Incident Overview
On a student training flight, the flight instructor initiated a simulated engine failure exercise. The instructor retarded the throttle and activated the carburetor heat to create the simulation. When the exercise concluded, the instructor advanced the throttle and terminated the carburetor heat, but the engine failed to respond.
Forced Landing
With the engine unresponsive, the flight crew executed a forced landing. The aircraft touched down in a field that was unsuitable terrain for a safe landing. The specific nature of the terrain or any damage to the aircraft was not detailed in the investigation.
Investigation Findings
Investigators examined the aircraft and engine systems to determine the cause of the engine's failure to respond. No evidence was found during the investigation that could account for the engine response failure after the simulated exercise. The reason for the engine's lack of response remains unidentified.
Operational Context
The incident occurred during a routine training sortie designed to practice emergency procedures. The exercise involved typical actions for simulating an engine failure: reducing power and applying carburetor heat. The subsequent inability to restore engine power was unexpected and led to the off-field landing.
