Accident Overview
During cruise, the pilot transmitted to Air Route Traffic Control Center (ARTCC) that they had a problem and were losing altitude. The controller provided a vector to the nearest airport, but shortly afterward, the pilot stated they would not be able to reach it. The pilot did not specify the nature of the problem beyond reporting a rapid descent. The aircraft subsequently crashed in a wooded area approximately half a mile from an open area.
Investigation Findings
Post-accident examination revealed about one quart of fuel remaining in the left inboard (auxiliary) fuel tank. All other fuel tanks were ruptured from impact, and no evidence of fuel spillage was found at the accident site. The left propeller was found in the feathered position, and the right propeller was partially feathered. No pre-impact part failure or malfunction was identified. Both engines were started and operated satisfactorily after being supplied with fuel from temporary tanks.
Occupants
The pilot and two passengers were killed, while a fourth occupant sustained serious injuries.
Probable Cause
The official probable cause was loss of engine power (total) due to fuel exhaustion, resulting from the pilot's inadequate preflight inspection and inadequate fuel supply management. This led to a forced landing and subsequent collision with trees and terrain.
