Probable cause
The pilot's failure to maintain clearance from the power lines. Factors associated with the accident were the power lines, and the separation of the vertical stabilizer and rudder which resulted in the pilot's inability to maintain directional control of the airplane.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot was spraying a field of wheat and was working under non-active power lines going to an abandoned farmstead. During one of the passes the airplane hit one of the wires separating the vertical stabilizer and rudder from the aircraft. The pilot stated that the directional control was lost, but the aircraft continued to fly, wings level, in a skidding turn to the right. Due to an approaching tree line the pilot reduced the engine power and the aircraft impacted level terrain with the wings level. The pilot stated that the aircraft slid to the left, folding the left main gear under the wing.
