Summary

On August 14, 2012, a Air Tractor INC AT-502 (N1021D) was involved in an accident near Hanley Falls, MN. The accident resulted in 1 minor injury. The aircraft sustained substantial damage.

The National Transportation Safety Board determined the probable cause of this accident to be: The pilot’s failure to maintain clearance from a guy wire during an agricultural application pass.

The pilot was conducting an agricultural application pass at the time of the accident. He was flying near a set of power line support poles on the edge of the field in order to establish a global positioning system (GPS) reference line for subsequent application passes. He was looking to the left to maintain clearance to the support poles when he observed guy wires in his flight path. He immediately pulled up and rolled to the right; however, the left wing struck a guy wire. The airplane impacted the ground inverted.
