Part of a wind turbine under construction broke apart Saturday morning.
The problem started Friday when construction crews were installing a second wind turbine for Waverly Light and Power.
During the process, a construction error caused the rotor and blades to start moving in the wind prematurely - spinning uncontrollably and unable to stop until it broke.
An unexpected problem has occurred with construction of second wind turbine

The construction company, ICS of North Dakota, lifted the wind turbine rotor assembly, to which the blades attach, 246 feet high into place late yesterday afternoon. After it was lifted it was discovered the blades were not ‘feathered' or turned properly so they could not catch the wind. In the position the blades are in, the wind caught the blades causing them to spin.
When this was discovered, the Bremer county sheriff's department was notified and all personnel were evacuated, including two homeowners who were outside of the recommended danger zone.
Bill Fish wants the Municipality of Chatham-Kent to investigate homemade windmills after his neighbour's device came crashing through his roof during yesterday's high winds.
He was shocked awake around 3 a.m. when an eight-foot-long wooden blade penetrated the roof, before piercing through the ceiling and wall in a sewing room of his Dufferin Avenue home, located outside of Wallaceburg in Chatham Township.

Three wind turbines at Perkins High School crashed Saturday when the blades broke off one of them.
No one was hurt when parts of the fiberglass blades came off the turbine as it spun, winging the blades up to 40 yards away from the silver monopole tower, near the high school at 3714 Campbell St.
The remaining two turbines will not be used until they are inspected and officials figure out what caused the blades to break.

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. ..."The bolt failure was the effect not the cause of the problem. They have ruled out bolt fatigue and design problems, and we know that they were properly put on," said Dale Vince the co-founder of Ecotricity, which owns the farm.
