Pilot Account
The pilot stated that the fuel tanks were topped off the day before departing El Monte, California. He estimated that the aircraft had 534 pounds of fuel on board and consumed 80 pounds per hour during cruise at 9,500 feet mean sea level. According to the pilot's operating manual, the aircraft had an endurance of 6.7 hours with no reserve.
Fuel Management During Flight
During the flight, the pilot switched tanks at one-quarter tank intervals. When he was approximately 40 miles from his destination, the left tank was exhausted. He selected the right tank and observed an indication that it was still one-quarter full.
Engine Power Loss and Landing
While on final approach to the Driggs Municipal Airport, the engine lost power. The pilot executed a forced landing in a field. During the landing, the nose wheel encountered a sharp hole and failed, and the aircraft subsequently went over on its top.
Post-Accident Examination
An on-scene examination found no fuel in either fuel tank.
