The pilot was making an approach to landing in day visual meteorological conditions. On the final leg of the traffic pattern, the pilot descended too low and impacted trees prior to the runway. The airplane sustained substantial damage to the fuselage and wings. Neither the pilot nor a Federal Aviation Administration inspector, who examined the airplane after the accident, reported any preexisting malfunctions or mechanical anomalies. The nearest weather reporting facility, located approximately 16 nautical miles east of the accident location, reported calm winds, 10 statute miles visibility, and few clouds at 1,100 feet at the time of the accident.
