From my recollection of this accident one of the key if not the key error was the disregarding of stabilised approach criteria. This technical fault had occured on a number of occasions previously without going close to the same result.
They got very busy late in the approach trying to join the glideslope from above. Whilst it is possible for a crew with good SA to successfully and safely land an aircraft after getting stable late the reality is that the chances deminish very quickly the close you get to the ground. In this case the normal ques that would have let them know they had a problem were masked by the high ROD and low power required to join from above. They were distracted by trying to still get checks done whilst things were already going wrong. If they had knocked off the approach when they went through the stabilised approach point it would have ended without any of us knowing about it.
