Cobham B717 fleet take care of it. After all, Cobham do have past operational experience with the Ejet
I think you are mixing your types and companies there old chap. Cobham owned NJS which was sold to QF. NJS has no Ejet experience but a few pilots were on the Ejet at Cobham regional. So there is no corporate or operational knowledge of Ejet within NJS, as distinct from Cobham.
