He said the airplane's stall horn was sounding as it flew about 20 feet above the water. The pilot said it was clear to him that the airplane would not clear the trees near the lake's shoreline. The pilot said he turned the airplane to the left and reduced the power for landing while in a turn. He said the airplane's left wing stalled , and the airplane pitched down as it rolled to the left. The left wingtip, followed by the corresponding float, and fuselage collided with the water. The airplane sank shortly after coming to rest. The pilot was asked how many degrees of take off flaps are recommended by the manufacturer. He responded by saying one notch, 10 degrees. ## Factual narrative On August 19, 1996, at 1515 central daylight time (cdt), a Cessna 180, N2814A, piloted by a private pilot, was substantially damaged when it collided with the water while maneuvering to avoid trees along the water's edge.
