## Probable cause

DIRECTIONAL CONTROL WAS NOT MAINTAINED BY THE PILOT.

## 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)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch

## Analysis

THE STUDENT PILOT SAID THAT WHILE PRACTICING TAKEOFFS AND LANDING, HE LOST DIRECTIONAL CONTROL DURING A LANDING.  HE VEERED OFF THE RUNWAY AND SLID INTO A DITCH.
