Read the full NTSB narrative
The certificated commercial pilot was attempting to takeoff from a lake with 2 feet tall, rolling swells. The pilot said that during the takeoff run, before a safe flying airspeed was attained, the airplane floats struck a large wave, and the airplane lifted off the water prematurely. He said that before he could react, the left wing stalled, and the airplane collided with the water. During the collision, the floats were torn off the airplane, and the airplane sank. The airplane sustained substantial damage to the fuselage, empennage, and wings. The closest official weather observation station is Iliamna. On August 25, 1999, at 0553, an Aviation Routine Weather Report (METAR) was reporting in part: Wind, 259 degrees (magnetic) at 7 knots; visibility, 10 statute miles; clouds, 7,500 feet broken; temperature, 51 degrees F; dew point, 46 degrees F; altimeter, 29.52 inHg. Official civil twilight for Iliamna was at 0610.
