What happened
On 28 October 2007, an experienced parachutist participating in an accelerated free fall instructional jump was involved in a fatal accident at the Carletonville skydiving drop zone in Gauteng. The individual, who had 5,300 jumps and 23 years of experience in the sport, was operating under a Mirage G4 parachute canopy.
During the descent, the parachutist attempted a swoop landing, a high-speed maneuver involving a 270-degree turn to generate momentum. While using the rear risers to flatten the glide path, a momentary fumble occurred with one of the back risers, causing the parachute to jolt. In an attempt to correct the flight path, the parachutist transitioned from the risers to the brakes and then back to the risers. This sequence occurred at a critical altitude, resulting in a collision with the ground at an approximate 45-degree angle. The impact forces at the high forward and descent speeds rendered the accident non-survivable, resulting in one fatality.
The investigation
Investigators examined the equipment and the sequence of the maneuver. The Mirage G4 parachute and its components were inspected by two master riggers, both of whom found the equipment to be in a serviceable and satisfactory condition. Meteorological reports indicated that weather conditions at the time of the accident were fine.
Findings
- The initial setup and the glide path during the maneuver appeared normal.
- The use of back risers to flatten the glide angle was consistent with a swoop landing attempt.
- A premature release of one riser caused a loss of concentration and disrupted the approach path.
- The parachutist attempted to use the brakes and then returned to the risers at a dangerously low altitude.
- The parachutist misjudged the initial height required to begin the swoop maneuver.
Safety action
Following the investigation, a recommendation was made to the South African Skydiving Association (SAPA) regarding the risks associated with high-speed canopy piloting. The report suggested implementing educational programs and skill-based testing to ensure jumpers are properly trained in the complexities and dangers of high-speed landings.
