What happened
On June 6, 2015, a student skydiver performed their first-ever jump from an altitude of 1,200 meters at the Krępa Słupska (EPSK) aerodrome. The jump was conducted using a parachute with an automatic deployment system (deployment bag/pilot chute). The student successfully exited the aircraft, and the main parachute deployed. However, once the canopy had inflated, the student observed that the slider had stopped halfway down the lines, causing the parachute to enter a spinning motion.
Rather than attempting to assist the slider's descent by braking and pulling the control lines multiple times, the student chose to cut away the main canopy and deploy the reserve parachute. Following instructions provided by an instructor, the student managed to land safely at the aerodrome.
The investigation
The investigation was conducted by the training organizer. The inquiry focused on the sequence of the deployment and the student's subsequent emergency procedures. The investigation examined the state of the parachute equipment and the actions taken by the student following the malfunction.
Findings
- The investigation could not determine the specific cause for why the slider stopped mid-way down the lines.
- The student did not attempt the recommended technique of braking and pulling the control lines to assist the slider's movement before deciding to deploy the reserve.
Safety action
Following the incident, the training organizer reviewed the event with all skydivers in the club. The discussion emphasized that in similar situations, jumpers should first attempt to assist the slider by braking and pulling the control lines several times. The emergency procedure of cutting away the main canopy should only be initiated if the slider fails to descend despite these efforts.
