Narrative:
My student and I were doing pattern work in an alarus. We had done 8 touch-and-go's without incident. On the 9th; which was to be a full stop; we touched down mains first; the nose wheel came down; struck the runway and the nose gear fork broke off the strut. The landing wasn't soft; but it wasn't really hard either. We rolled a little ways down the runway and then the nose came down on the strut post; which supported the airplane; but the clearance remaining allowed the prop to strike the surface. I believe the problem arose from metal fatigue between the nose gear strut and the fork. There have been similar reports that I've seen of this event occurring.
