Amendment of Class E Airspace for the Following Michigan Towns; Alma, MI; Bellaire, MI; Cadillac, MI; Drummond Island, MI; Gladwin, MI; Holland, MI; and Three Rivers, MI

This action modifies Class E airspace extending upward from 700 feet above the surface at Gratiot Community Airport, Alma, MI; Antrim County Airport, Bellaire, MI; Wexford County Airport, Cadillac, MI; Drummond Island Airport, Drummond Island, MI; Charles C. Zettel Memorial Airport, Gladwin, MI; Park Township Airport and West Michigan Regional Airport, Holland, MI; and Three Rivers Municipal Dr. Haines Airport, Three Rivers, MI. Decommissioning of non-directional radio beacons (NDB), cancellation of NDB approaches, or implementation of area navigation (RNAV) procedures have made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the above airports. This action also updates the geographic coordinates of Three Rivers Municipal Dr. Haines Airport, and the name change of West Michigan Regional Airport (formerly Tulip City Airport) to coincide with the FAA's aeronautical database.
