NTSB narrative
At the conclusion of a cross-country flight, the glider pilot arrived at his intended destination and entered a normal left-hand traffic pattern to runway 23R. The pilot reported that he observed the wind conditions on the downwind and base legs, and he maintained a normal traffic pattern. The wind was from 190 degrees at 10 knots. The initial approach to the runway was normal. However, the pilot said that on short final approach he suddenly encountered a "very heavy downward sink, accompanied by a sharp drop in IAS [indicated air speed]." The pilot responded by retracting the wing spoilers and adjusting the glider's pitch to maintain the requisite approach speed. The downdraft continued, and despite the performance capabilities of his glider the pilot was unable to glide to the runway. The pilot turned to avoid a set of power lines, and a wing contacted the ground. The glider touched down hard on the flat open terrain several hundred yards short of the threshold.
Probable cause
The pilot's misjudged distance and altitude while on final approach to land. A factor contributing to the accident was a downdraft.

- 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.
