The commercial pilot stated that the purpose of the flight was to apply chemicals to adjacent fields. After applying four loads of chemicals, the pilot flew the helicopter back to the landing pad, which was situated on top of a box-truck, to load more chemicals. While attempting to maneuver the helicopter onto the center of the truck's pad, the right skid became caught on an access hole that ground personnel use to refill the load. The pilot was unaware of the problem and attempted to reposition the helicopter by lifting the right skid. The helicopter dynamically rolled over off the back of the truck and collided with terrain. The pilot stated that there were no preimpact mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
Probable Cause: The pilot's inability to maintain helicopter control after its skid got caught on the landing pad while he was maneuvering the helicopter to land on it, which resulted in a dynamic roll-over.
