What happened
The flight began with normal operations until shortly after liftoff when the airplane experienced a sudden and severe shaking. Immediately following this vibration, the aircraft settled downward, causing the right main landing gear to impact the ground surface. Rather than remaining on the runway or taxiway, the airplane subsequently began to climb again while the shaking intensified significantly.
The aircraft then settled back down toward the earth and collided with a rice levee. The operator of the aircraft reported that the incident was preceded by a loss of power attributed to a propeller malfunction.
The investigation
Following the accident, an examination of the propeller assembly was conducted to determine the mechanical cause of the failure. Inspectors looked for any anomalies or defects that could have contributed to the airplane vibration or the reported power loss.
The inspection results did not reveal any anomalies in the propeller that would explain the vibration or the loss of power experienced during the flight.
