Accidents and incidents In May 2016 a Skyleader 500 crashed in Rhoadesville, Virginia, United States, killing the two occupants of the aircraft. The Galaxy Rescue Systems ballistic parachute had been deployed, but the single front riser failed, leading to the parachute failure. The aircraft had been practicing slow flight and stalls and most likely entered a spin, from which the parachute was deployed. The aircraft was over maximum weight at the time of the accident. The GRS parachute model had never been tested in the air on this aircraft design and had only been ground tested once. A new double front riser system is now in use.
