Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot stated that the glider had been aloft for about 30 minutes prior to experiencing a loss of lift. After selecting a field for an off-airport landing, the pilot maneuvered the glider towards the field, and upon touchdown, the left wing contacted a pole. The glider subsequently pivoted left and came to rest upright, resulting in substantial damage to the tail boom. The pilot stated there were no mechanical malfunctions or anomalies of the glider that would have precluded normal operation.
