At the time the airplane was flying at about 110 mph. The pilot made a force landing in a field with power lines and fences. During the landing roll, the airplane impacted a fence. The airplane then traveled down an embankment and flipped over before coming to a stop. The pilot stated there were no mechanical failures or malfunctions to the airplane or any of its systems prior to the accident.
