## Abstract

This action amends the Class E airspace area at Mason City Municipal Airport, Mason City, IA. The FAA has developed an Instrument Landing System (ILS) Runway (RWY) 35 Standard Instrument Approach Procedure (SIAP) to serve the Mason City Municipal Airport. The enlarged Class E airspace area 700 feet Above Ground Level (AGL) will contain the ILS RWY 35 SIAP in controlled airspace. The intended effect of this rule is to provide additional controlled Class E airspace extending upward from 700 feet AGL to accommodate this SIAP.
