If you are supervised by the OCC or the OTS, their SAR filing regulations contain the explicit instructions that serve as the basis for the generic advice in the BSA/AML handbook. The mechanics of how you handle the "member of senior management" could vary considerably from those you follow in connection with a director. The former does not involve the same direct conflict between the requirement that you report to the board vs. the prohibition against notifying the subject that a SAR was filed.
There is no mechanism for omitting notification of a director because the SAR is being filed on a family member, business associate, best friend, etc.
In this world you must be oh so smart or oh so pleasant. Well, for years I was smart. I recommend pleasant.
