The Air Accident Investigation Board of Norway (AIBN) has published a preliminary report on the accident at Turøy, near Bergen, Norway on 29 April 2016.
An Airbus H225 helicopter was en route from an offshore platform in the Norwegian sector to Bergen Airport Flesland. The helicopter was cruising at 600m when the Main Rotor Head (MRH) and mast suddenly detached. The helicopter impacted on a small island and caught fire. The main wreckage thereafter ended in the sea where it came to rest at a depth of 1-9 meters. 11 passengers and two crew perished in the accident.
