## Probable cause

DIRECTIONAL CONTROL NOT MAINTAINED.  FACTORS WERE:  CROSSWIND, SOFT GROUND, AND HIGH VEGETATION.

## 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
  - weather condition - crosswind (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - terrain condition - soft (contributing factor)
  - terrain condition - high vegetation (contributing factor)
- Nose over, takeoff - roll/run

## Analysis

DURING THE ATTEMPTED TAKEOFF WITH A CROSSWIND THE AIRPLANE DRIFTED ONTO THE SOFT RUNWAY SHOULDER. THE AIRPLANE BECAME AIRBORNE BUT STRUCK HIGH VEGETATION. THE AIRPLANE TOUCHED DOWN AND NOSED OVER.
