Since the JAGMAN did not go into the Human Factors that were involved, the CO was relieved due to the findings of the AMB. NOTE: The AMB did NOT recommend the CO be relieved, he was relieved for the mishap and the issues that were uncovered during the AMB.
And it shouldn't have. That is so far beyond the scope of an SIR that it would have only served to to reduce the credibility of the report had it been included. Sounded like the senior member handled it properly.
As someone who has sat on both sides of the green table and been involved in both sides of an AMB, I can 100% assure you that the bottom liner on your fnaeb (usually the Air Boss at NZY) has read the SIR by the time you get there for your interview or VTC. This can actually play into your court as well. The fnaeb is interested in getting in, out and over with as quickly as possible. There may EIs (engineering investigations) that are outstanding still. The conclusions of the fnaeb may be based on incomplete information. If, hypothetically, an EI comes back after the fnaeb is finished and proves the existence of a mechanical failure - you could end up with two reports with very different tones. You'd sure like if "the man" knew about the EI report via the SIR before reading the fnaeb package (which was completed prior to the release of both the EI and SIR). Clear as mud?
Bottom line - yes, there is a right way and a wrong way WRT the order that these reports should be released, but before getting too indignant, realize that sometimes the "wrong way" is going to benefit you.....
