Incident Overview
According to witness reports along the Arkansas River, an aircraft was observed flying at low altitude in a northeasterly direction over the water. The aircraft approached a set of high-voltage power lines that crossed the river at an approximate height of 85 feet above the water surface.
As the aircraft neared the wires, it banked to the left, and its right wing struck the lower set of power lines. Following the impact, the aircraft descended and hit the water tail-first, subsequently submerging.
Investigation Findings
The investigation into the accident revealed that the sounds of the engine and propeller were normal prior to the impact. Additionally, continuity of the flight control cables was established, indicating no pre-impact failure of those systems.
Weather Conditions
At the time of the accident, weather conditions were estimated to be 300 feet overcast with approximately 1 mile visibility.
