## Analysis

THE HELICOPTER WAS LIFTING OFF WHEN THE LEFT SKID STUCK IN THE DIRT. THE ACFT DID A DYNAMIC ROLLOVER WHEN THE LEFT SKID REMAINED STUCK AS THE PILOT ATTEMPTED TO TAKEOFF. THE PILOT HAD JUST ON-LOADED TWO PASSENGERS BOTH ON THE LEFT SIDE. WEATHER WAS NOT A FACTOR AND NONE OF THE OCCUPANTS WERE INJURED.
