Analysis

Plt stated that during loading for aerial application, he failed to note approaching roll cloud which usually signifies localized turbulence and strong, gusting winds. On takeoff roll, wind shift noted and at 100 ft altitude, heavy turbulence was encountered. The liquid load began to slosh and the acft lost altitude, eventually settling into a corn field. No attempt to jettison load was made.
