Analysis

According to the pilot, the powered glider bounced on landing. After the glider bounced a second time he decided to abort the landing and perform a go-around. He applied full engine power, but attempted too steep of a climb and stalled one wing which turned the glider toward some trees at the side of the runway. The glider failed to clear the trees substantially damaging the empennage, both wings and the propeller. The pilot further stated that there were no mechanical problems before the accident.
