NTSB narrative

ACCORDING TO THE PILOT, THE AIRCRAFT WAS ABOUT 50 TO 100 FEET AGL IN THE TAKEOFF INITIAL CLIMB WHEN THE LEFT ENGINE SUDDENLY QUIT. THE PILOT CORRECTED FOR THE YAW CONDITION AND HAD JUST RESTABILIZED THE AIRCRAFT WHEN THE LEFT ENGINE SURGED INTO LIFE. THE PILOT DECIDED TO LAND THE AIRCRAFT AND IT IMPACTED GEAR UP IN A LEVEL ATTITUDE IN A GRASSY AREA BETWEEN THE RUNWAYS. FAA AIRWORTHINESS INSPECTORS DETERMINED THAT THE AIRCRAFT WAS OPERATING ON AN AUTOMOTIVE FUEL SUPPLEMENTAL TYPE CERTIFICATE. A QUANTITY OF WATER AND RUST COLORED SEDIMENT WAS DRAINED FROM THE LEFT FUEL TANK SUMP. NO OTHER SYSTEM ABNORMALITIES WERE IDENTIFIED DURING THE EXAMINATION OF THE AIRCRAFT.

Probable cause

AN ENGINE POWER LOSS DUE TO FUEL CONTAMINATION.

  • 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 1992-05-05.
  • API snapshot SHA-256: 2ecca84f53c74f925c1cf9469a4cd3da9ee5541f86e8caef4e2951b71130eabb; retrieved 2026-09-23T03:11:04.673Z.
