Executive Summary:About 1026, on February 6, 1980, a Cessna TU-206G, N7393N, and a United States Air Force tactical aircraft, a General Dynamics F-111D, collided in midair about 11 nmi northeast of Cannon Air Force Base. The Cessna had departed Alemeda Airport, Albuquerque, New Mexico, had made an en route stop at Tucumcari, New Mexico, and was destined for Clovis, New Mexico. On the morning of February 6, the General Dynamics F-111D had departed Cannon Air Force Base, located about 13 miles southwest of the Clovis Municipal Airport, on a cross country training flight. The F-111D was returning to Cannon Air Force Base to complete the mission. The two aircraft collided near 5,800 feet m.s.1. The pilot and passenger aboard the Cessna and both crewmembers of the F-111D were killed. The weather was clear and the visibility was reported as 30 miles.

The National Transportation Safety Board determines that the probable cause of this accident was the failure of both aircraft to request radar traffic advisories, the failure of the F-111D flightcrew to see and avoid the Cessna TU-206G, and the failure of the RAPCON controllers to observe the Cessna radar target and to issue traffic advisories to the F-111D. Contributing to the accident were the limitations of the see and avoid concept in a terminal area with low speedfhigh speed traffic.
