NTSB narrative

According to the pilot, he was flying a 400-nautical-mile, cross-county flight. He reported that the outside air temperature along the route had been hot. He recalled that the engine temperature had been high and that he "increased the mixture to cool the engine down multiple times." As he approached his destination, the engine began "coughing for 3-4 minutes" before the engine stopped. He attempted to land at the destination airport but was unable to reach it, so he made a forced landing in a mud-filled drainage channel about .5 mile north of the airport.

The airplane sustained substantial damage to the lower fuselage and windscreen.

A Federal Aviation Administration aviation safety inspector examined the airplane's fuel system at the accident site. He reported that both fuel tanks were found empty, with about 1/2 cup of fuel at the bottom of the left tank, after removing the sump drain.

Per the National Transportation Safety Board's Pilot Aircraft Accident Report, the pilot reported that the accident could have been prevented with the "Use of [a] fuel dipstick for better measurement of fuel quantity."

The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Probable cause

The pilot’s improper preflight fuel planning, which resulted in a loss of engine power due to fuel exhaustion.

  • 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: local date, investigation status, coordinates. Values present in the bulk record are kept.
