Accident Overview
During the landing roll of a night forced landing, the airplane encountered soft and wet terrain. This caused the nose gear to partially collapse, and the airplane subsequently flipped over.
Fuel Exhaustion
The accident flight experienced a complete loss of engine power due to fuel exhaustion. This occurred on an extended downwind leg following a two-leg cross-country flight that had a total duration of 2.9 hours.
Forced Landing
The second pilot executed the night forced landing because he had accumulated more total flight time than the pilot-in-command (PIC).
Investigation Findings
The investigation revealed that the rental airplane had flown one flight of 0.7 hours before departing on the accident trip and had not been refueled upon its return. The PIC had based her fuel consumption calculations on a rate of 4.6 gallons per hour (GPH), whereas records indicated that the correct consumption rate was 6.4 GPH.
