The pilot reported that, during an aerial application flight, about 15 to 40 ft. agl and traveling westward with the sun in his eyes, the airplane's rudder struck a wire and separated. The pilot subsequently landed the airplane without further incident. The pilot added that he thought the airplane already cleared the wire when the collision occurred.

The airplane sustained substantial damage to the rudder.

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