Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary

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
Total loss of engine power (non-mechanical)
Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
Fuel exhaustion
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

The pilot/mechanic who overhauled the accident airplane engine was to remove it from the airplane, located on a highway in a remote desert area, to correct some discrepancies, which had caused the owner's pilot to make a precautionary landing. The mechanic chose to fly the airplane to another state where his shop is located. En route to a fuel source he landed on a road for directions. Subsequently, he arrived at the fuel source and had less than a gallon remaining. His next planned fuel stop was about 75 miles away. In the pilot's written statement he said he remembered noticing the fuel gauges reading low as he was flying low over sand dunes. The engine lost power, he turned on the boost pump, and the engine regained power momentarily. The aircraft then collided with sand dunes in the Death Valley National Park. The pilot reported that there were no mechanical problems with the airplane and he had run it out of fuel. The accident site is about 195 miles from the departure point on a heading about 90 degrees from the pilot's intended course line.

Probable cause

fuel exhaustion resulting from the pilot becoming lost and disoriented on a cross-country flight.

  • 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.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
