I have no doubt that airbus, consider themselves to be in a theoretical 'good place', regarding the 175. MGB TBO 'gaining by multiples' is just fantastic!
However, enter a offshore operators hangar and the 175 on a 800hr insp will almost certainly have its MGB out of the airframe. In fairness, it is very easy to remove.
To return to thread, Blackhawk gets my vote. Leonardo make a solid and robust MGB,it is just a shame about the flimsy airframe and (allegedly) poor support.
