I would question the usefulness of tail rotor failure exercises for larger types in the simulator; there is little or no data and you would be reliant upon the software engineer's (or someone else's) view of the probable flight characteristics.
We used to do them in the S61 simulator in Stavanger but only as a handling exercise, not as a representative failure exercise.
The last time I heard of a tail-rotor failure (to one of these larger helicopters) and auto-rotation in the North Sea it was G-TIGK; the crew's actions were exemplary. However, they did have a number of clues that a failure was imminent.
