Analysis

The pilot reported that upon completion of an aerial application of fungicide, he made an end clean up pass. He reported that the airplane struck a transmission line wire that he did not see, and then impacted the ground which resulted in substantial damage to the right wing and vertical stabilizer. The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
