Amendment of Class E Airspace; Marshall Army Airfield, Fort Riley, KS

The control tower at Marshall Army Airfield, Ft. Riley, KS, has been closed and will not be operational in the foreseeable future. With the closure of the control tower, the Class D surface area has been removed. This action removes the Class E surface area extension and establishes a new Class E surface area at Marshall Army Airfield, Ft. Riley, KS. The new Class E surface area provides controlled airspace to accommodate Instrument Flight Rules (IFR) operations. The intended effect of this action is to contain IFR operations within controlled airspace and to facilitate separation of aircraft operating under instrument flight rules.
