What happened
On May 13, 2018, a tandem parachute jump was conducted from an altitude of 3,000 meters. The descent proceeded normally following the deployment of the parachute. However, during the landing phase at EPZP, while the occupants were at an altitude of approximately 15 to 20 meters, the parachute canopy experienced an unexpected collapse. At the time of the incident, a wind of approximately 4–5 m/s was blowing from the northeast (070–090 degrees).
Although the canopy managed to reinflate and regain its shape before impact, the tandem pilot was unable to sufficiently reduce the rate of descent despite performing a correct braking maneuver. The resulting hard landing caused the passenger, a woman approximately 65 years of age, to sustain significant injuries. While she was able to move under her own power immediately following the impact, emergency medical services were summoned to the scene.
The investigation
The PKBWL investigation reviewed the circumstances of the descent and the environmental conditions at the time of landing. The investigation confirmed that the tandem pilot was fully qualified, holding valid tandem certificates, insurance, and medical certification, with extensive experience totaling 1,700 jumps (including approximately 500 tandem jumps). The medical evaluation of the passenger revealed two fractured vertebrae, which required hospitalization and surgical intervention.
Findings
- The primary cause of the incident was the occurrence of a sudden gust of wind at a low altitude.
- The landing was characterized by a high rate of descent due to the canopy's momentary loss of inflation.
