THE PILOT STATED THAT HE WAS SPRAYING A RICE FIELD IN FORMATION WITH ANOTHER AIRPLANE WHEN HIS AIRCRAFT EXPERIENCED AN INFLIGHT UPSET DUE TO THE PROPWASH, OR WAKE TURBULENCE, GENERATED BY THE OTHER AIRCRAFT. THE LANDING GEAR STRUCK A RICE LEVEE AND WAS SHEARED OFF. THE AIRCRAFT BOUNCED FROM THE LEVEE AND NOSED OVER UPON IMPACT.
