The pilot of the tailwheel-equipped airplane was on a personal flight to the accident airport. Upon arrival at the airport, the reported wind from ASOS (Automated Surface Observing Systems) was 330 degrees at 5 knots. He entered a left downwind for runway 31 and had planned to do a wheel touch-and-go landing. The pilot stated that he was slower than intended and over the runway threshold he added power to maintain a wheel landing attitude. He failed to add enough power to fully arrest the descent and had to increase back pressure pitch input to stabilize the descent. The pilot stated that after touchdown the airplane had a slight nose left attitude and began to turn to the left. He corrected with right rudder and added more power to keep a nose-level attitude but was not able to fully correct the left turn. The pilot then applied full power to go around, but the airplane was already too slow to take off and the airplane departed the runway. He reduced all power and attempted to brake but the airplane struck a berm and nosed over coming to rest inverted about 30 ft from the runway edge. The airplane sustained substantial damage to the wings, fuselage, and tail. The pilot reported there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
