What gets me is what is the point of a limit to test to if you are not going to enforce it.
If 1% less is ok (Boeing) test to 1% less,
if 3% less is ok (Airbus) make the limit 3% less.
Not enforcing a limit smells bad and does not fill me with confidence.
Strengthening the failure area will change the failure modes to other areas and may well make it fail at an even lower limit as other areas will be bending more to make up for the reduced deflection of the area that is strengthened.
Not re-testing it after a design change like this worries me.
