Amendment of Class D Airspace and Class E Airspace; Aberdeen, MD

This amends Class D airspace, Class E airspace designated as an extension to a Class D surface area, and Class E airspace area extending upward from 700 feet or more above the surface at Phillips Army Air Field (AAF), Aberdeen, MD. This action accommodates airspace reconfiguration due to the decommissioning of Aberdeen non-directional radio beacon (NDB), and cancellation of the NDB approaches. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport. This action also updates the geographic coordinates of the airport, and replaces the outdated term Airport/Facility Directory with the term Chart Supplement in the legal descriptions of associated Class D and E airspace.
