## Probable cause

FAILURE OF THE PILOT TO MAINTAIN DIRECTIONAL CONTROL, WHICH RESULTED IN AN INADVERTENT GROUND SWERVE. THE QUARTERING CROSSWIND AND SOFT TERRAIN WERE RELATED FACTORS.

## 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
  - weather condition - crosswind (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (cause)
- Nose over, landing - roll
  - terrain condition - soft (contributing factor)

## Analysis

THE STUDENT PILOT WAS MAKING A TOUCH-AND-GO LANDING ON RUNWAY 18.  AFTER TOUCHDOWN WITH A WIND FROM 150 DEGS AT 11 KNOTS, THE AIRCRAFT DRIFTED OFF THE RIGHT SIDE OF THE RUNWAY.  SUBSEQUENTLY, THE LANDING GEAR ENCOUNTERED SOFT TERRAIN AND THE AIRCRAFT NOSED OVER.
