✈️Airworthiness Directive for BRP-Rotax Engines
The FAA is adopting a new airworthiness directive (AD) for certain BRP-Rotax GmbH & Co KG (Rotax) Model 912 iSc2 Sport, 912 iSc3 Sport, 915 iSc2 C24, and 915 iSc3 C24 engines. This AD was prompted by a report of deviations during the manufacturing process that caused incorrect application of a certain thread-locker to certain sprag clutch housing and oil spray nozzles. This AD requires repetitive operational checks of the battery backup function with removal of the engine from service if insufficient battery power is found, one-time inspections of the oil spray nozzle and generator stator assembly, and, depending on the results of the inspections, replacement with parts eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.

The Environmental Protection Agency (EPA) is finalizing multiple actions related to the Washington, DC-MD-VA nonattainment area (the Washington Area or the Area) for the 2015 8-hour ozone national ambient air quality standards (2015 ozone NAAQS). First, the EPA is determining that the Washington Area attained the 2015 ozone NAAQS by the applicable attainment date of August 3, 2024. Second, the EPA is determining that the Washington Area has clean data under the EPA's Clean Data Policy. Lastly, the EPA is taking final action on an exceptional events request submitted by the District of Columbia (DC) on March 20, 2024, and concurred on by the EPA on July 17, 2024. This action addresses the EPA's obligation under Clean Air Act (CAA) sections 179(c) and 181(b)(2) to determine whether the Washington Area attained the 2015 ozone NAAQS by the August 3, 2024 attainment date and, as set forth in the EPA's Clean Data Policy, will suspend the obligation of DC, the State of Maryland (MD), and the Commonwealth of Virginia (VA) to submit certain attainment planning requirements for as long as the Washington Area continues to attain the 2015 ozone NAAQS. This action is being taken under the CAA.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters (Airbus) Model AS350B, AS350B1, AS350B2, AS350B3, AS350BA, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, AS355NP, EC130B4, and EC130T2 helicopters. This AD was prompted by a manufacturer assessment that determined additional actions are necessary to improve particle detection for main gearboxes (MGBs) with certain planet gear bearings installed. This AD requires repetitively inspecting the MGB bevel wheel and the MGB magnetic plug for particles and prohibits installing an affected MGB unless certain requirements are met. These actions are 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.

This action proposes to remove Class D and E4 airspace at Phillips Army Airfield (AAF) due to the closure of the air traffic control tower. This action proposes to establish Class E2 airspace extending upward from the surface above Phillips AAF, Aberdeen, MD, at the request of the United States Army to provide the required airspace for Instrument Flight Rules (IFR) operations at Phillips AAF. This action also proposes to amend Class E5 airspace to accommodate the decommissioning of Aberdeen non-directional radio beacon (NDB), and cancellation of the associated instrument approach procedures. Controlled airspace is necessary for the safety and management of IFR operations in the area for existing instrument approaches.
Learn More✈️Regulatory Amendments to Standard Instrument Approach Procedures
This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
