Aircraft: Piper Super Cub. Injuries: None. Location: Carnation, Wash. Aircraft damage: Substantial.
What reportedly happened: During a local area flight, the pilot decided to make a practice landing on a gravel bar near the middle of a river.
With limited landing distance, he decided to fly his approach at a low airspeed, with the intention of touching down at the very edge of the bar. While on short final, the airplane encountered a downdraft and its main landing gear tires touched the surface of the water, the drag of the water on the tires flipped the airplane onto its back.
