What happened
On September 1, 2018, an experienced skydiver with 250 jumps performed a descent from an altitude of 4,000 meters. The initial exit from the Spadochron Pilot 188 and the subsequent freefall phase proceeded without incident. However, as the jumper initiated the deployment of the main canopy at approximately 1,100 meters, the lines became twisted. This malfunction caused the parachute to enter a spinning motion.
To rectify the situation, the jumper released the main canopy and deployed the reserve parachute. The descent concluded with a landing in the vicinity of the Piotrków Trybunalski (EPPT) airfield, and the individual sustained no injuries.
The investigation
The investigation, conducted by the operator, examined the sequence of the deployment and the physical mechanics of the canopy malfunction. The inquiry focused on the stability of the jumper during the critical deployment phase at 1,100 meters.
Findings
- The primary cause of the malfunction was the asymmetrical body position maintained by the skydiver during the opening of the parachute.
- The operator addressed the incident by discussing the event with other skydivers present at the airfield, emphasizing the necessity of maintaining a symmetrical body position during deployment to prevent line twists.
