After what seemed to the pilot to be a normal touchdown, the aircraft suddenly became airborne again and, before he was able to open the throttle to go around, the aircraft landed heavily on its nosewheel. The front forks bent backwards and the propeller struck the ground. The aircraft then left the runway and came to a halt. The pilot, who was uninjured, made the aircraft safe and vacated it normally.
The pilot considered that the accident was caused by him relaxing after the touchdown, and he was not able to react quickly enough to a gust of wind which had caused the aircraft to become airborne again.
