## Abstract

This action amends Class E airspace area at Denison Municipal Airport, Denison, IA. A review of the Class E airspace for Denison Municipal Airport 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 area is enlarged to conform to the criteria of FAA Order 7400.2D. In addition, a minor revision to the geographic coordinates for the Denison Nondirectional Radio Beacon (NDB) is included in this document. The intended effect of this rule is to provide additional controlled Class E airspace for aircraft operating under Instrument Flight Rules (IFR), comply with the criteria of FAA Order 7400.2D, and amend the geographic coordinates for the Denison NDB.
