NTSB narrative
DURING A DESCENT, THE PLT PULLED THE THROTTLE TO REDUCE POWER WITH NEGATIVE RESULTS. HE AGAIN PULLED THE THROTTLE TO REDUCE POWER & THE MANIFOLD PRESSURE GAUGE INDICATED THAT THE ENG POWER DROPPED TO IDLE. HE ATTEMPTED TO PUSH THE THROTTLE, BUT WAS UNABLE. HE THEN MADE A FORCED LANDING. DURING THE LANDING ROLL, THE ACFT WAS DAMAGED WHEN IT COLLIDED WITH A FENCE & A TREE. AN EXAM OF THE FUEL SERVO REVEALED THAT THE THROTTLE PLATE HAD SEPARATED FROM THE THROTTLE SHAFT DUE TO IMPROPER SECURING OF THE ATTACH SCREWS DURING OVERHAUL. THIS RESULTED IN THE LOSS OF POWER DUE TO RESTRICTED AIRFLOW INTO THE INDUCTION SYSTEM.
Probable cause
SEPARATION OF THE THROTTLE PLATE, DUE TO IMPROPER SECURING OF THE ATTACH SCREWS DURING AN OVERHAUL.

- 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.
