A Mississippi Valley Airways, Inc., DeHavilland DHC-6, N956SM, crashed at La Crosse, Wisconsin, on November 9, 1970, at approximately 1608 central standard time while executing a nonprecision instrument approach in instrument flight conditions. The aircraft struck trees approximately 4,000 feet from the threshold of Runway 13 on approach centerline. The aircraft was destroyed by impact. The captain, first officer, and three of the four passengers sustained serious injuries. There was no post-crash fire. The National Transportation Safety Board determines that the probable cause of this accident was that for reasons unknown, the captain failed to maintain altitude at minimum descent altitude and allowed the aircraft to descend below the height of trees while executing a nonprecision instrument approach in instrument flight conditions.
