What happened
The pilot was operating an aircraft for aerial application purposes during nighttime hours. The operations were based out of a dirt airstrip. During the fourth load of the night's work, the aircraft took off from the strip. Shortly after becoming airborne, the airplane struck power lines located at the departure end of the runway.
Following the collision with the wires, the aircraft lost control and landed in an adjacent desert area. The impact caused significant damage to the airframe, leading to a post-impact fire that completely destroyed the aircraft. The pilot did not survive the accident.
The investigation
Investigation of the incident revealed that the pilot had reported seeing a layer of dust hovering over the airstrip. This dust was generated by previous aerial application operations into and out of the strip. The pilot indicated that this dust obscured the power lines from view, making them invisible during the takeoff roll and initial climb.
Findings
The primary factor contributing to the accident was the pilot's failure to see and avoid the power lines during takeoff. The visibility conditions were degraded by the dust cloud, but the pilot proceeded with the takeoff without ensuring the path was clear of obstructions. The fatality count was one.
Safety message
This accident highlights the critical importance of visual clarity during low-level night operations. Pilots conducting aerial application or similar low-altitude work must be aware that dust, smoke, or other particulates can significantly reduce visibility of ground-based hazards such as power lines and towers. Pre-flight checks should include assessing environmental conditions that might obscure obstacles along the departure path.
