Narrative:
We were flying the VOR DME approach. When we flew over the 4 DME fix the aircraft made a right turn with a bank of at least 10 degrees with a heading change of about 15 degrees before the first officer disconnected the autopilot. We had just broken out of the clouds so we corrected the heading and flew in visual conditions to a normal landing. After review and talking to others I'm sure it was a database problem. Check all new approaches in the simulator before flying.
