as to bring that airplane back in line with its expected safety standard behavior.
You got me here
What exactly is out of line with the aircraft and its expected standard of safety?
Is it a design fault that was missed in certification?
Is it a manufacturing fault that was missed in Quality Control?
Is it a wear out mode fault that was missed in maintenance?
no doubt there are one or two items in the pot of causal factors, but unless you delinate them it will sound like just another bash the product claim just because it sounds good..
