The Mi 17 will need an EASA Certification and from I have seen of it I think that would be a tough call.
The fuel cells amount to four thin wall aluminium external tanks with no liners. Imagine those in a crash! Not sure how many emergency exits they have now but Shell have managed to get the 'porthole' windows replaced by push-outs although their size might be a bit of a challenge for the larger 'bear'.
I've taught some ex-Mi 17 crews in the last few years and they were not terribly complimentary about certain aspects of its handling. Hearsay is a bad basis for conclusions I know but maybe someone with actual Mi 17 experience can comment.
