NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The commercial certificated pilot departed a survey camp in a high skid-equipped helicopter, on an air taxi flight to survey potential exploration sites. The director of operations said the pilot told him that he was flying about 70 feet above the ground at 50 knots when he began a descending 180 degree left turn to land in an area of flat open tundra. The pilot indicated the airspeed decreased during the turn, and the helicopter shuddered and developed a high rate of descent. The pilot applied collective pitch and power, but the rate of descent increased. The right landing gear skid contacted the ground, and the helicopter rolled onto its right side. The pilot told the director of operations that the wind conditions were about 8 knots from the northeast.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to correct a settling-with-power condition during a helicopter landing flare/touchdown, resulting in a hard landing and roll over.
