False capture:
That is right as long as you're on the other side of 1.5 mark. If you go for zero margin assumption you're exposed to either this or flight test results that are actually requiring a cert report update.
In Boeing's case there was no need for changes.
Still it seems to me we do not have enough info. Are loadcases comparable (your examples)?
Are these the most critical load cases? Is it the same part of structure?
Too many unknowns...anyway nothing is unsolvable.
Just a little bit of pre-emptive
PR.
