Arctaurus can't be sure that it will be written off but looking at the damage to the airframe and the fact that it's a 'classic' 742 I would think that it isn't worth repairing.
To give you an idea of the damage it reminds me of the taxing incident with the Saudi 744 where the forward section splits but in the case of the Air Atlanta stress and buckle marks can be seen a long way up the hull aswell when it impacted the sand dunes at the end of the runway.
