CHC is staying quiet on what's gone on. The statement I have says: "Yesterday [19 Sept], there was a change in personnel in UK and Norway. New Accountable Managers have been swiftly appointed. There has been a brief operational pause in Norway whilst the new appointment is ratified by the CAA; oil and gas operations will resume shortly. Search and Rescue services have been unaffected. There has not been any operational impact in the UK.”
I'm assuming the accountable manager was the RD, in this instance, although can't get that confirmed. The Norwegian GM is/was also one of only three directors of CHC Holding (UK).
