## Probable cause

THE STUDENT PILOTS FAILURE TO MAINTAIN DIRECTIONAL CONTROL DURING THE LANDING.  A FACTOR IN THE ACCIDENT WAS HIS LACK OF TOTAL EXPERIENCE.

## 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)
  - lack of total experience, pilot in command (contributing factor)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - rough/uneven
- Nose over, landing - roll

## Analysis

THE 28 HOUR SOLO STUDENT PILOT WAS PRACTICING TAKEOFFS AND LANDINGS ON RUNWAY 25R AND WAS ON HIS FOURTH LANDING WHICH WAS TO BE A TOUCH AND GO. THE AIRCRAFT DEPARTED THE LEFT SIDE OF THE RUNWAY AND COLLIDED WITH ROUGH TERRAIN AND NOSED OVER INVERTED. THE PILOT STATED TO FAA SAFETY INSPECTORS THAT IT FELT LIKE THE NOSE WHEEL STEERING DID NOT WORK. THE AIRCRAFT WAS INSPECTED BY FAA AIRWORTHINESS INSPECTORS WHO REPORTED THAT NO PREIMPACT MECHANICAL MALFUNCTIONS OR FAILURES WERE IDENTIFIED.
