Amendment of Class E Airspace; Mapleton, IA
This action modifies Class E airspace extending upward from 700 feet above the surface at James G. Whiting Memorial Field Airport, Mapleton, IA. Decommissioning of the Mapleton non-directional radio beacon (NDB), cancellation of NDB approaches, and implementation of area navigation (RNAV) procedures have made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport.
