## Abstract

This action modifies Class E surface area airspace, and Class E airspace extending upward from 700 feet above the surface, at Perry Stokes Airport, Trinidad, CO. Airspace redesign is necessary to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at the airport due to the decommissioning of the Trinidad Non-Directional Radio Beacon (NDB) and cancellation of associated approaches. This action ensures the safety, efficiency, and management of Instrument Flight Rules (IFR) operations at the airport. Additionally, the airport's geographic coordinates are updated to match the FAA's aeronautical database.
