Category:Accident
Location:near Högheden airport, Älvsbyn -   Sweden
Phase: Initial climb
Nature:
Departure airport:Älvsbyn Airfield (ESUV)
Destination airport:
Investigating agency: SHK Sweden
Narrative:
The aircraft crashed shortly after takeoff on a hill near Highness Sports Airfield. The crew member was killed and the other seriously injured. The helicopter's mission was to do a video power line inspection in the south of Älvsbyn for the Vattenfall company.

Causes
The accident was caused by an engine failure in flight where the possibilities for a safe emergency landing were limited by the low speed and altitude in combination with a heavily loaded helicopter.

The cause of the engine failure was that the pipe nut backed off and the pipe came loose resulting in a loss of engine power. The nut could back off due to the methods of securing the engine fittings with prescribed torque and the visual slippage inspections before flight was flawed.
