Accident to the Lambert Mission M106 identified 63ASZ on 22/08/2020 at Ceyssat
Atterrissage dur dans un champ, remise des gaz, perte de contrôle, collision avec des arbres
The pilot undertook a flight to a field which he had previously spotted on foot and at the edge of which he had installed two windsocks which he had made. The field was on a slope in a hilly environment and was bordered by trees. The warning tape used for the windsocks probably became entangled in the vegetation and fence, causing the pilot to have an erroneous perception of the direction and strength of the wind. The pilot thus undertook a landing with a significant tailwind component without being aware of it. In addition, with a downwind leg close to the field, after the U-turn, the microlight was on the axis of the field at a low height. The pilot then had very little time, about fifteen seconds, to stabilise the final. In this context he was unable to keep control of the microlight which hit the ground hard and bounced, probably due to an aerological phenomenon.
The pilot then went around but did not manage to gain height or speed. This can be explained by the low speed of the microlight after the bounce, the flaps still being fully extended, and the tailwind component. The upward slope of the field and the proximity of obstacles may also have caused the pilot to increase his attitude significantly, thus degrading the climb gradient and causing the loss of control of the microlight which veered to the right before colliding with trees.
