Accident to the autogyro Magni Gyro M16 identified 12CO on 14/08/2021 at Arceau-Arcelot
Loss of altitude, collision with ground, post-impact fire, in instruction
The instructor, accompanied by the student pilot, took off from the microlight strip at around 09:30. During the flight, although, according to the student pilot, the engine, rotor and speed parameters were nominal, the gyroplane gradually lost altitude until it collided with the ground.
The gyroplane’s excess load and the meteorological conditions on the day of the occurrence reduced its performance. However, this degraded performance does not on its own, explain the loss of altitude described by the student pilot.
The flight path described by the student pilot seems to correspond to flight on the backside of the power curve. However, in the absence of additional data to the student pilot's statement, the investigation was unable to confirm this hypothesis.
The investigation was also unable to understand why the instructor did not seem to react to this abnormal situation.
