Narrative:

Aircraft experienced a right wing strike following an encounter with LLWS/dust devil. Winds had been called out of the southeast anywhere from 5-8 knots. Three patterns prior to the incident; ops reported winds at 140/7 (a slight right-to-left cross). Two patterns prior to the incident; instructor noticed wind sock showing a slight left-to-right cross as the student was working on touching down with nose properly aligned. On the incident pattern; aircraft experienced light turbulence approaching runway 12. The rest of the approach was smooth down into the flare. Once into the flare; instructor noticed debris (grass clippings; weeds; dust) coming from the right wing forward across the runway from right-to-left (a direct cross) from the surface to a height of ~4'. In the time it took to recognize we were in a debris field from a gust front or a dust devil; the plane had touched down and struck the right wing. Instructor executed a full stop; and taxied clear of the runway while warning other planes in the pattern. Other aircraft in the pattern then reported experiencing LLWS and the airfield was subsequently closed. After taxiing in and shutting down; 2 dust devils were observed by the mishap crew less than a half-mile to the north and northeast of the airfield. Post-flight inspection revealed damage to the right wing. Temps were in the mid-80Fs and the sky was clear.

Narrative: Aircraft experienced a right wing strike following an encounter with LLWS/dust devil. Winds had been called out of the southeast anywhere from 5-8 knots. Three patterns prior to the incident; Ops reported winds at 140/7 (a slight right-to-left cross).

On the incident pattern; aircraft experienced light turbulence approaching RWY 12. The rest of the approach was smooth down into the flare. Once into the flare; instructor noticed debris (grass clippings; weeds; dust) coming from the right wing forward across the RWY from right-to-left (a direct cross) from the surface to a height of ~4'.
