Background
The incident involved an agricultural airplane that was in the process of taking off from a private airstrip. According to the pilot's report, the engine was performing as expected during the initial portion of the takeoff roll.
Event
As the takeoff progressed and the tail of the airplane lifted off the ground, the pilot noticed that the engine began to lose power. The loss of power was partial, and the aircraft could not sustain flight. The pilot was forced to execute a forced landing. The aircraft then collided with a berm that was located beyond the departure end of the runway.
Damage
After the collision with the berm, the airplane came to rest upright in a rice field. The wings of the aircraft sustained structural damage due to the impact.
Investigation
Following the accident, a detailed examination of the airplane's engine and fuel control system was performed. The examination did not reveal any anomalies or malfunctions. As a result, the specific cause of the partial loss of engine power during takeoff could not be determined. The investigation did not identify a definitive reason for the power loss.
