Narrative:

On final; passing over the numbers on xxr [and] preparing to touch down probably no more than 10 ft. Above the runway; I experienced a wind shear which I think was a dust devil as I noticed swirling dust off my left wing. I lost all lift and hit the runway and subsequently veered off to the left-hand side. I was unable to control the direction of my aircraft.
