## Probable cause

THE PILOT'S SELECTION OF UNSUITABLE TERRAIN.

## 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 - sand bar (contributing factor)
  - unsuitable terrain or takeoff/landing/taxi area - selected, pilot in command (cause)
- Nose over, takeoff - roll/run

## Analysis

THE PILOT STATED THAT HE WAS TAKING OFF FROM A SANDBAR WHEN THE LEFT MAIN LANDING GEAR ENTERED THE WATER AND HE LOST DIRECTIONAL CONTROL.
