On March 8, 1993, at approximately 1530 mountain standard time, during the landing roll at Double Eagle II Airport, Albuquerque, New Mexico, a Cessna 180J, N7770K, was substantially damaged following a loss of control. The private pilot did not sustain injuries. Visual meteorological conditions prevailed for the personal flight. The Federal Aviation Administration (FAA) inspector examined the accident site. Flight control continuity was confirmed. Damage involved the left wing and left elevator. During an interview with the pilot by the FAA inspector, the pilot stated the facts in this paragraph. The tailwheel developed a "severe vibration" during a landing at the Coronado Airport, Albuquerque, New Mexico, earlier that day. The pilot and a mechanic tightened the tailwheel nut. During the landing roll at the Double Eagle II Airport, the tailwheel "vibration occurred and the airplane veered to the right of the runway and ground looped."
