Power loss during initial climb leads to forced landing and collision at Lognes-Emerainville (F-GLKV)

Flight Details and Accident Sequence On July 25, 2013, at approximately 13:30 local time, a Robin DR400-120 with registration F-GLKV was conducting a dual-command training flight from Fontenay-Trésigny to Lognes-Emerainville. The aircraft was operated by a club and carried an instructor and a student pilot. During the flight, the student performed a touch-and-go landing on runway 26 at Lognes-Emerainville. During the initial climb, at an estimated altitude of 200 to 300 feet, the instructor noticed that the engine was no longer providing nominal power and could not maintain level flight. After checking the throttle, magneto selector, carburetor heat, electric pump, and fuel valve, the instructor took control and turned right to reach a clear area. The aircraft landed at low speed in a clearing by a lake. During the rollout, the plane struck a reinforced concrete wall hidden by vegetation, causing the wings to be torn off and the fuselage to fall into the lake. Both the student and the instructor were injured, and the aircraft was destroyed.
