At least two attempts to land had failed as the aircraft approached too high in minimum ceiling conditions. The pilot tried to maneuver the aircraft to another runway at a low altitude. The wing struck the ground and the DC-4 skidded for 700 feet. The aircraft was named "Mainliner Lake Michigan".
PROBABLE CAUSE: "The Board determines that the probable cause of this accident was a loss of altitude during a turn preparatory to a final approach while the pilot was manoeuvring in an attempt to land."
