THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL.

## 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
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command
- Nose down, landing - roll

THE AIRPLANE STARTED TO FISHTAIL AND THE NOSE VEERED TO THE LEFT.
