Narrative:

During landing, I encountered windshear very close to the ground. My headwind turned into a tailwind then a powerful crosswind. During touchdown the plane was faster, due to the wind change. I tried to control the aircraft, but ran slightly off the narrow runway. I tried to avoid the taxi lights, but was unable to avoid the VASI board at the tip of my left wing. Only damage to the plane was a small punch hole in the skin of the left leading edge. Therefore, not a reportable accident to the NTSB.
