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 of the glider reported that, during a long distance ridgeline soaring flight, he encountered a loss of lift and dropped below the ridgeline. Unable to find another updraft, he was forced to land in an open field with tall grass. As the glider touched down, the landing gear struck a large hole that was concealed by the grass, shearing off the landing gear and causing a ground loop when the left wing struck the ground. The fuselage and tail were substantially damaged.
