## Probable cause

THE STUDENT PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL.

## 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 - inadvertent, pilot in command
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch

## Analysis

THE STUDENT PILOT WAS PRACTICING TAKEOFFS AND LANDINGS ON HIS FIRST SUPERVISED SOLO. HE LOST CONTROL OF THE AIRCRAFT DURING THE SECOND LANDING GROUND ROLL. THE AIRCRAFT DEPARTED THE SIDE OF THE RUNWAY AND COLLIDED WITH A DITCH.
