Bristow is pretty confident that had the CHC aircraft been operated by us, it would not have been despatched. Don't forget that the Maint Manual procs and the general profile of the relevant HUMS parameters had been changed/raised since the May ditching and there is surely no way that any operator who was up to speed with events (which we all are) would simply have put it on close monitoring.
However it is one thing to say that in that particular circumstance the problem would have been identified in time, quite another to say that it would always be. Therefore whilst there remains uncertainty about the exact cause, we will not be operating the aircraft offshore (even if we were allowed to).
