Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The lake renegade 250 was making a water takeoff when it started a sharp left turn. The aircraft stopped in the water and the pilot exited without injuries prior to the aircraft turning over. Examination of the aircraft showed that the engine pylon had separated from the fuselage and was attached only by the right flying wire. The owner had the failed parts examined by a independent laboratory and they said that there was evidence of a pre-existing failure. When the parts were examined by the safety board's metallurgical laboratory, they were unable to support the results of the first examination and concluded the cause of the failure was overload.
