what they haul up there depends on the damage if any to the airframe or computers that are suspect, if any.
depending on the g's inflicted will determine the special inspections req'd again ,if any.
cabin repairs etc can wait.
interesting if it was multiple sequencing failures.why it would occur and why then drive the aircraft down violently is quite worrying if so.
airbus tech has considerable redundancy available depending on the control surface.
command / monitor inside each and from other computers.
A failed computer is one thing and not unusual, several is quite unusual and uncommanded violent input would be rarer still surely.
If I hadnt seen an oxy bottle blow up rip open an airframe bounce around the cabin and then exit thru the same holes in the floor and airframe I'd say impossible.But impossible happens.
I discount nothing now.
