What happened
The departure phase of the flight began with what appeared to be a standard lift-off from the runway. As the aircraft climbed to an altitude of approximately five to ten feet above the surface, it encountered a sudden disturbance. The right wing abruptly dropped, causing the airplane to initiate an uncommanded right turn.
The pilot immediately attempted to correct the bank angle and heading. Despite these efforts, the aircraft settled back toward the ground and impacted the soft terrain located off the right side of the runway. Following the initial impact, the aircraft ground looped across the surface.
The investigation
Examination of the event focused on the flight dynamics during the critical low-altitude phase. The narrative indicates that the lift-off itself was normal until the moment of the disturbance. No mechanical failures were cited as the primary cause; instead, the pilot attributed the loss of control to an atmospheric phenomenon.
Findings
The pilot reported encountering a whirlwind immediately after becoming airborne. This localized weather event caused the right wing drop and subsequent turn that led to the accident. The lack of sufficient altitude prevented effective recovery before ground contact.
Safety message
Pilots should be aware of the potential for localized wind shear and whirlwinds during takeoff, particularly in conditions that may generate such disturbances. Maintaining situational awareness and ensuring adequate airspeed during the initial climb is critical to recovering from unexpected aerodynamic disturbances.
