## Abstract

This action modifies Class E airspace areas at Casper, Natrona County International Airport, Casper, WY, to facilitate vectoring of Instrument Flight Rules (IFR) traffic from en route airspace to the airport. Decommissioning of the Muddy Mountain VOR Omnidirectional Range Tactical Air Navigation (VORTAC) has made reconfiguration necessary for the safety and management of aircraft operations at the airport.
