Amendment of Class E Airspace; Oscoda, MI

This action modifies Class E airspace at Oscoda-Wurtsmith Airport, Oscoda, MI. This action is required due to the decommissioning of the Au Sable VHF omnidirectional range (VOR) navigation aid, which provided navigation guidance for the instrument procedures at the airport, as part of the VOR Minimum Operational Network (MON) Program. Also, the geographic coordinates for the airport in the associated airspace are updated to coincide with the FAA' s aeronautical database. Airspace redesign is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
