## Sequence of events

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

- In flight collision with terrain/water, takeoff - initial climb
  - weather condition - tailwind (contributing factor)
  - weather evaluation - misjudged, pilot in command (cause)
  - aborted takeoff - not performed, pilot in command (cause)
- Nose over, landing - roll
  - terrain condition - rough/uneven (contributing factor)

## Analysis

DURING TAKEOFF ROLL FROM A ROADWAY THE WIND SHIFTED FROM A HEADWIND TO A TAILWIND. THE PILOT OF THIS CROP DUSTER TURNED TO AVOID A STOP SIGN ON THE ROADWAY AND ALLOWED HIS LANDING GEAR TO TOUCH DOWN ON A CROSSING ROADWAY. THE AIRCRAFT THEN FLIPPED OVER ONTO ITS BACK IN THE FIELD BEYOND THE CROSSING ROADWAY BECAUSE OF ROUGH TERRAIN. THE PILOT STATED THAT HE KEPT THE PLANE LOW DURING THE TAKEOFF TO FLY UNDER WIRES RUNNING PARALLEL TO THE CROSSING ROADWAY. HE NEEDED TO KEEP THE PLANE LOW BECAUSE HE ROTATED LATER DUE TO THE TAILWIND.
