## Probable cause

DIRECTIONAL CONTROL WAS NOT MAINTAINED BY THE PILOT.  A FACTOR RELATED TO THE ACCIDENT WAS A DRAINAGE DITCH.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, takeoff - roll/run
  - directional control - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, takeoff - roll/run
  - terrain condition - ditch (contributing factor)
