The glider crashed inverted on the ground at Sion Airfield - LSGS after an aborted take-off. The pilot (63) suffered head-injuries. The glider sustained substantial damages.
Causes
The accident, in which the large glider pitched up at the beginning of the tow and overturned, was caused by the the glider topped out at the beginning of the tow, because the glider pilot did not unhook the tow cable when the glider touched down with the wing tip while taxiing. Subsequently, the glider moved sideways so that the pilot lost control of the aircraft during the takeoff.
During the investigation, the procedure at Sion airport, which requires that the the tow path not to be aligned with the runway axis from the start, was identified as a factor to risk.
