On April 29, 2016 at 11:54 AM, a helicopter carrying oil workers from the Gullfaks B oil field off the coast of Norway crash landed on Turøy outside Bergen. Moments earlier, several witnesses reported the helicopter as flying steadily and normal, before losing its rotor and losing altitude, and subsequently crash landing.[1]
While initial reports stated that some of the passengers had survived, it was later confirmed that the crew and passengers were all presumed killed in the crash.[2]
Chronology of events
Prior to the crash
At 10:05 AM local time (GMT+1), HKS241 took off from Flesland Airport, five minutes behind schedule. It arrived at the Gullfaks B oil field on time, and departed from the rig at 11:16 AM local time, carrying two pilots and eleven passengers. It was schedueled to land at Flesland Airport at 12:08 PM.
The crash
At 11:53 AM, as the helicopter approached Sotra off the coast of Bergen, several witnesses observed the flight, stating that nothing was out of the ordinary. Just moments later, the main rotor of the helicopter detached, causing a sudden drop in speed and altitude, as confirmed by flight telemetry. Failing to regain control of the craft, it crashed on the small island of Turøy at 11:54:35 AM local time and exploded on impact.[3] According to flight data, the time passed from the detachment of the rotor to the crash itself was only eleven seconds, with a dive of 640 m (2100 ft) during the same time span.[4][5]
Response
At 11:55 AM, local police received reports of a helicopter crash. Six minutes later, at 12:01 PM, this is relayed to the national rescue service. Rescue workers, police and fire fighters arrived at the scene at 12:20 PM, and the wreckage was located partially submerged soon after. At 1:15 PM, authorities confirmed that the wreckage had been found, and that they did not expect to find survivors.[6]
At 1:46 PM, less than two hours after the crash, all similar helicopters on Norwegian soil were temporarily grounded until further notice. This was later expanded to a complete restriction and grounding by Norwegian aviation authorities.[7] Later that day the Civil Aviation Authority issued a Safety Directive which grounded all Super Puma helicopters on the United Kingdom Civil Aircraft Register, or flying in United Kingdom airspace, except for aircraft being used for Search and Rescue purposes.[8][9]
Crew and passengers
During its final flight, the aircraft was carrying eleven passengers and two pilots. Authorities have confirmed that those on board were all Norwegian, except for one British and one Italian passenger. No names have been released.
Investigation
The Norwegian Accident Investigation Board (AIBN) is responsible for investigating aviation accidents in Norway.[10]
