Accident to the Guimbal Cabri G2 registered F-HPTI on 03/04/2021 at St-Georges-de-Reneins

Shortly after take-off, the helicopter jolted and yawed and a clacking noise was heard. The instructor, thinking that the failure was minor, turned around to fly back to the area from which they had taken off. During this manoeuvre, the engine power reduced, possibly due to a sealing fault at the valves of one of the cylinders. The instructor then decided to make an immediate landing, with a tailwind of around 15 kt. During the running landing in a field with loose soil, punctuated with grooves and covered with a tarpaulin, the helicopter first tipped forward and then onto its side.
