NTSB narrative
DURING THE INITIAL TAKEOFF, THE PILOT NOTED A PARTIAL LOSS OF ENGINE POWER AT ABOUT 200 FT AGL. CARBURETOR HEAT WAS APPLIED AND POWER WAS RESTORED. HE FLEW THE TRAFFIC PATTERN AND LANDED, AND THEN HE MADE ANOTHER PREFLIGHT INSPECTION AND A FULL RUN-UP. DURING A SECOND TAKEOFF, HE ENCOUNTERED ANOTHER PARTIAL POWER LOSS AT ABOUT 200 FT AGL. CARBURETOR HEAT WAS APPLIED WITH SATISFACTORY RESULTS FOR ABOUT 30 SECONDS, AND THEN HE TURNED BACK TO THE AIRPORT FOR A DOWNWIND LANDING. HOWEVER, HE OVERSHOT THE RUNWAY AND APPLIED POWER. ENGINE POWER WAS RESTORED FOR ABOUT ONE MINUTE AND THEN DROPPED TO ABOUT 1200 RPM. CARBURETOR HEAR WAS APPLIED, BUT THE POWER COULD NOT BE RESTORED. AT THE TIME, THE AIRCRAFT WAS LOW OVER A WOODED AREA. IT CONTINUED DESCENT INTO THE TREES AND CRASHED. THE TEMPERATURE WAS 22 DEGREES, BUT THE DEW POINT WAS UNKNOWN.

- 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.
