The pilot stated that he was performing an agricultural application over a cotton field bordered by a set of power lines. After making a pass over the field, the pilot ascended to fly over the power lines. While turning back towards the field, he “misjudged” the location of a static cable. The airplane’s main landing gear contacted the cable, and the airplane entered a rapid decent. The pilot initiated a forced landing in the cotton field, resulting in a hard landing and substantial damage to the wings and empennage. The pilot report no mechanical failures or malfunctions that would have precluded normal flight.
