NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

During the takeoff roll, the glider encountered a strong gust of wind from behind the aircraft, which caused it to veer to the left. The pilot was able to release from the tow plane, but was unable to lift the left wing to an adequate height before it collided with a runway distance remaining sign. Although the pilot contended that the sign had been an obstruction from the time the airport crew had moved it from behind the takeoff area to in front of the takeoff area, the distance of the sign from the runway was consistent with parameters outlined in a Federal Aviation Administration Advisory Circular (AC) on the placement of runway distance remaining signs. At the time of the accident the wind was variable at 10 knots with gusts to 15 knots.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain control of the glider while taking off with a gusting wind, which resulted in the glider impacting a runway sign.
