A heavily loaded crop duster failed to climb during a go-around from an inadvertent downwind approach because the pilot did not retract the flaps, leading to a collision with a wire fence and nose gear collapse.

What happened

The accident occurred while the aircraft was executing a go-around maneuver following an inadvertent downwind approach to a crop duster strip. The pilot had failed to retract the flaps after initiating the climb. Because the aircraft was heavily laden, it lacked the necessary performance to accelerate and gain altitude with the flaps extended.

The investigation

During the escape attempt, the pilot elected to fly under powerlines located at the end of the runway. However, the aircraft's inability to climb resulted in a collision with a wire fence. Following ground contact, the nose gear collapsed, causing the aircraft to nosed over.

Probable cause

The pilot's failure to retract the flaps during a go-around from an inadvertent downwind approach, which prevented the heavily loaded aircraft from accelerating and climbing, leading to a collision with a wire fence.
