Before the accident flight, the pilot purchased 30 gallons of aviation gasoline, following which the fuel gauges indicated near half for each tank. During the accident flight, the pilot flew about 12 minutes south of the departure airport with the left fuel tank selected then turned north to return to the airport. About 5 minutes after turning north, the engine went to idle power. The pilot turned the carburetor heat on and activated the boost pump, and the engine returned to normal cruise power. The pilot indicated that, at this point, she should have switched the fuel selector valve to the right fuel tank but did not. The engine operated at cruise power for about 1 minute then quit completely. The pilot reported that because the airplane was about 1,500 feet above ground level and changing the fuel selector valve requires moving the pilot seat back about 18 inches “with no control of the aircraft,” she decided to perform a forced landing on a farm road directly ahead. During the landing, the right wing struck a fence post, and the airplane subsequently came to rest in a plowed field. Both wings sustained substantial damage. The pilot reported that the accident was caused by fuel starvation and that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
The pilot purchased 30 gallons of aviation gasoline (AVGAS) prior to a local flight. The purchased AVGAS was divided between the left and right fuel tanks. The fuel tanks showed a little over one-half on the right and a little less than one-half on the left. The pilot flew about two tenths of an hour south and then turned north back to the airport. About five minutes after turning north, the engine went to idle. The pilot pulled the carb heat on, activated the boost pump, and the engine returned to normal cruise power. The pilot indicated, "At this point I should have switch to the right tank." The engine ran about one minute then quit completely. The airplane was about 1,500 feet above ground level. The pilot reported that "the changing of the fuel select valve requires the pilot to move the seat back about 18 in[ches] with no control of the aircraft, I thought a controlled forced landing better than an uncontrolled one." The pilot reported that the accident was caused by fuel starvation and that there were no preaccident mechanical failures or malfunctions of the airplane.
The pilot’s improper fuel management, which resulted in a loss of engine power during cruise flight due to fuel starvation.
