Analysis

The fuel pump warning light came on and the pilot headed for a local airport. Enroute, the engine surged and flamed out. During the landing, the rotor blades hit trees, and the helicopter made a hard landing. The fuel gage indicated 11 gallons. Later the gage indicated 14 gallons, but five gallons total were drained from the tank. With the tank empty, the gage indicated 8 gallons. There was no fuel in the airframe filter. After the fuel boost pump was turned on, there was fuel in the HP filter. Pilot stated in report, 'due to the faulty fuel boost pump and inaccurate fuel gage reading, aircraft sustained engine failure due to fuel starvation'.
