Probable cause

The pilot landed on unsuitable soft terrain which caused the landing skid to sink into the ground. This resulted in a landing skid overload failure and nose over of the helicopter. Contributing to the accident was the soft terrain.

Analysis

The acft was air taxiing at 2 ft AGL when the instructor cut the power to simulate a power loss. According to the student and instructor, a normal landing followed; however, the acft nosed over. Upon exiting the acft they noticed they had landed on a dirt mount and the left landing skid had failed.
