NSW pilot alive after engine failure

The pilot of a crop-duster has escaped injury after making an emergency landing when his engine failed in the NSW Hunter region.

The plane was spreading super phosphate when it went down about 11am on Tuesday at a Davis Creek property, near Barrington Tops National Park, east of Muswellbrook.

"He's walked away unscathed, he's very lucky. He's suffered an engine failure and had to land on a really hilly area," Westpac Rescue Helicopter spokesman Glen Ramplin told AAP.
