Sunday, September 12, 1999 13:27 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot told police he was going to practice a touch and go landing on the lake. He said that on touchdown the airplane decelerated as if 'the brakes were locked,' and the airplane cartwheeled. The pilot did not indicate any mechanical problem with the airplane. Subsequent to the accident an examination of the wreckage was conducted. The inspector said the airplane was broken into three major pieces. He said his examination of the wreckage failed to reveal any pre-impact anomalies. He said landing gear was in the retracted position. He said that when he talked to police authorities they told him, 'According to witnesses [the pilot] was attempting a landing on Bruin Lake when he lost control of the aircraft. One of the sponsons hit the water causing the aircraft to flip.'

NTSB Probable Cause Narrative

The pilot's improper touchdown during a water landing.
