What happened
On June 10, 2015, a student skydiver was performing their second-ever parachute jump at the Bielsko-Biała (EPBA) airfield. The jump, conducted under the supervision of a training organizer, proceeded normally from the moment of aircraft separation until the final approach to the designated landing zone.
As the student approached the ground at an altitude of approximately 5 meters, they pulled the steering lines of the Mars 330 parachute. This action caused a reduction in forward speed—with wind speeds recorded at 3 m/s—and a slight increase in the vertical descent rate. Upon impact with the ground, the student's legs were held together; however, as they tumbled during the landing, they attempted to brace themselves with an arm, resulting in minor injuries.
The investigation
The investigation focused on the mechanics of the landing and the student's technique during the final descent. The inquiry established that the student was in the very early stages of training, having completed only one previous jump earlier that same day.
Findings
- The primary cause of the incident was the adoption of an incorrect landing posture.
- The manipulation of the steering lines at a low altitude altered the parachute's flight characteristics, specifically increasing the vertical descent speed.
Safety action
Following the incident, the training organizer reviewed the event with all active skydivers. Additionally, the organization implemented supplemental training sessions specifically focused on proper landing techniques for students.
