No sign of engine failure in North Sea helicopter crash
2:45pm Thursday 5th September 2013 in News
AN investigation into a North Sea helicopter crash which killed four oil workers, including two from the North-East, has so far found no evidence of technical failure.
Three men and a woman died when a Super Puma plunged into the sea off Shetland on August 23. There were 14 survivors.
To date, no evidence of a causal technical failure has been identified; however, detailed examination of the CVFDR (combined voice and flight data recorder) data and the helicopter wreckage is continuing, the Air Accidents Investigation Branch said in a report.
Duncan Munro, 46, a welder from Coundon, near Bishop Auckland, was on the Super Puma L2 aircraft which went down about two miles west of Sumburgh airport as it was returning to Shetland from the Borgsten Dolphin platform.
A second North-East man, George Allison, 57, formerly of Washington, Wearside, but who was living in Winchester, in Hampshire, at the time of the accident, was also killed, along with Sarah Darnley, 45, from Elgin, and Gary McCrossan, 59, from Inverness.
The AAIB said that both the helicopter's engines were giving out power when the aircraft hit the water.
It said that data downloaded from the black box on Sunday showed that the flight approach of the Super Puma was normal until three miles from the airport. At two miles it was below its correct path.
The report said: "The rate of descent remained constant for a period, before increasing rapidly.
"Shortly thereafter the helicopter, which was intact, struck the sea in a near level pitch attitude with a slight right bank.
"Both engines were delivering power until impact."
