A 65 ft blade that flew off the turbine came loose after bolts attaching it to the hub failed, not because of a collision, examination of the components has revealed.
...after weeks of analysis the turbine manufacturer Enercon has released an interim report identifying material fatigue as the cause of the accident.
They are now carrying out further tests to establish what caused the bolts to come loose, focusing on the blade and hub components to which they were attached. If one of these failed, the bolts could have been put under unbearable stress.
Fraser McLachlan of GCube, which insures more than 25,000 wind turbines, said at the time that a simple mechanical failure was the most likely explanation. "You get three or four cases of things like this a year. They are machines and machines are going to break," he said.
