Incident Overview
A pilot flying an agricultural airplane reported that after completing a spraying operation, he climbed a few hundred feet to program the onboard GPS before heading to the next field.

The collision occurred at the 500-foot level of the tower.
Aircraft Control and Landing
Impact with the guy wire caused a momentary loss of control, and the airplane abruptly turned about 90 degrees. The pilot managed to maintain control and performed an uneventful precautionary landing in an open wheat field approximately one mile southeast of the tower.
Charting and Weather
The tower was not depicted on the Sectional Chart; however, it was listed in the current Aeronautical Chart Bulletin in the Airport/Facility Directory. At the time of the accident, weather conditions were reported as 1,100 feet overcast with a visibility of 4 miles in haze.
