Amendment of Class E Airspace; Oskaloosa, IA

This action modifies Class E airspace extending upward from 700 feet above the surface at Oskaloosa Municipal Airport, Oskaloosa, IA, to accommodate new standard instrument approach procedures for instrument flight rules (IFR) operations at the airport. This action is necessary due to the decommissioning of the Oskaloosa non directional radio beacon (NDB), and cancellation of the NDB approach procedure, and enhances the safety and management of IFR operations at the airport.
