What happened
On July 8, 2017, a student skydiver was performing a training jump from an altitude of 4,000 meters to practice freefall techniques. The jump began normally, and the descent proceeded without incident from the moment the skydiver exited the Spadochron Navigator 220.
As the skydiver approached the landing area at the Piotrków Trybunalski (EPPT) airfield, the final approach was characterized by high forward speed and an increased rate of descent. During the landing sequence, at an altitude of approximately 15 meters, the skydiver failed to fully deploy the landing toggles. The skydiver subsequently impacted the ground with legs spread wide while maintaining an elevated vertical descent rate. This impact resulted in a fracture of the right fibula.
The investigation
The investigation was conducted by the operator. The inquiry focused on the descent profile and the configuration of the parachute during the final moments of the landing. The investigation established that the skydiver's landing posture and the parachute's aerodynamic state contributed to the injury.
