Eyewitnesses saw the aircraft flying in various directions at 1000-3000m in the Lake Constance/Bodensee area. At 10:20 when flying between Romanshorn and Arbon, the aircraft was seen flying in level flight when it suddenly stalled and went into a spin. The aircraft struck the water in a very steep dive.
PROBABLE CAUSE: "The stalling of the aircraft following a loss of airspeed, whereupon it unintentionally went into a spin. In view of insufficient altitude, it was not possible to level off the aircraft."
