Aviation Accident Summary WPR22LA150

Valyermo, CA, USA

Aircraft #1




The pilot of the glider reported that, while in thermal flight, he made a turn to the south to follow a ridgeline. Before he reached the top of the mountain, the glider experienced a loss of lift. To compensate, he maneuvered the glider away from terrain and encountered additional sink. While maneuvering the glider toward lower terrain, the right-wing tip struck a tree. The glider struck additional trees before it impacted terrain and came to rest between two trees. The glider sustained substantial damage to the right wing and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation.

Probable Cause and Findings

The gliders encounter with atmospheric conditions where the lift was not sufficient to maintain flight and subsequent impact with mountainous terrain.
