Narrative:The pilot arrived after 12.00 with the sailplane in a trailer, and started to assemble the sailplane and prepare it for the flight. He proceeded with the pre-flight check.
Nobody recalls he asked for help.
He was seen pushing the sailplane towards the start position. There were a few sailplanes in front of him waiting in line for the start.
There were 13 winch starts and 2 aerotow starts performed before OO-YEB.
When OO-YEB’s turn came to take-off, the pilot decided to wait somewhat, because returning pilots reported the thermal conditions were not optimum. He sat in the cockpit, waiting, with canopy open. He intended to perform a small navigation flight.
When the pilot decided to take off, he waved to the ground team that connected the winch cable to the sailplane cable.
The wing was raised to the horizontal position by the “wing tip-runner”. The type of sailplane was radioed by the start leader to the winch man, with the request to tauten the cable. This was confirmed by the winch man.
The sailplane moved forward a few meters, due to the tautening of the cable, before the actual start.
As witnessed by the flight instructor, the initial climb occurred normally; there was no lateral drift, and no sign of abnormal speed build-up. The winch man saw the sailplane coming, and when it reached the release point, the winch man cut the power of the winch. The winch man noticed that the tow cable did not detach from the sailplane. When the sailplane came vertical above him, the
winch man activated the emergency cable cut-off. The system worked, and the cable was cut; the remaining length was 525m. Witnesses showed the sailplane in a steady dive, nose down, without any lateral movement of the sailplane.
The sailplane crashed 310m away from the winch in a very steep dive.
During the flight, the pilot noticed there was something wrong, as he un-strapped himself and tried to open the canopy. The pilot was fatally injured on impact.
Causes.
The cause of the accident is the pilot’s failure to adequately connect and secure the elevator control during assembly and failure to perform an adequate pre-flight check.
