Authorities say a pilot from Illinois escaped injury when his light plane developed engine trouble and he had to make an emergency landing in a corn field in southwestern Wisconsin.

The Kenosha County Sherriff's Department says the single-engine Cessna 172 was en route to Chicago Executive Airport in Wheeling, Illinois, from Burlington Municipal Airport in Wisconsin when the engine trouble developed around 3 p.m. Tuesday. The pilot tried to land at Wetosha Airport but couldn't make it and had to land in the field in the Town of Randall instead.

The pilot, a 72-year-old man from Grayslake, Illinois, was not injured. His name has not been released. The plane, which was built in 1969, sustained moderate damage and caused some crop damage.

The Federal Aviation Administration will investigate.
