## Probable cause

THE FAILURE OF THE PILOT TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRPLANE DURING THE LANDING ROLL. CONTRIBUTING TO THE ACCIDENT WAS THE PILOT'S IMPROPER USE OF THE AIRPLANE BRAKES.

## 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)
  - brakes(normal) - improper use of, pilot in command (contributing factor)
- On ground/water encounter with terrain/water, landing - roll
  - object - soft
- Nose over, landing - roll

## Analysis

THE STUDENT PILOT COMPLETED HIS FIRST SOLO FLIGHT AND LANDED ON THE RUNWAY. DURING THE ROLL-OUT THE AIRPLANE VEERED LEFT, DIRECTIONAL CONTROL WAS LOST, AND THE AIRPLANE SKIDDED OFF THE RUNWAY. THE AIRPLANE ENTERED A SOFT DIRT FIELD AND NOSED OVER. AN EXAMINATION OF THE RUNWAYS SURFACE REVEALED THE PRESENCE OF ABOUT 100 FEET OF TIRE SKID MARKS LEADING FROM NEAR THE RUNWAY CENTER TO THE AIRPLANE. THE AIRPLANE BRAKES AND RUDDER CONTROL WERE FOUND FUNCTIONAL.
