NTSB Narrative Summary Released at Completion of Accident

The certificated flight instructor (CFI) and the student pilot of the UC-1 Twin Bee completed one uneventful landing on a lake. The CFI then decided to practice glassy water landings with the student, and took off to land on a different lake. A witness stated that the airplane "bounced" when it first contacted the water, and the airplane's right pontoon separated from the wing when it "hit" the water on a second touchdown. The airplane then turned 180 degrees, and sank. The airplane sustained substantial damage from the accident. The pilot reported no mechanical anomalies with the airplane. The winds reported at an airport 11 miles to the southeast, at the time of the accident, were calm.

NTSB Probable Cause Narrative

The flight instructor's inadequate recovery from a bounced landing.
