## Abstract

This action modifies the Class E airspace area at Willows-Glen County Airport, CA. The establishment of a Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) to Runway (RWY) 34 at Willows-Glen County Airport has made this action necessary. Additional controlled airspace extending upward from 700 feet or more above the surface of the earth is needed to contain aircraft executing the GPS RWY 34 SIAP to Willows-Glen County Airport. The intended effect of this action is to provide adequate controlled airspace for Instrument Flight Rules (IFR) operations at Willows-Glen County Airport, Willows, CA.
