Hang on a minute!!!
The M.C.A. contract is for 4xS92's up north and 3xAW139's down south, (remember them.. AW139's. They seem to have been forgotten in this discussion.) not S61's! Anywhere!!! To start with Stornoway on October 31st. The S61's are only supposed to be operated for three months while the crews/engineers who TUPE across are trained on their respective new types.
I am sure that Bristow would be more than happy to let CHC have their(BHL) S61's. At a price!!
But having said that, would Bristow be within their rights to call foul if CHC cannot fulfil the new contract? ie. go for a rebid.
