Accident Details
The pilot reported that during the landing approach to the runway 12 ramp area, he entered the downwind leg of the airport traffic pattern at an altitude of 1,000 feet above the ground. According to the pilot, downdrafts caused the glider to rapidly lose altitude, making it impossible to reach the intended landing area. The pilot subsequently performed a landing in a field located northwest of the airport. During the landing, the glider's left wing struck a mesquite bush, and the aircraft ground looped.
Aircraft Damage
The glider sustained substantial damage to the fuselage, canopy, and left wing.
Weather Conditions
A weather reporting station situated five miles south of the accident site reported winds from 140 degrees at 17 knots, gusting to 24 knots, prior to the accident. A review of local weather data indicated that there were no strong lifting mechanisms for the formation of clouds or precipitation near the surface at the time of the accident. The pilot likely encountered gusty surface winds while descending to the airport.
Additional Information
The pilot reported no preimpact mechanical failures or malfunctions with the glider that would have precluded normal operation. Runway 12 is 8,810 feet long and 150 feet wide. The ramp area, which parallels the runway to the north, is 7,500 feet long and 350 feet wide.
