Analysis

The plt was executing a turn around maneuver to continue spraying when the #2 cyl broke free from the eng & it completely shut down. The acft struck the levee of a bean field & flipped over, coming to rest in an inverted position. Post crash examination revealed that the crankshaft had broken where it holds the outer counterweight, effectively shutting down the eng.
