Amendment of Class D and E Airspace; Casper, WY

This action amends Class D airspace, and Class E airspace extending upward from 700 feet or more above the surface, and removes Class E airspace designated as an extension, at Casper/Natrona County International Airport, Casper WY. After a biennial review, the FAA finds this action necessary to accommodate airspace redesign for the safety and management of instrument flight rules (IFR) operations within the National Airspace System. Also, this action updates the airport's name and geographic coordinates for the associated Class D and E airspace areas to reflect the FAA's current aeronautical database.
