Probable cause

The pilot did not maintain sufficient airspeed while maneuvering, which resulted in an aerodynamic stall at a low altitude.

NTSB narrative

The accident occurred during an aerial-application flight as the pilot maneuvered around a tower. The pilot reported that he had the tower in sight as he maneuvered toward the field being sprayed, and during that turn, the airplane began to shudder as if entering an aerodynamic stall. The pilot attempted to recover from the aerodynamic stall by reducing the elevator input, but the airplane continued to descend rapidly and collided with a tower guy-wire. The pilot stated that there were no preimpact mechanical malfunctions or failures that would have precluded normal operation of the airplane.

Analysis

Primary failure mode
Loss of control
First missed decision gate
