NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
The airplane collided with terrain while maneuvering in the base to final turn for landing. According to a witness, the airplane approached from the north and circled the airport in a counterclockwise orbit. It turned south (left) after crossing the departure end of runway 28, and flew parallel to the south side of the runway. During this turn, the landing gear came down. A witness observed it turn left base for landing. Throughout this sequence the engines sounded steady and smooth. It remained in the left turn, and then appeared to cross the extended centerline of the runway. Then the left turn increased sharply so that the wings were about 90 degrees to the horizon. The nose of the airplane then dropped abruptly to a nearly vertical position. The witness heard the engines sounds change like they were popping or stalling. The airplane maintained the nose low attitude until it hit the ground and burst into flames. Post accident examination did not reveal any evidence of engine malfunction or anomalies with the control system. Three of the four propeller blades exhibited chordwise striations; fire consumed the outboard portion of the remaining blade. The pilot did not hold a multiengine rating and had owned the airplane since 1978.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the failure of the pilot to maintain an adequate airspeed resulting in a stall and loss of control. Full narrative available
