Incident Overview
A certified flight instructor (CFI) was conducting a training flight when he initiated a simulated forced landing procedure. The CFI closed the throttle and announced the simulated emergency. Moments later, when he advanced the throttle to clear the engine, it did not respond. Subsequently, a forced landing was performed in a field without further incident.
Investigation Findings
Following the landing, an examination of the engine, fuel system, and related components was conducted. Despite a thorough inspection, the cause of the engine failure could not be determined. No specific malfunction or discrepancy was identified that would explain the throttle's unresponsiveness.
Aftermath
Minor repairs were completed to the aircraft at the field. Once the repairs were finished, the aircraft was flown out of the field without further incident. No other issues were reported during the subsequent flight.
