Dream Buster see Annex 13.
More details given in ICAO Doc 6920 AN/855/4 Manual of Aircraft Accident Investigation.

Based on the concluding remarks, we might assume that EGPWS was serviceable and thus provided warnings. In the situation described (ref to Google Earth) the alert period would have been quite lengthy. Thus, why didn’t the crew respond? Or if they did, why was it too late or insufficient to clear the ridge?
A visual circuit / circling procedure (i.a.w. a published procedure or not) should still be flown visually. If the aircraft is judged as going to enter cloud, or inadvertently does so then there should be an immediate pull up.
There are some similarities with other incidents where crews failed to respond correctly, in these events there were mistakes in awareness and visual illusions; did the crew in this accident have an illusion of invulnerability?
