Primary finding
Probable cause
The pilot's failure to properly plan the approach to the airport, which resulted in an in-flight collision with a tree. A factor was the gusty wind conditions.
Investigator assessment
Analysis narrative
While returning from a local flight, the pilot realized that the glider did not have enough altitude to reach the airport. He identified a farm field to perform a forced landing to. While on approach to the field, and while gliding over trees, the glider was "hit by a gust of wind," and entered the tree tops while traveling about 50 mph. The left wing struck a large tree, turning the glider 180 degrees, before the nose pitched down and impacted the forest floor. The pilot reported no mechanical deficiencies of the glider, and reported that the winds were "very gusty" on the day of the accident.
