Point taken above about reading the RFM, but comprehension of what is written in the RFM can't be assumed (which is a general comment based on my observations as a teacher on S76). I have seen time and time again, even in crews with thousands of hours experience, not even being on the right checklist for a particular malfunction. There is no point running the wrong checklist perfectly because it probably won't solve the problem. Often it pays to stop reading and just think about the problem, because applying pilot common sense to a problem yields a more sensible outcome than being rail-roaded down the perfectly read wrong checklist.
Again, this comment is made completely not in relation to the specifics of this Bristow ditching.
