MINNEAPOLIS — A federal report said the pilot of a plane that crashed in central Minnesota wasn’t equipped or trained to fly in low clouds.

Stuart Dahlberg, his wife Ivelisse Morillo, and his mother, Mae Dahlberg died when their single-engine Beechcraft Bonanza went down in a farm field near Glencoe in March.

A National Transportation Safety Board report said the plane did not have the instruments necessary to fly without normal visibility. It also said pilot Stuart Dahlberg of Brooklyn Center was not certified to fly by instruments when he flew into low clouds before his plane crashed.

He lost control of the plane and it broke apart in midair. It left a 900-foot-long swath of debris across two fields.
