A wind farm has been shut down and popular public footpaths cordoned off after a huge chunk of debris flew off a turbine and crash to the ground near Barnsley.
A loud bang was heard on Friday afternoon when parts of the turbine crashed on the nearby path.
Parish councillor Kevin Osbourne, who has called for a safety investigation, said it was lucky no-one was hurt after the failure at Park Spring Wind Farm near Little Houghton.
He said the path was popular with dog walkers and near to the ASOS warehouse, one of the biggest employers in the region.
The path, and others nearby, have now been closed to the public and all three turbines put out of action until operators EDF Energy find out what went wrong.
Cllr Osbourne, who wrote to EDF to demand a “full and thorough” safety investigation, said: “I am seeking safety assurance as the turbine is only six years old. This shouldn’t be happening.
“It wasn’t that windy, it was a blustery day. Debris is still hanging from the blade.”
In his letter to EDF, Cllr Osbourne wrote: “Given the Park Spring Wind Farm’s location close to popular public footpaths, a major road and large distribution warehouse, may I ask you also publicly share the reasons for this blade failure, coming as it did only six years into the working life of the wind farm.
“I would also ask that a full and thorough safety examination of the remaining two towers on the Park Spring Wind Farm be performed immediately to identify any similar faults.”
Piero Maggio, director of asset operations at EDF Energy said: “We are working closely with the manufacturer of the turbine, GE Renewable Energy, to look into exactly what has happened to the damaged machine at Park Spring.
“Already we have stopped the remaining two machines from operating until we know more.
“The damaged machine is cordoned off as are surrounding footpaths and we would like to thank the local community and the ASOS warehouse for their co-operation.
“We will only restart the two other turbines once we are satisfied they have been thoroughly checked and are safe.
“We would be happy to speak to the local councillor about his concerns.”
