This action proposes performance-based regulations to enable the design and operation of unmanned aircraft systems (UAS) at low altitudes beyond visual line of sight (BVLOS) and for third-party services, including UAS Traffic Management (UTM), that support these operations. The FAA Reauthorization Act of 2024 directs the development of this proposed rule. This proposed rule is necessary to support the integration of UAS into the national airspace system (NAS). This proposed rule is intended to provide a predictable and clear pathway for safe, routine, and scalable UAS operations that include package delivery, agriculture, aerial surveying, civic interest, operations training, demonstration, recreation, and flight testing. TSA proposes to make complementary changes to its regulations to ensure it can continue to impose security measures on these operations under its current regulatory structure for civil aviation.
The FAA proposes to supersede Airworthiness Directive (AD) 2024-21-02, which applies to Lycoming Engines (Lycoming) model engines that have certain connecting rod assemblies installed. AD 2024-21-02 requires repetitive oil inspections for bronze metal particulates and, if found, additional inspections of the connecting rod bushings for damage, proper fit, movement, and wear, and replacement if necessary. As terminating action to the connecting rod bushing inspections, AD 2024-21-02 also requires replacement of the connecting rod bushings with parts eligible for installation. Since the FAA issued AD 2024-21- 02, the ship date range for potentially affected parts that may be subject to connecting rod failure has been expanded, and additional parts that are eligible for installation have been identified. This proposed AD would require the actions in AD 2024-21-02 and would require expanding the applicability. The FAA is proposing this AD to address the unsafe condition on these products.
This action proposes special conditions for the Pratt and Whitney Canada (PWC) aircraft engine model PW220A. This engine will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for engines.
