Proposed Amendment of Class D and Class E Airspace; Fort Knox, KY, and Louisville, KY

This action proposes to amend Class E airspace designated as an extension to Class D airspace by removing the Notice to Airmen (NOTAM) part-time status at Godman Army Airfield (AAF) Fort Knox, KY; and Bowman Field Airport, Louisville, KY. This action would also update the geographic coordinates of these airports in the associated Class D and E airspace descriptions. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at these airports.
