Narrative:
THE NON-INSTRUMENT RATED PILOT GOT A WX BRIEFING AT ABOUT 1600 CST FROM THE MINNESOTA WX ADVISORY SERVICE & DEPARTED MANKATO ON A FLIGHT TO ROCHESTER.

FACTORS RELATED TO THE ACCIDENT WERE: AN INACCURATE WEATHER FORECAST BY THE NATIONAL WEATHER SERVICE, OPERATION OF THE AIRCRAFT BY THE PILOT WITH A KNOWN DEFICIENCY IN EQUIPMENT (RADIO), DARKNESS, THE ADVERSE WEATHER CONDITIONS, THE PILOT'S PROBABLE SPATIAL DISORIENTATION, AND HIS LACK OF INSTRUMENT EXPERIENCE.
