Narrative:
The helicopter flew transport missions for the Norwegian Armed Forces when it crashed at Hjerkinn in Dovre. AIBN investigation confirms the pilot in command's statement that the engine stopped shortly after the departure. One of the five occupants was seriously injured when the helicopter hit the ground. The helicopter was substantially damaged.
AIBN investigations indicate that engine power was lost due to blockage of fuel supply to the engine.
It has not been possible to find a clear explanation of what caused this blockage.
AIBN has found that warning-logic in the helicopter did not provide the pilot in command with the appropriate information according to the severity of the onset error. In this connection, the Accident Investigation Board Norway has issued a safety recommendation to the helicopter and engine manufacturer.
