Analysis

The pilot reported that, during an agricultural application flight, he flew under power lines, climbed, and then made a 180º left turn to the south for another low-level pass. While approaching the field, the airplane struck the power lines and then impacted terrain. The pilot added that he forgot the wires were there and did not see them on the pass. The airplane sustained substantial damage to the left wing and the tail cone. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
