## Abstract

This action amends the Class E airspace extending upward from 700 feet above the surface at multiple Minnesota Towns and revokes the Class E airspace extending upward from 700 feet above the surface at Silver Bay Municipal Airport, Silver Bay, MN. This action is the result of airspace reviews caused by the decommissioning of multiple non- federal non-directional beacons (NDBs) within Minnesota. The names and geographic coordinates of various airports are also being updated to coincide with the FAA's aeronautical database.
