## 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
  - landing gear,tailwheel assembly - movement restricted (contributing factor)
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - compensation for wind conditions - improper, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - uncontrolled, pilot in command
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch (contributing factor)

## Analysis

THE PLT REPORTED THAT A GUST OF WIND WAS ENCOUNTERED DURING THE LANDING ROLL. THE ACFT SWERVED TO THE RIGHT & LEFT RUDDER DID NOT CORRECT THE SITUATION. THE ACFT LEFT THE RWY & COLLIDED WITH A DITCH. THE PLT SAID THAT HE EXAMINED THE TAILWHEEL AFTER THE ACCIDENT & FOUND IT 'UNDULY STIFF.'  HE THOUGHT THIS MADE CONTROL OF THE TAILWHEEL 'WEAK TO NON-EXISTENT.'  HE DID NOT MENTION ANY PREVIOUS PROBLEMS WITH THE TAILWHEEL.
