The pilot had landed the helicopter next to the refueling truck to conduct a "hot refueling." At the end of the refueling, the pilot left the helicopter to assist the ground refueler with the hose. The pilot said he heard an abnormal noise. The helicopter began to vibrate. The pilot went to neutralize the flight controls. The helicopter bounced and knocked the pilot down as he grabbed the controls. The main rotor dipped down striking the refueling truck and causing damage to the helicopter main rotor blades, the tail boom, and the truck cab. The pilot got up and shut the helicopter down. The pilot reported that a gust of wind came up causing the helicopter rotor blade to dip down and strike the truck. An examination of the helicopter showed no anomalies. Approximately 23 minutes after the accident, the Aviation Routine Weather Report (METAR) for Bryce Canyon, Utah (BCE), 075 degrees at 28 nautical miles from the accident scene, reported winds as 210 degrees at 19 knots with gusts to 27 knots. Approximately 34 minutes prior to the accident, BCE METAR reported a peak wind of 180 degrees at 30 knots.
Probable Cause: the pilot's failure to maintain aircraft control. Factors contributing to the accident were the high winds, the gusts, and the refueling truck.
