Probable cause

The pilot's failure to maintain adequate airspeed while maneuvering to land, resulting in an aerodynamic stall. Contributing to the accident was the pilot's diverted attention while attempting to extend the landing gear.

NTSB narrative

According to multiple witnesses, the pilot was unable to extend the left main landing gear after departure and conducted a series of low approaches over the runway while talking via radio to people located on the ground. After conducting six passes over the runway, the pilot was able to extend the left main landing gear about two-thirds of the way down. The pilot continued to circle the airport within the traffic pattern as the witnesses located on the ground advised him to "slip the airplane to the left then right." Witnesses reported that while the airplane was on downwind for the runway at an altitude of about 400-500 feet above ground level, the airplane "appeared to enter a slip" followed by an immediate roll to the right into a nose-low attitude, and then descended into terrain. Examination of the airframe and engine by a Federal Aviation Administration inspector revealed no preimpact anomalies that would have precluded normal operation. The reason for the left main landing gear not extending was undetermined.
