Peterjdesouza,
As an3_bolt has said... you are incorrect. The vast majority of the fleets are fitted with an ADF, with SOME (not all) of the A330's an exception.
These days, RNP/RNAV/Whatever it is approved in its place, which is what the A330's use in their place for legalities.
That said, there is no legal requirement to fly anywhere with an ADF anway, as long as you meet all the requirements! Think dual VOR, ILS recievers, and for some fleets, RNP.
The fleets with the ADF's fitted have the pilots apprpriately licenced and qualified to fly approaches with them. Those flying into Melbourne at the moment are having the pleasure!
No story here whatsoever.
