As the nose gear settled to the runway, "the left main gear hit a patch of snow or mud and grabbed." Right rudder and aileron control inputs were applied in an attempt to maintain directional control. The right main landing gear "hit some snow" and the airplane tipped up on its left wingtip and propeller spinner before nosing over.
