An Australian company that wants to buy a Cambria County wind farm might walk away if it's not determined what caused seven turbine blades to crack and large pieces of two blades to fly off.

The problems at the Allegheny Ridge wind farm are a serious concern, said Neal Emmerton, regional asset manager for Sydney-based Babcock & Brown. Gamesa, the Spanish firm that developed the facility, has been paid, but the deal won't be final until the blade issues are resolved, he said.
