On November 24, 1995, at 1050 hours Pacific standard time, a Robinson R-22HP helicopter, N90452, crashed on the landing ramp at the Fresno airport in Fresno, California. The helicopter received substantial damage and the two occupants were not injured. Visual meteorological conditions existed at the time. The aircraft had departed an hour earlier for a local pleasure flight. According to the operator, at the bottom of the approach to the landing area, the helicopter started backing up. The heels of the skids caught on the asphalt and the tail rotor hit the ground damaging the aircraft. The pilot stated in his report that before he put the helicopter on the ground from a hover, it started moving back slowly and descended. He applied power to stop the slow descent when one of the skids touched the ground. The helicopter started accelerating backwards and collided with the ground.
