Preliminary data based on the notification from the Belgian authorities:
The pilot owner wanted to bring 3 friends for a lunch in Valenciennes (France). He took his helicopter out of the hangar, located off EBKT airport, landside. After preflight, the helicopter took off and hovered at 15m above the hangar. The pilot felt a couple of yaw movement of the helicopter, noticed a red warning light (low rotor rpm). He decided to land the helicopter in autorotation on the grass area. The helicopter landed very hard in front of the airport perimeter fence. One blade of the main rotor hit one of the fence poles and sent it 50m away. The occupants climbed out of the helicopter, helped by the fire brigade.
