Summary
Circumstances:
The pilot was landing at a property prior to conducting crop spraying. During the landing roll, the aircraft veered off the strip and overturned in a wheat crop. A subsequent investigation established the left mainwheel hub had failed due to a fatigue crack, allowing the wheel to travel up the landing gear leg. A partial collapse of the left leg then resulted when the axle dug into the ground. The crack had originated from corrosion pitting on the inner wheel half interior surface, which was not visible with the wheel in situ.
