NTSB summary

HISTORY OF FLIGHT On June 27, 2005, approximately 1225 mountain daylight time, an unregistered CGS Aviation Hawk Two Place Arrow experimental light-sport airplane was destroyed when it impacted terrain following an uncontrolled descent during the base leg of the visual approach to runway 19 at Jackson Hole Airport (JAC), Jackson, Wyoming. The commercial pilot, who was the sole occupant and owner of the airplane, sustained fatal injuries. Visual meteorological conditions prevailed, and a flight plan was not filed for the Title 14 Code of Federal Regulations (CFR) Part 91 personal flight. The local flight departed JAC at 1218. Several witnesses at JAC reported that the airplane departed runway 19, and immediately climbed to approximately 500 feet above ground level (agl), while maintaining runway heading. The airplane then turned left onto the crosswind leg of the traffic pattern and maintained a slight climb. Two witnesses, who were traveling southbound in motor vehicles on Highway 89 (parallel to JAC runway 01/19), reported that they observed the airplane on the left downwind leg at an altitude of 700 to 900 feet agl. One witness, who was also in a vehicle, observed the airplane in "normal flight" at an altitude of 800 to 1,000 feet flying parallel to the east of Highway 89. The witness observed the airplane turn left (west) onto the base leg for runway 19 "in normal flight and was descending but not what appeared to be abnormal." The airplane continued a nose-low descent toward the terrain. Approximately 200 feet agl, the airplane began a "steeper" nose-low descent toward

Probable cause

The loss of airplane pitch control resulting from the pilot/owner's improper reinstallation of the rear locking collar on the elevator control torque tube, which allowed the torque tube to move rearward during flight and loosen the elevator control cable tension.
