## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, takeoff - roll/run
  - terrain condition - water,rough (contributing factor)
  - weather condition - high wind (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - preflight planning/preparation - improper, pilot in command (contributing factor)
- Nose over, takeoff - roll/run

## Analysis

THE PILOT STATED THAT DURING THE TAKEOFF RUN ON THE WATER, HE LOST DIRECTIONAL CONTROL OF THE AIRPLANE, DUE TO THE HIGH WIND CONDITION. THE AIRPLANE'S WING TIP STRUCK THE WATER CAUSING THE AIRPLANE TO NOSE OVER ON ITS BACK.
