On 29 April 2016 a CHC Helikopter Service Eurocopter EC225 Super Puma (H225) 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 its main rotor detached and it plummeted to the ground and exploded into flames.[1]
All thirteen crew and passengers on board died in the crash.[2]
Aircraft
The accident aircraft was a Eurocopter 225LP Super Puma helicopter, manufactured by Airbus Helicopters, registration LN-OJF.[3].
Background
At 10:05 a.m. local time (UTC+2), HKS241 took off from Bergen's Flesland Airport, five minutes behind schedule. It arrived at the Gullfaks B platform on time and departed at 11:16 a.m., carrying two pilots and eleven passengers, employees and subcontractors of Norwegian oil company Statoil.[4] It was scheduled to land back at Flesland Airport at 12:08 p.m.[1]
Crash
At 11:53 a.m., 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. With all control lost, it crashed on the islet of Skitholmen between the islands of Turøy and Toftøy at 11:54:35 a.m. local time and exploded on impact.[5] Most of the wreckage then slid off the islet into the sea. A video recording of the detached rotor spinning to earth was made shortly afterwards.[4] The rotor came to rest several hundred metres away on the island of Toftøy. According to flight tracking data, the time between the detachment of the rotor and the crash itself was only eleven seconds, with the helicopter diving 640 metres (2,100 ft) during that time span.[5]
Response
At 11:55 a.m., local police received reports of a helicopter crash. Six minutes later, at 12:01 p.m., this was relayed to the national rescue service. Rescue workers, police and fire fighters arrived at the scene at 12:20 p.m., and the wreckage was located partially submerged soon after. At 1:15 p.m., authorities confirmed that the wreckage had been found, and that they did not expect to find survivors.[5]
At 1:46 p.m., less than two hours after the crash, all similar helicopters on Norwegian soil were temporarily grounded until further notice,[6] except for aircraft being used for search and rescue purposes.[7] This was later expanded to a complete restriction and grounding by Norwegian aviation authorities.[6] Later that day the British Civil Aviation Authority issued a Safety Directive which grounded all EC 225LP 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] On 30 April, Airbus Helicopters issued a Safety Information Notice expressing their support of the decision to put all commercial passenger flights with Super Puma helicopters of model EC225LP "on hold". Other versions of the Super Puma are not included in this decision.[10]
Norwegian Prime Minister Erna Solberg described the crash as "horrible". King Harald V and Queen Sonja cancelled a visit to Sweden[3] that was to have marked King Carl Gustaf's 70th birthday.
Crew and passengers
During its final flight, the aircraft was carrying eleven passengers and two pilots.[11] Authorities have confirmed that eleven of the people on board were Norwegian, with one British passenger and one Italian crew member. Twelve were men and one was a woman. The eleven passengers were employees of six different companies: Halliburton (4), Aker Solutions (3), Statoil (1), Schlumberger (1), Welltec (1) and no (1).[12][13] One of the Halliburton employees was named as a British national from Laurencekirk in Aberdeenshire.[14]
Investigation
The Norwegian Accident Investigation Board (AIBN) is responsible for investigating aviation accidents in Norway.[15] The British Air Accidents Investigation Branch and French Bureau of Enquiry and Analysis for civil aviation safety (BEA) each dispatched a team of investigators to Norway to assist the AIBN in their investigation. Representatives from Airbus Helicopters and Turbomeca were part of the BEA team.[16][17]
The aircraft's cockpit voice and flight data recorders were sent to the United Kingdom for data retrieval.[18] Data was successfully downloaded on 1 May and sent back to AIBN who confirmed that the received data was of high quality and useful for further investigation.[19]
On 1 May the BBC revealed that the helicopter had been forced to land days before, over fears of a technical problem, when a cockpit warning light had illuminated, a few minutes into a flight to an offshore platform on Tuesday 26 April.[20]
