## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - terrain condition - loose gravel/sandy (contributing factor)
  - unsuitable terrain or takeoff/landing/taxi area - selected, pilot in command (cause)
  - terrain condition - rough/uneven (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- Nose over, landing - roll

## Analysis

DURING THE LANDING ROLL THE PILOT LOST DIRECTIONAL CONTROL OF THE AIRCRAFT CAUSING THE AIRCRAFT TO VEER TO THE RIGHT AND NOSED OVER ON ITS BACK. THE PLT WAS LANDING OFF THE ARPT ON A SAND/GRAVEL BAR AND DUE TO THE ROUGH AND UNEVEN NATURE OF THE TERRAIN WAS UNABLE TO MAINTAIN DIRECTIONAL CONTROL OF THE ACFT.
