Approach · VFR pattern final
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
Substantial

NTSB narrative

THE PILOT REPORTED THAT THE ENGINE STARTED RUNNING ROUGHLY WHILE ON APPROACH TO RUNWAY 32. BECAUSE HE WAS TOO HIGH FOR A SAFE TOUCHDOWN AND ROLLOUT, THE PILOT ATTEMPTIED A FORCED LANDING TO A FIELD ADJACENT TO THE AIRPORT. DURING THE FORCED LANDING, THE AIRPLANE WAS DAMAGED. THE EXAMINATION OF THE AIRPLANE AND ACCIDENT SITE DISCLOSED THAT THERE WAS NO FUEL IN THE FUEL TANKS NOR WAS THERE FUEL SPILLED IN THE IMMEDIATE VICINITY OF THE MAIN WRECKAGE. THE AIRPLANE WAS LAST REFUELED THREE WEEKS PRIOR TO THIS FLIGHT, AND HAD FLOWN ABOUT TWO HOURS PRIOR TO THIS FLIGHT. THE PILOT ESTIMATED A TOTAL FUEL ENDURANCE OF FOUR AND ONE HALF HOURS; THE FUEL GUAGE INDICATED ABOUT 22 GALLONS OF FUEL ON BOARD AT HIS LAST DEPARTURE. THE PILOT ALSO REPORTED THAT, N412NV HAD A HISTORY OF VENTING LARGE QUANTITIES OF FUEL WHILE PARKED ON THE RAMP. ACCORDING TO THE PILOT, STODDARD-HAMILTON (GLASSAIRE), ISSUED A SERVICE BULLETIN TO CORRECT THE FUEL VENTING PROBLEM; THE SERVICE BULLETIN HAD NOT BEEN ACCOMPLISHED ON N421NV.

Probable cause

THE PILOT'S INADEQUATE FUEL PLANNING WHICH RESULTED IN THE EXHAUSTION OF THE FUEL SUPPLY AND THE LOSS OF ENGINE POWER. A FACTOR WAS THE PILOT'S FAILURE TO COMPLY WITH A MANUFACTURER'S SERVICE BULLETIN.

  • 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.
