Analysis

The aircraft crashed during an external load operation at an elevation of about 6700 ft MSL in mountainous terrain. The pilot reported that the fuel gauge indicated 8 gallons remaining when he last checked it before the accident. Reportedly, he checked his instruments prior to letting a load down into trees, and he had no caution or warning lights. While setting the load down on the ground, he heard the turbine RPM decay. He moved about 25 ft right and 20 ft forward to clear the trees. During the landing, the aircraft touched down on sloping terrain and rolled over. There were no reported malfunctions of the aircraft engine or fuel system.
