NTSB narrative

THE STU PILOT WAS EN ROUTE WHEN SHE RADIOED THE ENGINE WAS LOSING POWER. ACCORDING TO ANOTHER PLT, THE STU PLT SOUNDED PANIC-STRIKEN DURING THE TRANSMISSION. THE ACFT CRASHED INTO A SMALL POND, SURROUNDED BY AN OPEN FIELD. DAMAGE TO THE ACFT, INDICATED THE ACFT STRUCK THE POND IN A STEEP NOSE DOWN ATTITUDE. EXAMINATION OF THE ACFT DID NOT REVEAL EVIDENCE OF MECHANICAL MALFUNCTION. INSPECTION OF THE LEFT WING SURFACE BEHIND THE FUEL TANK FILLER NECK, INDICATED THE FUEL CAP WAS UNFASTENED AND LAYING ON THE WING INFLIGHT. A FLIGHT TEST IN A SIMILAR ACFT WITH AN UNFASTENED LEFT FUEL CAP REVEALED THE CAP MOVED AFT AND WAS HELD BY ITS CHAIN. DURING THE TEST, FUEL SIPHONED FROM THE LEFT FUEL TANK. FUEL PERFORMANCE CALCULATIONS INDICATED THE ACFT WOULD HAVE USED UP TO 13 GAL DURING THE FLIGHT. IT HAD A 30 GAL FUEL CAPACITY, 15 GAL PER TANK.

Probable cause

THE PILOT'S FAILURE TO PERFORM AN ADEQUATE PREFLIGHT WHICH RESULTED IN AN UNLATCHED FUEL FILLER CAP. CONTRIBUTING TO THE ACCIDENT WAS THE PILOT'S FAILURE TO MONITOR THE FUEL SUPPLY DURING THE 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.
  • API snapshot SHA-256: f6f4b008c280aa4cd88d5c729bf9b4e7eddc6c7f1db0f42c4234708c4dd0ddbf; retrieved 2026-09-21T03:13:27.954Z.
