28-Jun-15 VH-RBO Robinson R22 Daly Waters, Australia

When at about 100 ft above ground level and an airspeed of 40 knots, the pilot conducted a turn into wind. As the helicopter turned, the pilot received a low rotor rpm warning. The helicopter collided with terrain and rolled onto its side, resulting in substantial damage (photo). The pilot sustained minor injuries.

Final report says “The Robinson Helicopter Company Safety Notice SN-24 states that rotor stall due to low RPM causes a very high percentage of helicopter accidents. These mostly occur close to the ground during take-off and landing. Safety Notice SN-10 reminds pilots to have their ‘reflexes conditioned so they will instantly add throttle and lower collective to maintain RPM in an emergency’.”
