## Abstract

This action amends the Class E airspace extending upward from 700 feet above the surface at Trenton Municipal Airport, Trenton, MO. This action is the result of an airspace review caused by the decommissioning of the Trenton non-directional beacon (NDB) navigation information to the instrument procedures at this airport. The geographic coordinates of the airport are also being updated to coincide with the FAA's aeronautical database. Airspace redesign is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
