I'm afraid that I haven't read all of this dick swinging contest, but it strikes me that if SK believe that EC have an unfair advantage in getting certification, then it is lawyers that should be doing the arguing. I guess that at the end of the day money and sales pitch will decide between the two.
What is important is which of the two aircraft is most stable in the hover half way up a mountian at night at the cloud base whilst winching someone off. Or can travel 100s of miles in to the ocean, do an IF decent to autohover in vitually no wind and not blow a life raft over. The rumours I hear is that a SK61 with Carson blades/TR etc would still be the preferable SAR aircraft.
