Super Puma crash investigation Norway

On 29 April 2016, a CHC Helikopter Service Eurocopter EC225 Super Puma helicopter, carrying oil workers from the Gullfaks B platform in the North Sea, crashed near Turøy, a Norwegian coastal island 36 kilometres (22 mi) from the city of Bergen. Several witnesses reported initially seeing nothing untoward with the helicopter flying steadily, before the sound suddenly changed and it started to sway. A moment later its main rotor assembly detached from the aircraft and the fuselage plummeted to the ground and exploded into flames. All 13 crew and passengers died in the crash.
