Confidence Rating: Accident investigation report completed and information captured
Shortly before 9 am, the helicopter took off with five people including two children on board for a pleasure flight towards Montreux and then the Dents du Midi.
On return from the flight, the helicopter was on final for runway 18, at the end of which the pilot executed a left turn out of ground effect to reach the tarmac of the departure hangar. During this turn, the pilot was unable to stop the maneuver and the helicopter rotated several times around the left yaw axis before landing hard on the runway edge.
The helicopter stabilized in the grass with the right landing gear collapsed. No occupants were injured.

The loss of yaw control was due to an inappropriate foot action at the time of the turn stop in relation to the power demanded. The pilot's final reaction of reducing power by lowering the collective prevented more serious damage. A full right kick would have stopped the turn and prevented damage to the aircraft.
