## Abstract

This action will modify Class E airspace at Lake Havasu, AZ. Additional controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at Lake Havasu City Airport, Lake Havasu, AZ. This will improve the safety of Instrument Flight Rules (IFR) aircraft executing the new RNAV GPS SIAP at Lake Havasu City Airport, Lake Havasu, AZ. This also makes a minor change in the airport description. It changes the 2.2-mile radius of Chemehuevi Valley Airport to a 2.3-mile radius.
