What happened
The private pilot, who was not instrument rated, encountered conditions that placed the aircraft above a cloud layer during flight. Air traffic control provided assistance to help the pilot navigate out of the situation. After descending below the clouds, the pilot faced limited visibility due to fog covering both land and water surfaces.
Attempting to land the floatplane in an inlet, the pilot touched down in shallow water. The floats struck a sand bar, which caused the aircraft to nose over.
The investigation
The investigation focused on the circumstances surrounding the landing and the subsequent damage to the aircraft. Examination of the site confirmed that the floatplane had landed in shallow water within an inlet. The physical evidence indicated that the floats made contact with a sand bar at the bottom of the water, leading to the nose-over event.
Findings
Several factors contributed to the accident. The pilot was not instrument rated, which likely impacted the ability to maintain situational awareness when visual references were lost in the clouds. Weather conditions played a significant role, as fog covered the landing area, reducing visibility of the terrain and water depth. The decision to land in shallow water with obscured bottom features led to the floats striking a sand bar.
The most critical factor was the pilot's loss of situational awareness due to weather and the subsequent inability to judge water depth accurately during the landing attempt.
