## Abstract

This action amends the Class E airspace extending upward from 700 feet above the surface at Harrison County Airport, Cadiz, OH; Noble County Airport, Caldwell, OH; and Cambridge Municipal Airport, Cambridge, OH. These actions are the result of airspace reviews caused by the decommissioning of the Newcomerstown VHF omnidirectional range (VOR) navigation aid, which provided navigation information for the instrument procedures at these airports, as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates of Harrison County Airport and Noble County 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 these airports.
