## Abstract

This action modifies Area Navigation (RNAV) Route T-331 in the western United States. The modification is necessary due to the planned decommissioning of the Clovis, CA, VOR portion of the VOR/Tactical Air Navigation (VORTAC) navigation aid (NAVAID), which provides navigation guidance for portions of affected ATS route V-23. The decommissioning has rendered portions of V-23 unusable and amending T-331 helps overcome affected portions of V-23. The Clovis, CA, VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.
