The underlying circumustances did not cause the sub to sink.
Its the root cause that caused the sub to sink.
An effective corrective action will address both the root cause and the underlying circumustances.
Early days. They are at the containment action stage yet. Corrective action is next followed by preventive action. Root cause will address the last stage effectively. There will likely emerge many root causes and hopefully the prevailing circumstances at the time of the mishap would dictate which of the emergent root causes is the correct one, if the investigation is that good.
Sloppy investigation or analysis would simply allow for the horizontal deployment of the corrective action to be mistakenly seen as preventive action and consequently the root cause determination would not be as effective.
There is a lot of digging to be done, both literally and figuratively. This is where the OEMs will come in. One fears that much of the evidence in terms of chemical residues and explosive signatures would have been washed away. I really feel for this investigation team.
