Amendment to Class D Airspace; Jacksonville NAS Cecil Field, FL

This amendment modifies Class D airspace at Jacksonville NAS Cecil Field, FL, and will change the name of the airport to Cecil Field Airport. The U.S. Navy has discontinued operations at NAS Cecil Field, including decommissioning the Cecil Nondirectional Radio Beacon (NDB) and the Cecil Tactical Air Navigation (TACAN) navigational aids, thereby eliminating airspace extensions. The Jacksonville, FL, Port Authority has opened a contract airport traffic control tower at the airport. The control tower at Cecil Field is scheduled to be open 0800- 1800, daily, Monday through Friday. Therefore, the Class D airspace hours of operation will be amended from continuous to part time.
