What happened
The pilot reported encountering what was described as wind shear during the final phase of the landing flare on runway 14. The aircraft touched down with significant force, resulting in a hard landing. Following touchdown, the pilot lost directional control of the aircraft. Consequently, the airplane departed the left side of the runway surface and collided with the embankment of a large drainage swale located adjacent to the airfield.
The investigation
The investigation focused on the circumstances surrounding the loss of control during the landing phase. Examination of the event revealed that the primary factor was the hard landing followed by an inability to maintain the aircraft within the runway boundaries. The collision with the terrain feature off the left side confirmed the extent of the directional deviation.
Findings
Contributing factors to this accident included the pilot's loss of directional control during the landing roll and the encounter with wind shear conditions. The hard landing was a critical element that preceded the departure from the paved surface. The aircraft struck an embankment, indicating a significant lateral displacement from the intended path.
Safety message
Pilots should be aware of the risks associated with wind shear during the landing flare and the importance of maintaining directional control immediately upon touchdown. Hard landings can compromise steering effectiveness, increasing the risk of runway excursion.
