Accident Overview
The agricultural airplane, while in flight for a local aerial application operation, collided with a power line. The pilot was maneuvering the aircraft when the accident occurred. Examination of the accident site determined that the commercial pilot had attempted to fly under the power line. The upper portion of the vertical stabilizer made contact with two power transmission wires. These wires were situated 19 feet above ground level. After the wire strike, the airplane descended and impacted the ground. A postimpact fire ensued.
Investigation Findings
Investigators conducted a thorough examination of the airplane's engine, airframe structure, and maintenance logbooks. The inspection revealed no evidence of any mechanical or maintenance anomalies that would have prevented normal operation of the airplane. The conclusion was that the airplane was airworthy prior to the accident. The investigation focused on the pilot's decision to fly under the power line as the immediate cause of the wire strike.
Wreckage Examination
The wreckage was examined at the accident site. The vertical stabilizer showed evidence of contact with wires. The power line wires were measured at 19 feet above ground. The postimpact fire consumed portions of the aircraft. No other preexisting damage or failures were noted.
