## Probable cause

THE PILOT-IN-COMMAND'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL ON LANDING. CONTRIBUTING TO THE ACCIDENT WAS UNSUITABLE TERRAIN SELECTED BY THE PILOT FOR LANDING.

## 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 - rough/uneven (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
- Nose over, landing - roll

## Analysis

AFTER TOUCHDOWN ON THE GRAVEL BAR, THE PILOT LOST DIRECTIONAL CONTROL OF THE AIRPLANE. THE AIRPLANE THEN GROUND LOOPED TO THE RIGHT AND NOSED OVER ON ITS BACK. THE AIRPLANE WAS SUBSTANTIALLY DAMAGED. THE PILOT AND PASSENGER WERE NOT INJURED.
