NTSB narrative

THE ACFT COLLIDED WITH A DIRT BANK DURING A FORCED LANDING AFTER THE ENGINE QUIT. THE PLT SAID HE WAS MAKING A SWATH RUNWHEN THE ENGINE QUIT. THE FLAGMAN SAID HE SAW BLACK SMOKE THEN WHITE SMOKE AS THE ENGINE QUIT. POST CRASH INVESTIGATION REVEALED THAT THE FLOAT FULCRUM SCREW (P/N P13773) HAD BACKED OUT OF THE CARBURETOR ASSEMBLY. THIS WOULD RESULT IN ENGINE FLOODING. THE SCREW WAS FOUND IN THE COWLING AFTER THE ACCIDENT. ACCORDING TO THE MANUFACTURER THE SCREW IS INITIALLY SAFETIED TO A PIPE PLUG. IF INSTALLED IN AN ACFT WITH A FUEL PRESSURE GAUGE THIS PIPE PLUG IS REMOVED SO THE SCREW HAS TO BE RESAFETIED.

  • 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: dba2855c79a18564b9b44f7d35ab97a2af9c5e641c7a2eab498004357131065c; retrieved 2026-09-23T22:14:36.626Z.
