NTSB Identification: GAA17CA386
14 CFR Part 91: General Aviation
Accident occurred Wednesday, July 05, 2017 in Ely, NV
Probable Cause Approval Date: 09/22/2017
Aircraft: ALEXANDER SCHLEICHER GMBH & CO ASH 31 MI, registration: N31MX
Injuries: 1 Minor.
NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
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.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
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.
Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Reno, Nevada

Talking to another glider pilot at Ely, who elected not to fly that day, conditions were turbulent on the 5th. The glider involved entered a spin and for unknown reason pilot did not recover from the spin, electing to bail out. White debris is visible on the mountain from Ely.
