On 19 November 2018 at 0943Z, the glider was towed from Runway 33 at Gariep Dam Airfield (FAHV). According to the tow pilot, there was mild turbulence during the climbing phase of the flight when routing north-west of the airfield. The tow pilot completed one orbit to the left before releasing the glider at 1700 feet (ft) above ground level (AGL).
The glider was observed climbing slowly and routing towards the ridge which is situated directly north of the airfield. At 0954Z, the glider made a right turn with the right wing dropping. The glider stalled and entered a spin for about half a rotation. The glider appeared to be accelerating before impacting the terrain 1.3 nautical miles (NM) north of the airfield. The aircraft was destroyed on impact and the pilot was fatally injured during the accident sequence.

The investigation revealed that it was likely that after the release from the tow aircraft, and while performing a climbing turn in proximity to a ridge line and in mild turbulent weather condition, the glider stalled and entered a spin. However, the pilot could not recover, resulting in the glider impacting the ground.
