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 glider pilot was practicing cross country maneuvers, but was forced to alter his destination due to weak lifting conditions encountered during the flight. According to the pilot, on his return leg to the departure airport he "started to get low" and began looking for an alternate landing site. While at 1,000 feet agl the pilot proceeded towards a farmer's field to initiate an off-field landing. The pilot stated that he may have initiated a brief turn at the last minute to search for another landing area, but could not recollect any additional events leading up to the accident. The glider impacted trees and subsequently came to rest on the ground about 100 yards south of a tree line. Post-accident examination of the airplane revealed substantial damage to the right wing and empennage section. The pilot reported no pre-impact mechanical malfunctions or failures with the glider that would have precluded normal operation.
