What the agency says
This action removes Class D and E4 airspace at Phillips Army Airfield (AAF), Aberdeen, MD, due to the closure of the air traffic control tower. This action establishes Class E2 airspace extending upward from the surface above Phillips AAF at the request of the United States Army to provide the required airspace for Instrument Flight Rules (IFR) operations at Phillips AAF. This action also amends Class E5 airspace to accommodate the decommissioning of the Aberdeen non-directional radio beacon (NDB) and cancellation of the associated instrument approach procedures. Controlled airspace is necessary for the safety and management of IFR operations in the area for existing instrument approaches.
