Narrative:
The airplane suffered a partial loss of engine power. The pilot conducted a forced landing; however, impacted trees and the terrain during the descent. The pilot told a physician that the airplane suffered a loss of about 70% power and later told his attorney that the airplane suffered fuel exhaustion. An examination of the airplane subsequent to the accident revealed no mechanical anomalies other than those associated with impact. Emergency responders and Federal Aviation Administration inspectors were on site within two hours of the accident. They did not find any fuel leaking from the airplane and did not smell fuel. An examination of the left fuel tank found only unusable fuel. The fuel selector was found positioned to the left fuel tank.

Probable Cause: the pilots improper preflight planning, which failed to detect the fuel selector positioned on the left fuel tank, which had insufficient fuel, resulting in fuel starvation, and the loss of engine power.
