Actually, the intent is not as specific as fuel tanks - it's a desire to use aircraft on contract to the later certification standards. For Heavy types it is intended that they be to Part 29 Amdt 45+ and for medium types (obviously including the 76) to Amdt 40+. Without looking it up, I'm pretty certain that the fuel cell under the cabin 'issue' came up in Amndt 47.
Recognising that you can't achieve this overnight, the intent is to prioritise high hours contracts and contract renewals. Short term and low hours contracts will continue to use older machines for longer. SASless may call that double standards, I'd call it pragmatic and realistic!
There is no replacement that can fit on any of the Shell platforms here in the Gulf other that the S-76. With only 52'X52' helipad with multiple obstructions.
What, apart from an EC-155B1 you mean
