## Probable cause

THE PILOT'S FAILURE TO MAINTAIN AIRCRAFT CONTROL DURING THE LANDING ROLL.

## 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
  - ground loop/swerve - encountered, pilot in command
  - aircraft control - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll

## Analysis

THE PILOT STATED AFTER IT TOUCHED DOWN THE AIRCRAFT BEGAN TO VEER TO THE LEFT.  HE CORRECTED TO THE RIGHT, AND THE AIRCRAFT BEGAN TO SWERVE RIGHT. HE STATED: 'I COULD NOT STOP THE TURN AND IT DEVELOPED INTO A GROUND LOOP.'
