## Abstract

This action amends the Class D and Class E airspace and revokes Class E airspace at Fort Knox, KY. This action is the result of a biennial airspace review conducted due to the decommissioning of the Godman non-directional beacon (NDB). The geographic coordinates of Godman AAF (Army Air Field), Fort Knox, KY, are also being updated to coincide with the FAA's aeronautical database. This action brings the airspace into compliance with FAA orders and supports instrument flight rule (IFR) procedures and operations.
