On August 8, 2011, approximately 0530 mountain standard time, an Air Tractor AT-602, N5123L, sustained substantial damage when it impacted a tower while maneuvering near Willcox, Arizona. The commercial pilot, the sole occupant of the airplane, received minor injuries. M and J Bailey, Inc., Dalhart, Texas, was operating the airplane under the provisions of 14 Code of Federal Regulations Part 137.

The pilot reported that he was performing a calibration pass on his target field at an altitude of about 60 feet above ground level when the airplane struck an unmarked 80-foot-tall tower. The airplane's engine caught fire and lost power. During the forced landing sequence, the airplane struck a fence, which damaged the left wing. According to the pilot, the tower had recently been installed without his knowledge.
