What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot of the helicopter landed next to a refueling truck in order to conduct a "hot fueling" operation. At the end of the refueling, the pilot left the helicopter to assist the ground refueler with the fueling hose. When they were finished refueling the pilot started to walk back towards the helicopter. While walking back to the helicopter the main rotor blades "tipped" down towards the fueling truck and struck the top of the cab. Meanwhile the pilot moved quicker to the helicopter and he was able to bring the aircraft under control and shut down the engine. After seeing that the pilot was conscious, the ground refueler ran to the highway and waved for help.
