Accident to the Schempp Hirth Janus C registered F-CLUI on 23/10/2023 at Bagnères de Luchon

The instructor terminated the flight shortly after taking off as he believed that the conditions were not suitable for an instruction flight. During the final approach, after positioning the flaps in the landing configuration, he very probably kept his hand on the flap control instead of returning it to the airbrake control. The airbrakes, half open in the base leg, very probably retracted without the instructor realising this. During the flare, the instructor was unable to land. The glider bounced and flew over the length of the runway. After passing over the fence at the end of the runway, the instructor banked the glider so that the right wing would touch the ground and the glider would make a ground loop in order to stop before the obstacles.
