What happened
On August 15, 2019, a skydiver was performing a jump as part of a scheduled training session at the Chrcynno (EPNC) aerodrome. This was the second jump of the day and the 630th jump in the individual's career. After completing the jump, the skydiver entered the landing pattern, following the standard procedure of establishing a round and transitioning to the final approach.
During the final approach, specifically between approximately 100 and 70 meters of altitude, the skydiver attempted to increase canopy drive. While the flight speed under the canopy was standard, it was higher than during previous jumps or periods of windier weather. The skydiver attempted a standard flare at the usual altitude and with the expected dynamics; however, the canopy failed to decelerate effectively, preventing the flight from leveling out. Despite the skydiver applying stronger input via the toggles, the canopy remained too fast. Consequently, the landing occurred with a slight leftward turn, and the skydiver impacted the ground on both legs with significant pressure applied to the left ankle.
The investigation
The investigation examined the flight dynamics, the atmospheric conditions at the time of the landing, and the proximity of obstacles to the landing zone. The inquiry established that the skydiver sought medical attention at the drop zone, where a rescuer applied a splint and bandaged the swollen ankle. Subsequent hospital examinations, including X-rays, ruled out fractures but confirmed a severe ankle dislocation and torn ligaments, requiring a cast and rehabilitation.
Findings
- The primary cause of the accident was likely variable atmospheric conditions, specifically involving thermal activity and shifting wind directions.
- The increased canopy speed during the final approach prevented a proper flare.
- The proximity of the landing to the drop zone's structures and the control tower may have contributed to the circumstances of the incident.
