The student pilot stated that the purpose of the flight was for him to perform touch-and-go takeoffs and landings flying solo. After a normal takeoff, he configured the airplane on the final approach leg of the traffic pattern with the engine operating at 1,700 rpm and a descent rate of approximately 500 ft/min descent while maintaining an airspeed of about 75 kt airspeed. He noticed the precision approach position indicator (PAPI) lights showed 3 white and 1 red (indicating he was slightly high on the approach path), and in response, maneuvered the airplane in a more nose-up attitude. As he proceeded on the final approach path, the fuselage collided with powerlines that were oriented perpendicular to the runway and about 300 ft from the threshold. The nose dropped and the pilot attempted to flare. The main landing gear touched down short of the runway threshold and then the nose gear settled into soft mud. The airplane nosed-over, coming to rest inverted. During the accident sequence, the airplane sustained substantial damage to the vertical stabilizer and rudder. The pilot reported that there were no pre impact mechanical malfunctions of failures that would have precluded normal operation.
