On September 29 the Norwegian oil company Statoil issued the report on its investigation into the April 29 fatal crash of a CHC Airbus Helicopters EC225LP. The helicopter was transporting 11 of its personnel from the Gulfaks B offshore platform in the Norwegian continental shelf (NCS) to Flesland. It crashed en route after the main rotor assembly separated from the aircraft in flight, near the small island of Turoy, west of Bergen, killing the passengers and the two pilots aboard and prompting a worldwide grounding of the fleet in June. The ban was lifted by the EASA earlier this month, but it remains in force in the UK and Norway. Investigators for the Norwegian Accident Investigation Board (AIBN) have yet to formally determine the cause of the crash, but the EASA has cleared the helicopter for return to service following replacement of a main gearbox planet gear and a heightened inspection regime.
