NTSB narrative

THE TWIN ENGINE CARGO AIRPLANE WAS PREPARING TO ENTER A BASE LEG FOR LANDING WHEN THE LEFT ENGINE CEASED OPERATING. DURING THE TRANSITION TO SINGLE-ENGINE OPERATIONS, THE PILOT STATED THE AIRPLANE'S AIRSPEED WENT BELOW THE SINGLE ENGINE BEST RATE OF CLIMB AIRSPEED AND A DESCENT WAS ENTERED. THE PILOT STATED HE WAS NOT ABLE TO TURN ONTO BASE LEG BECAUSE WHEN HE ATTEMPTED TO DO SO THE AIRPLANE'S STALL WARNING SYSTEM WOULD ACTIVATE. THE PILOT STATED HE WAS NOT ABLE TO PITCH THE AIRPLANE'S ATTITUDE DOWN TO REGAIN AIRSPEED BECAUSE OF LOW ALTITUDE. THE PILOT ELECTED TO LAND IN A CORN FIELD. THE ON SCENE INVESTIGATION AND POST ACCIDENT TESTING REVEALED THE LEFT ENGINE'S FUEL PUMP WAS DEFECTIVE AND HAD FLOODED THE ENGINE.

Probable cause

EXCESSIVE FUEL SYSTEM PUMP PRESSURE AND CORRESPONDING EXCESSIVE FUEL PRESSURE AND THE PILOT NOT MAINTAINING THE BEST SINGLE ENGINE CLIMB SPEED.

  • 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. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1992-09-03.
  • API snapshot SHA-256: fd662f65e3c02eab35756088dced50a7c450f2fe6f94cda3c124529c9101e1ed; retrieved 2026-09-18T18:44:10.722Z.
