What happened
On July 12, 2015, a skydiver with 1,553 previous jumps performed their first jump of the day from an altitude of 4,000 meters. The jump was part of a scheduled RW-3 task. At approximately 1,000 meters, the main parachute was deployed successfully. The descent concluded with a landing outside the perimeter of the Piotrków Trybunalski (EPPT) aerodrome.
During the final stages of the landing sequence, at an altitude of approximately 50 meters, the skydiver was holding the rear risers while simultaneously gripping the steering toggles. As the altitude decreased to roughly 15 meters, the skydiver released the rear risers. At that precise moment, the left steering toggle slipped from the skydiver's hand. This loss of control caused the parachute to turn sharply, resulting in a ground impact that caused serious injuries to the skydiver.
The investigation
The investigation focused on the sequence of maneuvers performed by the skydiver during the final 50 meters of the descent and the mechanical/manual handling of the parachute controls during the landing phase.
