Accident to the Robin HR100/250 TR registered F-HRDM on 12/06/2021 at Wambrechies

The day before the accident, the pilot, his partner and a friend performed a flight between Béziers-Vias airport (Hérault) and Lille - Marcq-en-Barœul aerodrome (Nord). On arrival, they refuelled and spent the night near the aerodrome.

Shortly after take-off, the pilot reported over the frequency that he was going to land on the reciprocal QFU due to a problem in the cabin. During the turn-around, the pilot lost control of the aeroplane while making a steep banked turn in the initial climb phase, which offers few safety margins.
The investigation was unable to identify the problem reported over the frequency:
ˆ The hold door may have opened during the take-off run on the grass runway. Nevertheless, this type of event does not require an immediate landing;
ˆ The appearance of incapacitating smoke on board seems unlikely due to the results of the autopsies and analyses performed on the victims. However, an inappropriate reaction to sudden damage to an electronic device or accessory cannot be ruled out.
