First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary

NTSB narrative

During a cross-country flight, about 1 hour 20 minutes after takeoff, the airplane's engine lost power. The pilot reported that 'an attempt to flare for landing resulted in loss of airspeed rather quickly and the aircraft dropped from a near stall condition hitting the ground flat and hard.' Examination of the fuel system revealed no usable fuel in the fuel tank. Examination of the accident site revealed no evidence of fuel spillage. The pilot rated passenger had just purchased the homebuilt Skybolt TD8 experimental airplane, and it was being flown to Ohio. The airplane's fuel tank was topped off prior to departure. The planned time en route was 1 hour 30 minutes. The builder of the airplane reported that the capacity of the airplane's fuel tank was 29 gallons; however, the airplane's fuel tank capacity was measured at 22 gallons. According to the builder, the average fuel consumption for this airplane is 20 gallons per hour. The commercial pilot reported to the NTSB that this accident could have been prevented by a 'more thorough examination and verification of all phases of aircraft. Actual fuel capacity - consumption - etc. Don't make assumptions of the other persons work.'

Probable cause

Hard landing due to the pilot's improper landing flare. Factor were the fuel exhaustion due to the pilot's failure to refuel, and his lack of familiarity with the airplane.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
