NTSB narrative
THE PILOT WAS HIGH AND ABOUT 5 MILES OUT ON THE APPROACH WHEN HE PULLED THE THROTTLE TO IDLE AND CONTINUED TOWARD THE RUNWAY. WHEN HE REALIZED HE WAS LOW, HE ADVANCED THE THROTTLE; HOWEVER, THERE WAS NO RESPONSE FROM THE ENGINE. THE PILOT MADE A FORCED LANDING IN A WOODED AREA. NO MECHANICAL DEFECTS WERE FOUND WITH THE AIRPLANE OR ENGINE. WHEN INTERVIEWED AFTER THE ACCIDENT, THE PILOT AGREED THAT THE ENGINE WOULD NEED SEVERAL SECONDS TO BUILD UP POWER WITH THE THROTTLE AT IDLE.
Probable cause
IMPROPER USE OF THE THROTTLE BY THE PILOT.

Source notes (4)
- 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.
