Analysis

The aircraft experienced fuel exhaustion during cruise about two miles from the intended destination airport. The pilot landed on a high school football field and was unable to stop prior to colliding with a fence. The pilot said that he had 'never been able to completely trust the fuel quantity indicators,' and, that visual checks of the fuel tanks were not accurate due to the ground attitude of the aircraft. The pilot noted that he used a system of fuel usage calculation versus amount of fuel loaded onboard to determine the amount of fuel in the tanks at any given time. The pilot stated that he had not used a fuel dip stick device to quantify the amount of fuel in the tanks.
