## 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
  - weather condition - crosswind (contributing factor)
  - compensation for wind conditions - poor, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - not corrected, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch (contributing factor)

## Analysis

THE ACFT SWERVED OFF THE RWY INTO A DITCH DURING A CROSSWIND LANDING. THE WIND WAS FROM 180 DEGREES AT 10 KTS. THE PLT SAID THAT HE LOST DIRECTIONAL CONTROL OF THE ACFT BECAUSE OF THE WIND.
