What happened
On May 15, 2013, at approximately 16:18, a Cessna F 172 P departed Kempten-Durach aerodrome for circuit training with a pilot and an instructor on board. Shortly after, a Diamond DV 20 Katana departed for a local flight with two occupants.
At approximately 16:49, as the pilot of the DV 2-0 Katana was completing a right-hand turn to enter the crosswind leg for runway 25, the pilot observed an aircraft approaching from the left. Despite an evasive maneuver to the right, the two aircraft collided. An eyewitness reported that the right wing of the Cessna F 172 P struck the lower fuselage of the DV 20 Katana during a left-hand turn. The impact caused the Cessna F 172 P to lose its left wing, resulting in a fatal crash into the ground. The pilot of the DV 20 Katana was able to perform an emergency landing in a field approximately 6.6 kilometers away.
The collision resulted in two fatalities for the occupants of the Cessna F 172 P and two minor injuries for the occupants of the DV 20 Katana.
