On may 4, 2019 N49643 s/n 1813, Bell helicopter 206B was equipted with agricultural equiptment (isolair model 3900 agricultural spray system). The tanks were placed on both sides of the fuselage and were filled with white wash type paint inorder to paint greenhouse roofs. The pilot had previously performed two white washing jobs and on the third white wash greenhouse roof near the intersection of victoria avenue and gonzalas road in Oxnard California the pilot was to spray four loads on the green house roofs, on the first load the pilot had noticed that the aircraft was flying right side low which made the pilot think that the right side tank was still full of paint and did not disperse properly and created an inbalance and center of gravity problem. The pilot proceeded to fly away from the green houses to dump the remaining paint from the tanks but that only increased the center of gravity problem causing the aircraft to roll to the right and spiral to the ground.
