State Implementation Plan (SIP) and Operating Permits Program and the 112(l) plan submitted by the State of Kansas on February 20, 2023. The revised Kansas rules update the Class I emission fee and emissions inventory regulations, establish a Class II fee schedule and ensure that Kansas's Operating Permits Program is adequately funded. Approval of these revisions ensures consistency between the State and federally-approved rules and does not impact air quality.
Learn More🛩️FAA Issues New Airworthiness Directive for Bell Helicopters
The FAA is superseding Airworthiness Directive (AD) 2021-24- 09, which applied to certain Bell Textron Canada Limited Model 430 helicopters. AD 2021-24-09 required a visual inspection of the main rotor (M/R) pitch link clevis (clevis), rod end, and a certain part- numbered universal bearing, performing a purge grease, and performing a magnetic particle inspection of each M/R clevis, and depending on the inspection results, removing or replacing certain parts and performing additional actions. AD 2021-24-09 also required recurring inspections of each M/R clevis and each universal bearing. Since the FAA issued AD 2021-24-09, the manufacturer has reduced the life limits of the affected parts and introduced new M/R pitch link assemblies by re- identifying the M/R pitch link assemblies that were required to be inspected by AD 2021-24-09. This AD requires similar actions as AD 2021-24-09 but reduces the life limits and requires replacing the M/R pitch link assemblies with re-identified part numbered assemblies. These actions are 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🚁New Airworthiness Directive for Bell Textron Helicopters
The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited (BTCL) Model 505 helicopters. This AD was prompted by reports of possible chafing in certain locations between the basic and supplemental helicopter wiring and the structure. This AD requires repetitively inspecting the wire harnesses at certain locations for damage, and if any wire damage is found, repairing the damaged wire/bundles, 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 Airworthiness Directive for Airbus Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC135T3, EC635T2+, MBB- BK 117 C-2, MBB-BK 117 D-2, and MBB-BK 117 D-3 helicopters. This proposed AD was prompted by a review of design data and the determination for recalculation of accumulated hoist boom cycles (cycles) and repetitive inspections. This proposed AD would require determining the total cycles of certain hoist boom assemblies, inspecting those hoist boom assemblies, and depending on the results, taking corrective action. This proposed AD would also prohibit installing those hoist boom assemblies unless certain requirements are met. These actions are 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.
