Event Location
Probable Cause
The pilot’s failure to maintain the proper airspeed and his exceedance of the glider’s critical angle of attack, which resulted in a stall/spin.
Full Narrative
The glider pilot reported that while maneuvering about 10,000 ft. mean sea level he "lost control" and the glider went into a spin, followed by a spiral. He added that he egressed from the glider, deployed his parachute, and was later rescued. The glider impacted terrain and was destroyed.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation.
