## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL.  A FACTOR RELATED TO THE ACCIDENT WAS THE SOFT/MUDDY AREA ON THE RUNWAY.

- Loss of control - on ground/water, landing - roll
  - airport facilities,runway/landing area condition - wet (contributing factor)
  - airport facilities,runway/landing area condition - soft (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- Nose over, landing - roll
