Mick, I believe ozaub is referring to the previous MOM that informed operators of the issue, not the MOM that contains the inspection instructions.
I also do not advocate inspecting all aircraft before further flight. Generally, if it involves fatigue cracking, inspecting “too early” may be counterproductive.
Having said that, fatigue analysis is notoriously error-prone. I have seen exercises conducted throughout the industry to benchmark predictive analysis with subsequent fatigue testing to validate the results, and some of the results are so far off (to the wrong side) it’s truly shocking. That’s one of the reasons why testing is required for certification, even though the OEMs have been trying to get away with less testing and more analysis and modelling. Stating the obvious, testing is expensive.
