  - object - tree(s) (contributing factor)
  - clearance - not possible, pilot in command (cause)
  - weather condition - turbulence (contributing factor)
  - remedial action - inadequate, pilot in command (cause)

## Analysis

THE ACFT COLLIDED WITH A TREE WHILE MANEUVERING IN AN AERIAL APPLICATION OPERATION. THE PILOT STATED THAT WHILE COMPLETING A RUN,TURBULENCE WAS ENCOUNTERED WHICH HE BELIEVES WAS RELATED TO A 20 ACRE FIELD BEING BURNED NEARBY. THE ACFT DESCENDED ABOUT 25 FEET IN THE TURBULENCE AND A TREE AT THE END OF THE FIELD COULD NOT BE CLEARED. THE COLLISION WITH THE TREE CAUSED LOSS OF CONTROL. THE ACFT ROLLED 360 DEGREES TO THE RIGHT WITH THE PILOT MANAGING TO GET WINGS LEVEL FOR IMPACT WITH THE GROUND.
