The pilot reported that during an aerial application flight, he had reconnoitered the area of operation, but on the last pass, the airplane struck an unseen wire. He recalled that, "the airplane's right wing was trying to drop," and he tried to keep the airplane level, but the right wing collided with the ground and the airplane cartwheeled before it came to rest inverted.

The airplane sustained substantial damage to the fuselage, and both wings.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
