NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The airplane departed on the accident flight, and after flying 1 hour 18 minutes using fuel from the left tank, the pilot switched fuel tanks, and the engine lost power. (A passenger reported that there was a strong headwind, so the pilot was diverting for fuel.) Attempts to restore power were unsuccessful. During the ensuing forced landing, the airplane's right wing collided with a tree before the airplane impacted terrain.
The pilot said that, before departure on the accident flight, he had 20 gallons of fuel in each wing fuel tank. However, postaccident examination revealed no fuel in the uncompromised left wing fuel tank. The right wing fuel tank had been compromised, but there were no fuel stains on the ground and there was no odor of fuel in the immediate area. Later, the engine was functionally tested and operated satisfactorily at all power settings. Thus, the airplane likely departed with minimal fuel available in the right wing fuel tank; when the pilot selected the right tank during cruise flight, the engine likely lost power due to fuel exhaustion.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's inadequate preflight inspection and planning and inflight fuel management, which resulted in a loss of engine power due to fuel exhaustion and a subsequent forced landing in an area of unsuitable terrain.
