## Analysis

WITH THE WIND AT 5 KTS DURING A SPRAYING OPERATION, THE PLT WAS FLYING A CIRCULAR PATTERN TO DISTRIBUTE THE CHEMICAL BECAUSE IT WAS ADHERING TO THE WINDSCREEN REDUCING HIS VISIBILITY.  DURING A SPRAY PASS THE RT MAIN LANDING GEAR WHEEL SEPARATED AFTER COLLISION WITH AN IRRIGATION PIPE.  THE FLT DIVERTED TO A SUITABLE ARPT AND THE ACFT WAS SUBSTANTIALLY DAMAGED AFTER TOUCHDOWN.
