What happened
On April 13, 1996, a Cessna 150 M was conducting a training flight near Bermel, Germany. The flight, consisting of an instructor and a student, was intended for practicing emergency landing procedures at the Koblenz-Winningen airfield.
During the fourth training exercise, the student pilot flew over a row of trees toward a field that appeared suitable for a landing, maintaining a 30° flap setting. The instructor then instructed the student to perform a go-around. As the engine power was increased and the flaps were retracted to 20°, the aircraft failed to gain altitude. Instead, the aircraft began to descend, and airspeed decreased.
As the instructor took control of the aircraft, a high-voltage power line was identified crossing the flight path. In an attempt to maneuver around the obstacle, the instructor initiated a turn. During this maneuver, the left wingtip made contact with the ground, causing the aircraft to nose over and capsize. Both occupants were able to exit the wreckage, which came to rest on its back, without injury.
The investigation
The BFU investigation focused on the flight sequence and the aircraft's performance during the go-around attempt. The investigation established that the aircraft sustained heavy damage, and there was minor damage to property on the ground. The investigation also noted that the crew had not reported any existing technical defects regarding the aircraft prior to the accident.
