What happened
On October 1, 2017, a student skydiver was performing their eighth jump at the Kazimierz Biskupi (EPKB) airfield. The jump was part of a training progression, marking the student's third solo jump following the completion of an AFF course. The jump was conducted from an altitude of 4,000 meters using a Prime 260 parachute with a weight load (WL) of approximately 0.88.
The deployment of the main canopy and the execution of the landing pattern were performed correctly. However, as the student approached the ground, they misjudged their altitude. At approximately 5 meters above the ground, the student performed an improper maneuver by pulling the parachute and then releasing the toggles to brake again. This sequence resulted in a landing at an increased velocity with their legs spread apart.
The investigation
The investigation was conducted by the user/operator. The inquiry focused on the sequence of maneuvers performed during the final stages of the descent and the student's altitude assessment.
Findings
- The primary cause of the accident was landing at an increased speed due to an improper altitude assessment and subsequent maneuvering.
- The student sustained a displaced ankle dislocation and a fracture of the fibula.
Safety action
Following the incident, the operator reviewed the event with instructors and skydivers, emphasizing the necessity of maintaining a proper landing posture.
