The National Transportation Safety Board is releasing preliminary information in its investigation of a Tuesday night plane crash in Sauk County that left six people dead.
Five adults and one child were killed when the aircraft went down in the Town of Dellona.
Investigators say the plane was at 24,000 feet when the pilot radioed that they were experiencing icing and requested to descend.
Communication and data were lost shortly after.
The flight out of Kenosha had been bound for Menomonie, Wisocnsin.
