Investigating agency: NTSB
Narrative:
The main rotor blades struck and severed the tailboom of the helicopter during a hard landing following a loss of engine power. The helicopter departed the airport to the southwest and climbed to 400 feet AGL. The pilot turned the helicopter downwind and leveled the aircraft. He set 'cruise power' and the engine 'spooled down.' The pilot performed an autorotation to a muddy, grassy field and landed hard. The engine was test run and it was determined that the fuel scheduling was incorrect as the turbine outlet temperature would exceed the maximum allowed. After replacement of the fuel control unit, the engine was 'found to meet new engine performance at all guarantee test points.' The fuel control unit was functionally tested and operated within service limits. The reason for the loss of engine power could not be determined.
Probable Cause: The improper flare during an autorotation by the pilot-in-command. A factor was the loss of engine power for an undetermined reason.
