Accidente fatal de DG-100 en Schäner Berg, Suiza durante vuelo de entrenamiento

El 8 de marzo de 1980, un DG Flugzeugbau DG-100 se estrelló en Schäner Berg, Suiza, durante un vuelo de entrenamiento. El piloto despegó del aeródromo de Schänis a las 13:37 hora local y fue escuchado por última vez a las 14:30, informando su posición sobre Schäner Berg. Los restos fueron descubiertos dos días después, el 10 de marzo, a una altitud de 1260 metros. El piloto sufrió heridas mortales y el planeador fue destruido. La causa del accidente sigue siendo desconocida.

1. Aerotow training flight: The pilot departed Schänis at 13:34–13:37 on an aerotow in his recently acquired DG-100 for a solo training flight.
2. Low type experience: The pilot had limited recent experience on the DG-100, with only three prior flights on type and the last one about five months earlier.
3. Aft CG within limits: The glider’s center of gravity was in the rear part of the allowable range, a condition that could make stall and wing drop more abrupt.
4. Local soaring Schäner Berg: After release, the pilot flew locally and was reported and heard on the radio around 14:30 as being over the Schäner Berg ridge in good lift conditions.
5. Unknown loss of normal flight: For unknown reasons while flying near terrain at Schäner Berg, normal controlled flight was disrupted, leading to a high-speed descent toward the slope.
6. High-speed impact with slope: A witness saw the glider approaching the west slope below the Federispitze at high speed in a steep flight path before it disappeared behind trees and a loud bang was heard.
7. Crash - fatal: The glider struck the steep west slope of Schäner Berg at high speed around 14:30, was destroyed, and the pilot was fatally injured.
