The pilot said he landed the helicopter on the ramp and was unaware that the area was covered with ice because of darkness. He turned off the governor, placed the cyclic and collective friction locks on, and brought the engine RPM to 80 percent for cool down. The helicopter began to turn 90 degrees counter-clockwise and slide backward. The pilot applied right pedal, which countered the yaw; however, the helicopter continued to slide backward on the ice. The helicopter then contacted a snowbank and rolled over. The pilot said he did not experience any mechanical malfunctions.
