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 in the glider reported that, during the return flight to the airport, he encountered a higher sink rate than expected and did not have sufficient altitude to reach the airport. During an emergency landing in a fruit orchard, the glider landing gear contacted utility pole wires, which resulted in substantial damage to the fuselage and wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation.
