What happened
On May 20, 2017, a student skydiver performed her first solo jump using an automatic deployment parachute system (SL-1). The jump proceeded without incident until the landing phase at the Przasnysz (EPPZ) aerodrome. Throughout the descent, the student was in radio contact with an instructor on the ground, who provided navigation and landing instructions.
While the student successfully executed the approach and performed the correct flare maneuver as instructed, an error occurred at the moment of touchdown. Upon contacting the grass, the student's legs became uncoupled. The student attempted to run forward for two steps, which resulted in a tripping motion.
The investigation
The investigation focused on the physical mechanics of the landing and the student's adherence to standard landing procedures. Medical personnel were dispatched to the scene, and the student was transported to a hospital. Clinical examinations revealed a sprain/tear of the ankle joint and damage to the plantar cushion.
Findings
- The primary cause of the injury was landing with legs uncoupled and knees unbent.
- The student followed the radio commands for the approach and flare correctly, but failed to maintain proper leg positioning during the final impact.
