Re: If the FAA can be forced to do its job
A FMECA was probably done when the system was still designed to have limited authority. When the change was made to give it full authority, likely someone called for redoing the FMECA analyses, but got overruled. I have no doubt some sort of FMECA was done, it's just when it was done that can make a huge difference. Not that this makes it any more excusable.
The problem for a whistle blower in the aviation world is not only that the organisation that they left will go after them. The aviation industry in general is quite small and "I know a guy that knows a guy". So finding another job with any relevance to your previous one will be completely impossible.
