During landing the nose wheel created a furrow in the turf runway for approximately 30 feet and then dug into the runway causing the airplane to nose over. The airplane came to rest inverted with the nose of the airplane heading towards the south.

The pilot reported to the Safety Board that during the landing roll the airplane had started to oscillate, he was unable to regain control, the nose wheel separated, and the airplane nosed over.
