NTSB narrative
THE PILOT REPORTED THAT SHORTLY AFTER LIFTOFF, THERE WAS A LOSS OF ENGINE POWER AND HE WAS UNABLE TO MAINTAIN ALTITUDE. HE STATED HE HAD TO CLEAR A ROW OF TREES BEFORE HE COULD REACH THE FIELD SELECTED FOR THE FORCED LANDING. HE REPORTED THE AIRPLANE HIT THE GROUND HARD, THE LANDING GEAR COLLAPSED, AND THE PLANE SKIDDED ACROSS THE FIELD. NO PREIMPACT PART FAILURE WAS REPORTED. THE PILOT BELIEVED THE POWER LOSS WAS DUE TO CARBURETOR ICE. THE TEMPERATURE AND DEW POINT WERE 51 AND 32 DEGREES, RESPECTIVELY; THESE WERE CONDUCIVE TO THE FORMATION OF CARBURETOR ICE. THERE WAS NO CARBURETOR HEAT CONTROL INSTALLED ON THE HOMEBUILT AIRPLANE.
Probable cause
CARBURETOR ICE, AND THE OWNER/BUILDER'S INADEQUATE AIRPLANE/EQUIPMENT DESIGN, IN THAT THERE WAS NO CARBURETOR HEAT/CONTROL INSTALLED IN THE AIRPLANE. FACTORS RELATED TO THE ACCIDENT WERE: THE WEATHER (CARBURETOR ICING CONDITIONS), AND OBSTACLES (TREES) IN THE EMERGENCY LANDING AREA THAT PREVENTED THE PILOT FROM FLARING THE AIRCRAFT AT THE PROPER TIME.

- 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.
