A float plane pilot, flying at 500 feet AGL across a lake, reported sudden visibility loss after crossing the shoreline. While executing a 180-degree turn to land on the lake, the aircraft struck trees and power lines and fell to the ground.

Incident Summary

A float plane was involved in an accident after the pilot experienced a sudden loss of visibility while transitioning from lake to land. The pilot reported that while flying across the lake at an altitude of about 500 feet above ground level (AGL), the aircraft crossed over the shoreline onto land. At that moment, the visibility suddenly became obscured, according to the pilot's statement.

Pilot Actions

In response to the obscured visibility, the pilot performed a 180-degree turn and began to descend. The intention was to land the float plane on the lake along the shoreline. During the descent, the aircraft collided with trees and power lines before falling to the ground.

The pilot's account indicates a rapid change in conditions upon crossing the shoreline, leading to the attempted diversion back to the lake. The collision with obstacles occurred during the maneuvering phase as the aircraft descended.
