A floatplane experienced an unexplained engine failure near 1,000 feet, prompting a forced landing on a small lake where the aircraft struck trees and landed hard.

What happened

The incident began after the pilot leveled off at an altitude of approximately 1,000 feet. Shortly thereafter, the engine of the floatplane failed for undetermined causes. In response to the power loss, the pilot identified a small lake suitable for an emergency landing and established a glide path toward the water.

During the approach, the pilot reported lowering the flaps too soon in the sequence. This premature deployment caused the left wing to strike trees located near the shoreline. The aircraft subsequently landed hard on the water surface, resulting in damage to the floats. Notably, the pilot stated that the engine regained power after the aircraft struck the trees.

Probable cause

The engine failure for undetermined causes and the pilot's decision to lower flaps prematurely, which resulted in the left wing striking trees.
