## Abstract

This action amends Class E airspace extending upward from 700 feet or more above the surface at Cambridge-Dorchester Regional Airport, Cambridge, MD, to accommodate airspace reconfiguration due to the decommissioning of the Cambridge non-directional radio beacon and cancellation of the NDB approach. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport. This action also corrects the region identifier in the description header, and updates the airport name and geographic coordinates.
