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
Loss of engine power
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

NTSB narrative

DURING A DAYTIME EXTENDED DOWNWIND APPROACH AT 300 FEET AGL, THE PILOT ALLOWED THE AIRSPEED TO DROP BELOW 50 MPH. THE ENGINE RPM DECREASED BELOW 1500 RPM AND SUBSEQUENTLY THE ENGINE LOST ALL POWER. THE PILOT MADE A DESCENDING RIGHT TURN FOR THE FORCED LANDING INTO A FIELD. AT APPROXIMATELY 40 FEET AGL, THE PILOT FLARED THE AIRPLANE, BUT LOST CONTROL AND IMPACTED THE TERRAIN IN A VERTICAL DESCENT. NO MECHANICAL MALFUNCTION TO FLIGHT CONTROLS OR STRUCTURAL COMPONENTS WERE FOUND DURING THE INVESTIGATION. ACCORDING TO THE MANUFACTURER'S LIMITATIONS, IMPROPER FUEL WAS IN THE AIRPLANE. THE MANUFACTURER'S FLIGHT MANUAL DID NOT ADDRESS NORMAL OR EMERGENCY PROCEDURES FOR THE AIRPLANE WHEN FLOAT EQUIPPED. THE OPERATOR WHO WAS INVOLVED IN THE MAINTENANCE OF THE AIRPLANE, REPORTED A HISTORY OF FUEL VAPORIZATION IN THE FUEL LINES.

Probable cause

THE PILOT ALLOWED THE AIRCRAFT TO ENTER AN INADVERTENT STALL DURING FLARE AT EXCESSIVE ALTITUDE WHILE EXECUTING THE FORCED LANDING. FACTORS WERE THE PILOT IN COMMAND AND UNAUTHORIZED PERSON PERFORMED CARBURETOR MAINTENANCE ADJUSTMENTS PRIOR TO FLIGHT, AND THE USE OF AN IMPROPER GRADE FUEL.

  • 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: 8fbdbbcc76124578b133797c03aa089e8d1e12f94ff0c41179d975b50a1d1006; retrieved 2026-09-21T15:14:51.653Z.
