The helicopter was assisting in construction work on a high tension power line. Lost control from low altitude and crashed. Pilot and worker injured and brought to hospital. The main rotor touched one of the high tension masts. The emergency landing took place on sloping terrain and was very hard. The pilot and passenger were seriously injured. The helicopter was damaged.
The helicopter was based at Nordlandsfly's base in Mosjøen. It was involved in another incident on Tovenfjellet (Toven mountain) in 2009 where the helicopter touched permanent snow but didn't crash.
Safety recommendation SL no. 2013/06T
The accident with LN-ODD has shown that the main rotor collided with the traverse on the mast and resulted to the accident. The collision would have been avoided if the flight had been flown with greater safety margins between the structure and the helicopter. Report Safety Studie On-shore Helicopter "Sikkerhetsstudie innlands helikopter" states that collisions with structures have caused many accidents. It does not exist any specific requirements or industrial standard to such a minimum safety margin.
Accident Investigation Board Norway (AIBN) recommends Norwegian Civil Aviation Authority (NCAA), through its leadership in Flight Safety Forum for Operators of On-shore Helicopters "Flysikkerhetsforum for operatører av innlandshelikoptre (FSF)", to establish an industrial standard regarding minimum safety distance between structures and helicopters during flight and announces this to the customers.
