Incident Overview

A pilot engaged in agricultural spraying operations reported an accident involving power lines. According to the pilot's statement, he was spraying a swath of field that bordered power lines. After completing a pass, his attention became focused on a pole, and he subsequently struck nearby power lines. The lines wrapped around the propeller, leading to a sudden loss of power.

Flight and Forced Landing

The pilot initially believed he could return to the airport despite the power loss. However, the power loss increased, prompting him to initiate a forced landing into a field. The landing was characterized as hard, resulting in the engine detaching from the aircraft. Both wings and the fuselage sustained substantial structural damage.

Mechanical Status

The pilot reported no mechanical failures or malfunctions that would have precluded normal flight operations. No further details regarding the aircraft type, registration, or environmental conditions were provided in the report.
