## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL 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
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (cause)
- Main gear collapsed, landing - roll
  - landing gear - overload

## Analysis

THE PILOT STATED THAT THE AIRPLANE 'GOT AWAY FROM HIM' DURING THE LANDING ROLL. THE AIRPLANE SUBSEQUENTLY GROUND LOOPED, THE LEFT MAIN LANDING GEAR COLLAPSED, AND THE LEFT WING HIT THE GROUND.
