The airplane was substantially damaged when it impacted a chain link airport perimeter fence and trees during an aborted landing attempt on runway 26 (3,058 feet by 50 feet, asphalt). The pilot stated that when the airplane was on final, he noticed that it was coming in "a little high" so he reduced engine power and "nosed up to reduce speed". The pilot initially "thought there was enough runway" for a full stop landing but realized the airplane had landed long. He decided to abort the landing and added full engine power. Near the end of the runway, the airplane pitched up, porpoised two or three times, and veered to the left of the runway. He reported that the airplane then pitched down and continued down the grassy slope to the left of the runway, where it subsequently impacted the chain link perimeter fence and trees. No mechanical anomalies with the airplane were reported by the pilot. The pilot stated in his accident report that the accident could have been prevented by performing a go-around.
