I am completely confident in these aircraft, H 225, because I am pilot of Super Puma since 1990, and I HAD NEVER HAD a RED emergency. I have around 5000 hours flying L1 and 225. For me it is clear that the problem in LN-OJF, it is not inside the MGB. Both scenarios of epicyclic or conical housing would be accused in HUMS or in the FCP. No of them wouldd immediately break without any warning. Because of these I agree with AH and their last statement :

At this stage, the exact cause of this possible event is still unknown. Analysis of the helicopter’s maintenance history has just started and should provide a better understanding of the most likely causes.
