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 reported that, during the return flight to the airport, the glider encountered more downdrafts than he expected, and that the glider did not have sufficient altitude to reach the airport. During the subsequent forced landing into trees and shrubby, the glider’s fuselage and wings sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures of the glider that would have precluded normal operation.
