The pilot reported that he elected to conduct a low approach over the private airstrip to familiarize himself with the area. He approached the airstrip from the north and entered a left base. After turning final, the airplane was on a stabilized approach. About 20 ft above the airstrip he applied full power, pitched the nose up, and retracted the flaps. The airplane would not gain altitude and the uphill elevation of the airstrip was quickly rising. The airplane narrowly cleared the hill at the end of the airstrip, but continued to lose altitude. The airplane touched down, went over an embankment and nosed over, coming to rest inverted. The airplane's fuselage and wings were substantially damaged. The pilot reported that there were no mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
