Accident Overview
A glider pilot concluded a cross-country flight by entering a normal left-hand traffic pattern for runway 23R at the intended destination. The pilot observed wind conditions on the downwind and base legs, reporting the wind from 190 degrees at 10 knots. The initial approach to the runway proceeded normally.
Encounter with Downdraft
On short final approach, the pilot unexpectedly encountered a "very heavy downward sink, accompanied by a sharp drop in IAS [indicated air speed]." In response, the pilot retracted the wing spoilers and adjusted the glider's pitch to maintain the requisite approach speed. However, the downdraft continued, and despite the glider's performance capabilities, the pilot was unable to glide to the runway.
Evasive Maneuver and Landing
The pilot turned to avoid a set of power lines, and during the maneuver, a wing contacted the ground. The glider touched down hard on flat open terrain several hundred yards short of the runway threshold. As the glider came to a stop, the fuselage severed in front of the vertical fin, the horizontal stabilizer broke in half, and the fuselage was deformed.
Subsequent Actions
The pilot's report details the wind conditions, the sudden downdraft, and the corrective actions taken. The aircraft sustained substantial damage. No further information regarding occupants or injuries is provided in the source.
