Amendment of Class E Airspace; Mount Vernon, IL

This action modifies the Class E surface area and Class E airspace extending upward from 700 feet above the surface at Mount Vernon Airport, Mount Vernon, IL. This action is due to an airspace review caused by the decommissioning of the Mount Vernon VHF omnidirectional range (VOR), which provided navigation information to the instrument procedures at this airport, as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates and name of the airport are also being updated to coincide with the FAA's aeronautical database. Airspace redesign is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
