Primary finding
Probable cause
The pilot’s failure to maintain clearance from power lines during an aerial application flight.
Investigator assessment
Analysis narrative
The private pilot was maneuvering the airplane above a crop field during an aerial application flight. Upon entering the field from the south, the pilot misjudged the airplane’s distance from power lines and struck a power line. He subsequently lost control of the airplane, which impacted terrain and came to rest inverted, sustaining substantial damage to the empennage. The pilot reported no preaccident mechanical problems with the airplane or engine.
