NTSB narrative
Witnesses saw the glider heading south about 8 to 10 feet above the runway surface, at a fast rate of speed, spoilers not deployed, and intending to land. The witnesses observed the glider flare several feet above the runway, pull up at a high angle of attack, and high rate of speed. Before coming to rest the glider began a "wheelbarrow" effect with several pull-ups and descents several times, nosed down at about 30 degree angle, and impact the runway surface very hard. An examination of the dive brakes after the accident did not reveal any discrepancies. The pilot was given an NTSB Pilot/Operator Accident Report Form 6120.1/2 by the FAA inspector, but a completed form was not received by the NTSB.
Probable cause
the pilot's failure to extend the dive brakes during approach and his excessive airspeed and improper landing flare which resulted in the airplane nosing down and impacting with the runway.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
