Accident Overview

On 3 June 1966, a Schleicher Ka-6 glider, registration HB-634, was involved in an accident near Petit-Martel in the canton of Neuchâtel, Switzerland. The pilot, who was the sole occupant, was performing a field landing when the incident occurred.

Sequence of Events

During the landing approach, the pilot noticed a stake hidden by tall grass at the last moment. In an attempt to avoid the obstacle, the pilot initiated a left turn. However, as the glider banked, the low wing was braked by the vegetation and made contact with the ground. This caused the pilot to lose control of the aircraft, which subsequently crashed into the field.

Aftermath

The pilot emerged from the accident without injury. The glider sustained damage as a result of the impact.

Investigation
