What happened
The pilot was conducting an approach to the airport when the aircraft encountered an unmarked power line. This obstruction was situated approximately 650 feet from the approach end of the runway and extended 46 feet above ground level. Upon striking the power line, the aircraft lost control and crashed into a nearby bean field. The impact resulted in extensive damage to the airframe.
The investigation
Examination of the accident site revealed that the power line was not marked or illuminated, which likely contributed to the pilot's inability to see it during the approach. The location of the wires relative to the runway threshold placed them in a critical area for aircraft on final approach.
Findings
The primary factor in this accident was the presence of an unmarked power line in the approach path. The lack of visual markers made the obstruction difficult to detect, especially if visibility was reduced or if the pilot was focused on other aspects of the landing process. The crash occurred shortly after the initial contact with the wires, indicating that the structural integrity of the aircraft was compromised immediately upon impact.
Safety message
Pilots should be aware of potential obstructions near airports, particularly unmarked power lines and towers. Pre-flight planning should include checking for such hazards in the approach and departure paths. Airport authorities are encouraged to mark or remove obstructions that pose a risk to aircraft operations.
