## Probable cause

FAILURE OF THE PILOT-IN-COMMAND TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRCRAFT DURING 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 - encountered, pilot in command
- Main gear collapsed, landing - roll
- On ground/water encounter with terrain/water, landing - roll

## Analysis

DURING LANDING ROLLOUT ON RUNAWAY 29R AT MINNEAPOLIS-ST.  PAUL INTERNATIONAL AIRPORT, THE AIRCRAFT SWERVED TO THE RIGHT, PERFORMED A GROUND LOOP, AND DEPARTED THE RIGHT SIDE OF THE RUNWAY AFTER THE TAILWHEEL TOUCHED DOWN.  BOTH MAIN LANDING GEAR COLLAPSED WHEN THE AIRCRAFT DEPARTED THE RUNWAY.
