Incident Overview
The pilot reported that the helicopter was landing on a concrete pad at a construction site. The helicopter was not completely positioned on the pad; the aft section of the skids were hanging off the edge. As the pilot lowered the collective, the helicopter rocked backward and the tail rotor skid made contact with the ground.
Sequence of Events
In response to the tail rotor skid touching the ground, the pilot abruptly attempted to pull the helicopter back into a hover. This action caused the helicopter to move forward and start rolling to the right. Despite the pilot's efforts, the rolling movement could not be stopped. The helicopter struck the ground and came to rest on its right side.
Outcome
The final resting position of the helicopter was on its right side. No further details regarding injuries or damage were provided in the pilot's report. The accident occurred during a landing on a concrete pad at a construction site.
