Incident Overview
On July 27, 1985, a float-equipped Cessna TU206G experienced a landing accident at the seaplane base on Lake Tahoe, California. The aircraft, which was on a water landing, nosed over and subsequently sank. The pilot and one passenger aboard were not injured.
Sequence of Events
Witnesses at the scene reported that the aircraft landed on choppy water. The pilot later stated that when the airplane was approximately 5 to 6 feet above the water surface, the seat slid backward. This movement caused the control yoke to move aft, resulting in the tail of the aircraft nosing over into the water. The airplane then sank.
Weather and Water Conditions
According to witness accounts, the water conditions at the time of the accident were described as moderate chop, with wave heights ranging from 2 to 5 feet. Wind speeds were reported to be around 20 knots.
Investigation Findings
No further details regarding the investigation or causal factors have been provided in the source material beyond the pilot's statement regarding the seat movement.
