I think the pictures chosen by the AIBN simply contain items that they are examining - no more than that;
There was an amber warning in the days before the crash - that would have to be looked at as part of any investigation methodology.
They have a destroyed gear - that would have to be explained.
They have an incomplete suspension bar assembly so they need to try and find the rest of it and make sense of the wreckage.
However, they are clearly not at a position where they feel they understand the causes of the accident sufficiently to (a) Make a more specific statement (b) relax the ban on commercial flights.
While they would obviously continue to search for missing components in any case, their emphasis on this seems to suggest that lack of specific items is directly hampering their ability to properly understand the principal initiating cause - or more likely provide enough evidence to make a definitive statement.
