Aircraft Accident/Incident Report

Thonotosassa, Florida 33592
Thursday, December 18, 2003 16:45 EST

NTSB Narrative Summary Released at Completion of Accident

A witness stated that he was outside his home and noted the accident airplane when it approached to land on the lake as he had seen it do several times previously. On this occasion, the witness said that as he continued to watch the airplane throughout the approach and landing flare/touchdown, he noted that the airplane's landing gear was in the down position, extending below the floats. He further stated that as the floats contacted the water during the flare, the airplane immediately nose dived and flipped straight over, coming to rest inverted in the lake. Examination of the airplane and its systems did not reveal the existence of any preaccident anomalies with the airframe, flight controls, or engine.

NTSB Probable Cause Narrative

The pilot's failure to retract the landing gear prior to landing on the water, resulting in a loss of control, and the airplane nosing over.
