NTSB narrative
THE PILOT DEPARTED FROM THE PRIVATE AIRSTRIP AFTER A SUCCESSFUL ENGINE RUN-UP. DURING THE CLIMB, AT ABOUT 700 FEET ABOVE THE GROUND, THE ENGINE LOST PARTIAL POWER. THE PILOT ATTEMPTED A FORCED LANDING BUT MISJUDGED HIS APPROACH AND THE AIRPLANE STALLED AS HE OVERSHOT THE FAR END OF THE RUNWAY. THE AIRPLANE IMPACTED TERRAIN AND WAS SUBSTANTIALLY DAMAGED. THE ACCIDENT FLIGHT WAS THE AIRPLANE'S FIRST FLIGHT AFTER THE ENGINE HAD BEEN REBUILT. A DETAILED EXAMINATION OF THE ENGINE AND FUEL SYSTEM DID NOT REVEAL EVIDENCE OF MALFUNCTION. ACCORDING FAA CARBURETOR ICING PROBABILITY CHARTS, THE PREVAILING WEATHER CONDITIONS AT THE TIME OF THE ACCIDENT COULD PRODUCE 'SERIOUS' CARBURETOR ICING AT CRUISE POWER. THE PILOT STATED THAT HE APPLIED CARBURETOR HEAT AT THE TIME OF THE LOSS OF POWER, WITH NO EFFECT.
Probable cause
THE PILOT'S IMPROPER USE OF CARBURETOR HEAT WHICH LED TO CARBURETOR ICING AND A PARTIAL LOSS OF ENGINE POWER. FACTORS CONTRIBUTING TO THE ACCIDENT ARE PREVAILING CARBURETOR ICING CONDITIONS, AND THE PILOT'S FAILURE TO PROPERLY JUDGE THE AIRPLANE'S DISTANCE AND SPEED DURING THE FORCED LANDING.

- 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.
