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 after departing for local area soaring, he found himself in “dying lift”. He attempted to recover altitude but was unsuccessful. He said that the glider encountered additional “sink” and did not have sufficient altitude to reach the airport. During the forced landing on rough terrain the left wing sustained substantial damage. The pilot reported that there were no pre-accident mechanical malfunctions or failures with the glider that would have precluded normal operation.
