## Analysis

AFTER SPRAYING MOST OF HIS LOAD, THE PILOT MADE A DRY PASS AND DROPPED A SMOKE FLARE. THE FLARE WAS DROPPED TO CHECK THE DRIFT OF THE AIR RELATIVE TO A SUSCEPTIBLE CROP EAST OF THE FIELD BEING SPRAYED. AFTER DROPPING THE FLARE, THE PILOT MADE A 180 DEGREE TURN AND CROSSED THE FIELD IN THE SAME AREA. HE REPORTED THAT HE ENCOUNTERED THE WINGTIP VORTICES FROM HIS PREVIOUS PASS, THE WINGTIP DUG INTO THE HILLSIDE, AND THE AILERON WAS LOCKED IN A LEFT TURN. THE PLANE CONTINUED ABOUT 200 FT AND THEN CRASHED ON THE HILLSIDE.

- Vortex turbulence encountered, maneuvering - aerial application
  - in-flight planning/decision - improper, pilot in command (cause)
- In flight collision with terrain/water, maneuvering - aerial application
  - terrain condition - mountainous/hilly (contributing factor)
