Accident Narrative
A certificated commercial pilot was operating a float-equipped airplane. According to the pilot's report to the National Transportation Safety Board (NTSB), just after takeoff and at an altitude of approximately 100 feet above the water, the airplane encountered a very strong gust of wind. This gust rolled the wings about 90 degrees to the left. The pilot applied full right aileron in an attempt to regain control, but the airplane descended. The left wing subsequently struck the surface of the water. Upon impact, the left wing separated from the fuselage. The airplane then pivoted 90 degrees to the left, causing the right wing to also strike the water. Both floats were torn from the fuselage as a result of the impact. The airplane eventually sank in shallow water.
Aircraft Damage
The airplane sustained substantial damage to the fuselage, wings, and empennage. The left wing separated from the fuselage, and both floats were detached. The aircraft came to rest submerged in shallow water.
Environmental Conditions
At the time of the accident, the pilot reported wind conditions from the northwest at 20 knots, with gusts reaching 30 knots.
