Probable cause

Inadequate preflight by the pilot and his misjudgement of the fuel supply, which resulted in fuel exhaustion. The ditch was a related factor.

Analysis

The airline transport rated pilot had waited over 1 hour for fuel and decided he had enough fuel to get from towanda, PA to seamans airport, PA, so he did not refuel. Subsequently, the engine lost power and the aircraft was landed in a field 1-1/2 to 2 miles from the destination airport. During landing, the aircraft hit a ditch & flipped overon its back. An on-site investigation revealed no fuel was remaining.
