Amendment to Class E Airspace; Winfield/Arkansas City, KS

This action amends Class E airspace area at Strother Field, Winfield/Arkansas City, KS. A review of the Class E airspace area for Strother Field, KS indicates it does not comply with the criteria for 700 feet Above Ground Level (AGL) airspace required for diverse departures as specified in FAA Order 7400.2D. The Class E airspace has been enlarged to conform to the criteria of FAA Order 7400.2D. The review also indicates the extension to the south can be eliminated. The intended effect of this rule is to provide additional controlled Class E airspace for aircraft operating under Instrument Flight Rules (IFR), eliminate the extension, and comply with the criteria of FA Order 7400.2D.
