What happened
The aircraft departed from an unpaved dirt runway. Shortly after becoming airborne, the pilot experienced a sudden loss of engine power. To manage the situation, the pilot reduced the aircraft's weight by dumping fuel and initiated a forced landing sequence. The aircraft was landed in an adjacent cornfield. Upon impact, the nose section collapsed, leading to substantial damage to the airframe.
The investigation
Following the accident, a mechanical examination of the engine was conducted to determine the root cause of the power loss. The inspection revealed that the supercharger assembly had failed. This mechanical failure is consistent with the reported sudden loss of power during the initial climb phase.
Findings
The primary factor contributing to this incident was the mechanical failure of the supercharger assembly. This failure resulted in an in-flight engine power loss, necessitating a forced landing that caused substantial damage to the aircraft. The pilot's decision to dump fuel and select a cornfield as a landing site were appropriate responses to the emergency, though they could not prevent the structural damage upon touchdown.
