But it follows the same pattern as with the Max, i.e. stretching an existing air frame possibly a bit (too?) far.
Changing structural elements' material composition and thickness to gain space and weight looks wonderful on paper I am sure.
Anyway the key figure we miss here is at what percentage of what ( pressurization or wing bending,) the door failed , if it is close or above to 150% there might be nothing much to write about.
I remember the A380 wing failed at 145% , which was , according Airbus : " within 3% of the set 1.5 limit " and therefore deemed acceptable by the regulator .
