What happened
The incident occurred while the pilot was engaged in an aerial application flight. During the execution of a procedure turn, the aircraft's engine ceased operation without warning. Unable to maintain altitude or regain power, the pilot initiated an emergency landing in an adjacent field. The impact resulted in substantial damage to the airframe.
The investigation
Following the accident, investigators examined the wreckage to determine the mechanical status of the aircraft at the time of impact. A thorough inspection of the fuel system revealed that both fuel tanks were completely empty. Further examination of the fuel sump indicated the presence of approximately one tablespoon of residual fuel. No other malfunctions or failures in the aircraft's systems were identified during the post-accident analysis.
Findings
The primary factor leading to the accident was fuel exhaustion. The lack of fuel in the tanks and sump confirmed that the engine stopped due to a depletion of its power source rather than a mechanical failure. This led to the forced landing in the field, which caused substantial damage to the aircraft structure.
Safety message
Pilots conducting aerial application or other intensive flight operations must ensure adequate fuel reserves are calculated and verified prior to takeoff. Regular monitoring of fuel quantity during flight is critical to prevent fuel exhaustion, which can lead to engine failure and forced landings in unprepared areas.
