Proposed Amendment of Class E Airspace, for Orange City, IA

This action proposes to modify Class E airspace extending up to 700 feet above the surface at Orange City Municipal Airport, Orange City, IA, to accommodate new standard instrument approach procedures (SIAPs) for instrument flight rules (IFR) operations at the airport. This action is necessary due to the decommissioning of the Orange City non directional radio beacon (NDB), and cancellation of the NDB approach, and would enhance the safety and management of IFR operations at the airport. The airport's coordinates also would be updated to match the FAA's aeronautical data base.
