Read the full NTSB narrative

The accident aircraft departed the airport under power approximately 3 hours prior to the accident. Shortly after returning to the traffic pattern for landing, witnesses observed the aircraft enter a downwind for landing to the east. A witness reported that the pilot's downwind leg appeared normal, however, the base leg to final turn was close to the runway end resulting in a higher than normal glide path to final. Shortly after crossing the landing threshold, the glider pitched up, in conjunction with the speed brakes retracting, and the pilot initiated a turn to the right (south). The pilot rolled to a wings level attitude momentarily before entering a turn to the left. As the aircraft turned to the left, it pitched to a nose-low attitude and impacted terrain. The accident flight was the pilot's first solo landing approach to the accident airport.
