NTSB Narrative Summary Released at Completion of Accident
When the pilot was about fifty miles from the destination airport, with the fuel gauge indicating about 20 gallons of fuel remaining, the experimental airplane's engine lost all power. The pilot ultimately made a power-off forced landing in open terrain, and the airplane nosed over when its nose gear dug into the soft terrain. The investigation determined that there was no evidence of any fuel in the airplane's fuel system, and no evidence of fuel spillage or leakage at the scene. There also was no evidence of stains on the airplane consistent with in-flight fuel system leakage. A post-accident inspection of the airplane and its fuel system found no anomalies or evidence of leakage. The pilot, who had planned his flight using the "recommended power settings for cruise flight" of eight to nine gallons per hour, did not take into account the fuel burn for his initial climb of over 11,000 feet. In addition to that climb, the pilot had to climb back to 11,500 feet mean sea level (msl) after twice descending to lower altitudes in order to maintain visual meteorological conditions (once to 9,500 feet msl, and once to 7,500 feet msl). In the section of the NTSB form 6120.1/2 where the operator/owner was provided the opportunity to indicate how this accident could have been prevented, the pilot stated, "Installation of Fuel Burn Rate instrumentation."
NTSB Probable Cause Narrative
Fuel exhaustion due to the pilot's inaccurate fuel consumption calculations. Factors include an inaccurate fuel quantity measuring system, and soft terrain encountered during the landing roll.
