## Probable cause

THE INADEQUATE PREFLIGHT WHICH RESULTED IN DEBRIS IN THE COCKPIT WHICH REDUCED THE PILOT'S VISUAL LOOKOUT. UNSUITABLE TERRAIN ENCOUNTERED DURING THE LANDING WAS A FACTOR.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- In flight collision with object, maneuvering - aerial application
  - object - tree(s)
  - aircraft preflight - inadequate, pilot in command (cause)
  - visual lookout - not possible, pilot in command (cause)
- Overrun, landing - roll
  - unsuitable terrain or takeoff/landing/taxi area - encountered, pilot in command (contributing factor)
- On ground/water collision with object, landing - roll
  - object - fence post
  - object - tree(s)

## Analysis

THE PLT STATED THAT WHILE ON A SWATH RUN, DEBRIS IN THE COCKPIT TEMPORARILY BLINDED HIM.  HE INITIATED A CLIMB BUT THE ACFT COLLIDED WITH TREE TOPS.  HE THEN DUMPED THE CHEMICAL LOAD AND LANDED ON A NEARBY ROAD ADJACENT TO THE FIELD HE WAS SPRAYING.  THE ACFT TRAVELLED OFF THE END OF THE ROAD AND COLLIDED WITH FENCE POSTS AND TREES BEFORE GOING INVERTED. THE ACFT WAS DESTROYED BY FIRE.
