Federal Aviation Administration June 21, 2024 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-401 and -402 airplanes. This proposed AD was prompted by a report of an in- flight event where isolation valve caution messages were received. This proposed AD would require inspecting the fuse/shuttle valve serial numbers, and replacing certain fuse/shuttle valves, as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

This action amends the Class E airspace at Covington, KY. This action is the result of an airspace review conducted due to the decommissioning of the Cincinnati very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operating Network (MON) Program. The name and geographic coordinates of various airports are also being updated to coincide with the FAA's aeronautical database. This action brings the airspace into compliance with FAA orders to support instrument flight rule (IFR) operations.

This action amends Jet Route J-220 by removing an unnecessary mid-point from the route description. This action is an administrative change and does not affect the airspace boundaries or operating requirements.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) 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 safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
