The jungle drums say that the aircraft will be out for at least a month, and that's from an optimist.
The problem apparently is fallout from the migrated bush in the horizontal stab repair job which led to a cracked brace being discovered in the area and temp repaired until this hangar visit.
This job required the a/c to be jacked and leveled and the stab to be jacked with enough load to take its weight. When the stab jacking process had barely started there was a nasty bang and bits started raining down. The four jack loadings required had been calculated independently by a couple of well qualified people who had done the same job recently. A mystery right now is how the jack points failed so spectacularly with such low loadings, nothing like the final load required.
