What happened
Following a routine landing, the pilot initiated the takeoff roll. After retracting the flaps and applying power, the aircraft began to accelerate down the runway. As airspeed increased, the aircraft started to drift laterally off the paved surface.
The pilot attempted to maintain directional control using rudder input, but the aircraft continued to veer off the runway. Before the nose wheel could be lifted or power reduced effectively, it dug into soft mud adjacent to the runway. The force of the impact caused the aircraft to flip over.
The investigation
Examination of the event focused on the sequence of events during the takeoff roll. The primary mechanical factor identified was the loss of directional control due to the nose wheel penetrating soft ground.
