Ka 6 incident during outlanding near Büren a.A. on May 26, 1969

On May 26, 1969, an Alexander Schleicher Ka 6 CR experienced an incident near Büren a.A., Switzerland. The pilot, participating in a competition training camp, attempted an outlanding but stalled during a low-altitude turn. Fortunately, there were no injuries or fatalities reported. The official investigation confirmed the sequence of events leading to the incident.

1. Cross-country task flight: During a competition training camp flight, the pilot was flying a cross-country task in the Ka 6 HB-691.
2. Late outlanding decision: The pilot decided too late to perform an outlanding instead of continuing the task.
3. Low altitude approach: By the time the outlanding decision was made, the glider was already at low altitude, leaving little safety margin for maneuvering.
4. Low-altitude turn: The pilot initiated a turn close to the ground while setting up for the outlanding.
5. Stall in turn: During this low-altitude turn, the glider stalled and departed controlled flight.
6. Crash - no injury: The glider impacted the ground near Büren a.A. after the stall, but there were no injuries to the pilot.
