Narrative:

The weather in cdg was 400 overcast and the RVR for runway 09R was 1200/1300/1100 when we started the approach. We briefed and flew a monitored cat III to an autoland. The approach was uneventful until approximately 10 feet [AGL] when the autopilot pitched the nose of the aircraft down (prior to touchdown.) we landed firmly and the aircraft bounced. I'm not sure how high we bounced but it was very obvious that we were airborne again. As I was pushing the go around button and disconnecting the autopilot; the nose pitched over again. I set the landing attitude and went to full power. We touched down a second time as we executed a go around. We got airborne and were vectored around the pattern for another approach. This time we did a monitored approach to a manual landing. We saw the runway over a mile out and I disconnected the autopilot and executed a manual landing.

Title: While in the flare mode of an Autoland Approach an MD-11 pitched nose down; striking the ground firmly and becoming re-airborne. The Flight Crew initiated a go-around and successfully completed a second approach to a manual landing.
