What happened
The flight ended after the pilot experienced a complete loss of engine power. Unable to maintain altitude or reach a suitable runway, the pilot executed a forced landing in an adjacent bean field. As the aircraft decelerated during the landing roll, the dense vegetation of the crop piled up against the front of the landing gear. This obstruction prevented the nose wheel from rolling freely, causing the airplane to pitch forward and come to rest in an inverted position.
The investigation
Post-accident examination of the airframe revealed significant structural damage. The left wing, horizontal stabilizer, and rudder were damaged due to the impact with the ground and the subsequent inversion. A mechanical inspection of the engine was conducted to determine the root cause of the power loss. The inspection disclosed that the head of the number five cylinder was cracked.
Findings
The investigation focused on identifying why the engine failed and how the accident sequence unfolded. While the physical damage to the airframe was clear, the underlying reason for the mechanical failure remained unclear. The cause of the crack in the number five cylinder head could not be determined from the available evidence. No other mechanical anomalies were identified that would explain the sudden power loss prior to the landing.
Safety message
This accident highlights the risks associated with forced landings in agricultural areas. Dense crops can create significant drag and obstruction during the landing roll, potentially leading to loss of directional control or structural failure if the nose gear is unable to roll freely.
