Paper Tiger is correct, I think the incident you are referring to is an Embraer 145 landing in Sao Paolo? where the tail end snappe doff just aft of the wing trailing edge. The crew thought it was just a 'firm' landing and were trying to taxi off the runway when ATC told them of the true extent of the damage. Saw the pictures you referred to from inside the aircraft...
will try searching, but don't think I have them anymore.. sorry
