🚁FAA Airworthiness Directive for Airbus Helicopters Safety Compliance

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 D-3 helicopters. This AD was prompted by a report of over-torqued swashplate bolts on helicopters in service and in production. This AD requires removal of certain swashplate bolts from service and replacement with new (never previously installed on a helicopter) bolts, a one-time inspection for damage on the threads of the bearing ring and control ring of the swashplate and, depending on the results of the inspection, corrective actions. This AD also prohibits the installation of certain swashplates on any helicopter unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.

✈️Revocation of Airway Routes in Alaska

This action revokes Colored Federal Airway Green 6 (G-6) and Alaskan Very High Frequency Omnidirectional Range (VOR) Federal Airways V-459 and V-496 in Alaska. The identifier V-459 is also used for a VOR Federal Airway in California. This action revokes the Alaskan V-459, not the V-459 in California. The FAA is taking this action due to the pending decommissioning of the St. Marys, AK, Nondirectional Radio Beacon (NDB) and the Aniak, AK, NDB.

✈️Proposed Airworthiness Directive for Goodrich Cabin Attendant Seats

The FAA proposes to adopt a new airworthiness directive (AD) for Goodrich cabin attendant seats installed on Airbus SAS Model A330- 200 series, A330-200 Freighter series, A330-300 series, A330-841, A330- 941, A340-200 series, A340-300 series, A340-541, and A340-642 airplanes. This proposed AD was prompted by a report that track attachments used on certain part-numbered seats are non-compliant. This proposed AD would require replacing all seat track attachments and hardware and re-identifying the seat with a new part number. The FAA is proposing this AD to address the unsafe condition on these products.

🌬️Mojave Desert Air Quality Regulation and Its Business Implications

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Mojave Desert Air Quality Management District (MDAQMD or "the District") portion of the California State Implementation Plan (SIP). These revisions concern definitions that are necessary to implement and enforce local rules that regulate air pollution. We are proposing to approve a definitions rule under the Clean Air Act (CAA or the "Act"). We are also proposing to approve the rescission of earlier versions of this rule from the California SIP as they are no longer needed to under the CAA. We are taking comments on this proposal and plan to follow with a final action.

🌿EPA Approves Missouri SIP Revisions for Petroleum Emission Controls

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the State Implementation Plan (SIP) for the State of Missouri related to the control of emissions during petroleum liquid storage, loading and transfer in the Kansas City metropolitan area. The revisions include adding incorporations by reference to other state rules, adding definitions specific to the rule, revising unnecessarily restrictive or duplicative language, and making administrative wording changes. These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's final approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).
