Cat. 2 investigation report: simplified-format report, adapted to the circumstances of the occurrence and the investigation stakes.

The pilot planned to make a local flight with one passenger, departing from Nancy-Malzéville aerodrome. He distanced himself from the south-east area of the aerodrome where a model aircraft event was taking place, and taxied to the intersection of runways 08 / 26 and 04 / 22. He took off from the remaining length of runway 04 (approx. 800 m). During the initial climb, after passing the end of the runway, he lost control. The microlight collided with the ground and burst into flames upon impact. It was almost completely destroyed by the fire.
The pilot lost control of the microlight during the initial climb. The proximity to the ground did not enable him to regain control of the aircraft.

According to the witness who was closest to the accident site, the engine was operating up to impact. The examination of the wreckage was unable to determine if it was delivering full power. It is not possible to rule out that the fuel valve was in the closed or partially closed position during the start of the flight, reducing the supply of fuel after several minutes of engine operation.
