Analysis

After spraying 2 fields, the plt was en route to spray a 3rd field when a severe vibration of the acft was encountered. He elected to land in the 1st available field & dumped his chemical load. During the landing, the acft hit a terrace & nosed over. The plt stated that he did not realize the field was uneven & terraced until the acft was on the ground. Grass & tall weeds were growing in the field. An investigation revealed that the upper right eng mount had failed. No fatigue was found; however, there was evidence of hammering, indicating multiple impacts after the initial failure.
