## Probable cause

FAILURE OF THE PILOT TO MAINTAIN DIRECTIONAL CONTROL WHICH RESULTED IN A GROUND SWERVE.  SOFT TERRAIN BESIDE THE RUNWAY WAS A RELATED FACTOR.

## 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
  - touch-and-go - initiated, pilot in command
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (cause)
- On ground/water encounter with terrain/water, takeoff - roll/run
  - terrain condition - soft (contributing factor)
- Nose over, takeoff - roll/run

## Analysis

THE STUDENT PLT WAS MAKING A LOCAL SUPERVISED SOLO TRAINING FLIGHT.  THE CFI STATED THAT THE STUDENT HAD MADE ONE TOUCH-&-GO LANDING WITHOUT INCIDENT.  AFTER A SECOND TOUCH-&-GO, THE STUDENT ADDED POWER TO TAKE OFF.  THE PLANE THEN SWERVED LEFT, DEPARTED THE RWY & NOSED OVER.  THE STUDENT SAID THE NOSE WHEEL ENTERED SOFT SAND & COLLAPSED, THEN THE AIRPLANE NOSED OVER & CAME TO REST INVERTED.
