Radar data depicted an airplane flying a track similar to a right traffic pattern for the runway. While on a track consistent with a right base leg, the airplane entered a left turn. About the same time as the accident, witnesses reported seeing an airplane fly a right base leg for the runway. The airplane entered a steep left bank, followed by an abrupt descent angle, and collision with terrain. A review of recorded radio transmissions revealed the pilot of the accident airplane flew a right hand pattern for the runway. The pilot queried a pilot of another airplane of his intentions. At that time, the other airplane was ahead of the accident airplane, on a final approach leg. The accident airplane then entered the left turn. A radar study indicated that while in the left turn, the approximate airspeed of the accident airplane was approaching or below the stall speed for the make and model airplane.
Probable Cause: The pilot-in-command's failure to maintain adequate airspeed while maneuvering in the traffic pattern, which resulted in an inadvertent stall/spin.
