A glider fell in a spin from an altitude of 200 meters and crashed in a field at a few kilometers from Menuma Glider Port, Kumagaya city, Saitama prefecture, after a half hour of flight. The sole pilot, the captain of Aviation Club of Waseda University, received fatal injury. The accident was happened in the first day of the 32nd Kanto Student Glider Competition, which was scheduled from 10th to 16th, October. The competition was terminated due to this accident.

It is highly probable that in spite of the control to recover from the stall at low altitude, the Glider stalled again; started spinning and crashed.
It is somewhat likely that the Glider stalled at low altitude because of the steep turn at low speed and that the stall was attributable to the Pilot who did not fully familiarize himself with the flight characteristics of the Glider whose CG position was set to near the aft limit position.
