Amateur-built CP328 SUPER EMERAUDE accident near Port Wing, Wisconsin, September 5, 2015
On September 5, 2015 at about 3:15 pm local time, a 1993 amateur-built CP328 SUPER EMERAUDE, registered N328TV, was substantially damaged in an accident during landing near Port Wing, Wisconsin. It was a personal flight under general aviation rules (Part 91). 1 person had minor injuries. The weather was visual conditions (good weather).
The NTSB's probable cause their words, unchanged
The pilot’s undershooting the landing area and the subsequent impact with a hay bale. Also causal to the accident was the operation of the airplane in conditions conducive to carburetor icing, which reduced the engine power during the landing.

The NTSB's narrative final · quoted from the NTSB record
The pilot reported that she had flown the airplane locally to reduce fuel weight and was on approach to land on a hay field. During the approach, the pilot turned on the carburetor heat and the fuel boost pump. The pilot reported that, after she turned the airplane onto the final approach, she thought that it was a little low, so she applied engine power to reach the airstrip. She further stated that, although the engine continued to run, there was a lack of engine power. The pilot pulled back slightly on the flight controls to avoid a hay bale, but the airplane's tail struck the bale. The airplane flipped over and came to rest inverted. The pilot reported that there were no mechanical malfunctions with the airplane. Weather conditions at the time of the accident were conducive to the formation of serious carburetor icing at glide power. Given the weather conditions, it is likely that the carburetor accumulated ice during the short approach but that insufficient time existed for the carburetor heat to melt the ice, which led to the reduction of engine power.
