Accident Sequence
According to the safety pilot's written statement, the helicopter pilot was performing a simulated forced landing exercise with the intent to conduct a power recovery. The pilot initiated a flare at approximately 50 feet above ground level. As the helicopter descended, at about 20 feet, a gust of wind caused the descent rate to increase. The safety pilot then assisted in the attempt to regain control, and the rate of descent was reduced. However, the aircraft continued to descend and one skid made contact with a raised rock area approximately one foot in height. The safety pilot reported that the helicopter quickly tipped over onto its left side, with no opportunity to recover.
Safety Pilot's Observations
The safety pilot noted that they had seemingly recovered control at a height of 1–2 feet, but the uneven terrain, specifically the raised rock area, caught the skid and precipitated the rollover. The safety pilot's statement indicated that the sequence of events left no room for corrective action once the skid contacted the rock. The accident occurred during a training maneuver, and the safety pilot was aboard to oversee the exercise.
