The pilot reported that on the morning of the flight he used a fuel dipstick to check fuel tank quantities prior to his flight. The fuel tank dipstick was marked in the number of skydiving flights and reserve fuel had a mark as well. The right tank showed a higher fuel quantity than the left and when combined, the stick showed enough fuel for three flight loads of jumpers. He further stated that he fueled the airplane up to the “four load” level five days prior to the accident flight, which was the last time the airplane was flown.
