What happened
The pilot was conducting a local personal flight when the incident occurred during the takeoff roll. While accelerating for departure, the pilot observed a dust devil located north of the airport, situated adjacent to a nearby freeway. As the aircraft lifted off the runway, it encountered a strong gust of wind associated with the phenomenon. This sudden wind shift caused the aircraft to turn sharply to the left, directing it toward the fence separating the airport from the freeway. The left wing of the aircraft struck the fence upon impact. Two ground witnesses reported seeing the dust devil approach the airport area just prior to the collision.
Findings
The investigation focused on the meteorological conditions and the sequence of events leading to the loss of control. The primary factor identified was the encounter with a dust devil during the critical phase of flight. The strong gust of wind generated by the dust devil altered the aircraft's trajectory immediately after liftoff, resulting in the collision with the perimeter fence.
Safety message
Pilots operating near arid or semi-arid regions should remain vigilant for signs of dust devils, particularly during warm, sunny days with light winds. These localized convective vortices can produce sudden, strong wind gusts that may compromise aircraft control, especially during low-altitude operations such as takeoff and landing. Awareness of local weather patterns and the ability to recognize developing dust devils are essential for maintaining situational awareness and avoiding similar incidents.
