Narrative:
On August 11, 1997, at 17:00 ADT (Alaska Daylight Time), a float equipped Cessna U206G, N756AD, was destroyed when it impacted water and sank shortly after takeoff from Leisure Lake (also known as China Poot Lake), four miles south of Halibut Cove, Alaska. The commercial certificated pilot, two passengers, and one dog, sustained fatal injuries. The airplane was operated by Halibut Cove Air, LLC, of Homer, Alaska. The flight was conducted under 14 CFR Part 91 as a personal flight. Visual meteorological conditions prevailed at the time of the accident. No flight plan was filed.

The flight departed from the Beluga Lake Seaplane Base, Homer, about 1600, after refueling. The flight stopped briefly in Halibut Cove, where the pilot's wife disembarked, and the pilot's brother-in-law boarded the airplane. The flight then departed Halibut Cove and landed at Leisure Lake. The pilot's brother-in-law left and remained on shore, and two other passengers boarded the airplane.

The accident was witnessed and reported by a husband and wife who live at the southeast end of Leisure Lake. The husband is a certificated commercial pilot. These witnesses were interviewed in their home by the investigative team.

According to the witnesses, the airplane was flying southeast, into the wind, toward the head of the lake at an altitude of 100 feet to 200 feet above the lake. This altitude was described as insufficient to clear terrain at the head of the lake. The airplane was observed entering a steep left bank, in a downwind direction. The airplane rapidly pitched nose down, impacted in a vertical attitude, and immediately sank. They described hearing loud engine noise until impact. The couple responded in a boat, but no occupants were observed exiting the airplane.

CAUSE: The pilot's improper evaluation of the weather conditions which led the pilot to maneuver within the confines of the lake to avoid surrounding terrain and a subsequent inadvertent stall. Factors were the terrain-induced turbulence and gusts.
