BELL HELICOPTER TEXTRON 206
Same as Factual Information
The helicopter pilot reported that after a lengthy search and rescue mission he was headed back to the airport when the low fuel light illuminated, which meant there was about 10 minutes of fuel remaining. The pilot further reported that during the approach to land he made a right turn to final and the engine "flamed out". Subsequently, the pilot performed an emergency autorotation which resulted in abnormal ground contact and main rotor contact with the tail boom. After the landing, the passenger examined the helicopter and revealed that the tail boom sustained substantial damage. The pilot reported that prior to the loss of engine power, there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. The loss of engine power reported by the pilot was likely the result of fuel starvation during the right turn to final. The pilot reported that the fuel level was not checked after the accident.
