Proposed Amendment of Class D and E Airspace; Casper, WY

This action proposes to amend controlled airspace at Casper/ Natrona County International Airport, Casper WY. After a biennial review, the FAA proposes to enlarge Class D airspace; remove Class E airspace designated as an extension, reduce Class E airspace extending upward from 700 feet above the surface, and remove Class E airspace extending upward from 1,200 feet above the surface. Also, this action would update the airport's name and geographic coordinates for the associated Class D and E airspace areas to reflect the FAA's current aeronautical database. These proposed changes would enhance safety and management of instrument flight rules (IFR) operations at the airport.
