What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot of the helicopter had just finished a 14 CFR 137 aerial application and approached the re-supply truck; landing from the west (heading east). Upon touchdown, the pilot stated he felt "something wasn't right." The pilot stated he felt a very slight rearward tipping sensation and applied slight forward control input. The pilot stated the helicopter began to yaw to the left and slid off the re-supply truck landing pad. An eyewitness on the ground stated the helicopter's right skid impacted a 4-inch re-supply hose, after yawing, and bent it's bracket backwards. The re-supply hose was undamaged. At this point, the pilot stated the helicopter pitched forward, continuing a yaw to the left. The pilot stated the helicopter twisted and rolled off the truck, landing on its left side. The helicopter's main rotor hit the ground as a result, destroying the aircraft. The pilot stated he shut down all switches and climbed out of the helicopter. The pilot sustained no injuries. During the investigation, no aircraft anomalies were found. All control inputs made by the pilot were in accordance with the manufacturer's limitations. The accident investigation was closed with no further action.
