Analysis

Since the fuel gages in the acft were known not to be accurate, the plt measured the amount of fuel in each tank with a dipstick before departing. He determined that he had 18 gallons for the 2 hours of flying he planned to do and based on a fuel consumption rate of 5 gph he would have 8 gallons to spare. The acft ran out of fuel short of his destination and nosed over in a field during the ensuing landing. Using a Cessna aircraft performance chart that was in the acft, the consumption rate for the engine running at 75% power at 2500 feet MSL was 8.5 gph. The 8.5 gph does not take into account the fuel required for eng start, taxi and climb.
