The student pilot, who had logged at least 93 hours of flight time in the accident aircraft (total time), was engaged in livestock spotting at low altitude (200 feet above ground) in turbulent conditions with a wind out of the northwest estimated at 20 knots. During a 40-degree angle of bank, right 180 degree turn, the aircraft's angle of bank exceeded 90 degrees and the pilot applied full left aileron and rudder with no effect. The aircraft continued a rolling right descent and when about 80-90 feet above ground, the roll reversed into a left roll during which the left wingtip and nose impacted the ground. The aircraft cartwheeled counter-clockwise 270 degrees to a stop during which the engine separated from the airframe. A post-crash fire consumed the aircraft.
Probable Cause: The student pilot's failure to maintain adequate flying airspeed in a turn while maneuvering close to the ground resulting in a stall condition. A contributing factor was the turbulent wind conditions.
