The pilot stated that winds were light and the lake surface had about 3-inch ripples. He reported no mechanical malfunction of the airplane. A witness observed the airplane flying slowly over the water in a left bank, at which point the airplane “dropped into the lake” with the left wing hitting the water.
Damage
The left wing sustained substantial damage, being bent upward.
