Amendment of Class D and Class E Airspace, Revocation of Class E Airspace; Chico, CA

This action modifies Class D airspace, Class E airspace extending upward from 700 feet above the surface, and removes Class E surface area airspace designated as an extension at Chico Municipal Airport, Chico, CA. The FAA found it necessary to amend the airspace area by increasing the Class E airspace extending upward from 700 feet above the surface for the safety and management of Instrument Flight Rules (IFR) operations for arriving and departing aircraft at the airport. The FAA found no standard instrument approach procedures requiring Class E surface area airspace designated as an extension to Class D airspace. This action changes from navigation aids to geographic coordinate references in the legal description and updates the geographic coordinates of Chico Municipal and Ranchaero Airports for the Class D and E airspace areas noted above.
