Unless you have one of these bolts in your hand you cannot know if it failed in tension or from fatigue. The fan assembly will have been tested rigorously on a development rig over many hundreds of cycles before the design was signed off for production. Now we know this engine is a 'bitser' (bits of one design combined with bits from another design) but I have no doubt that the combination was also tested through many cycles before being signed off. What I am getting at here is that this failure seems to me to be a unique event, and may never occur again. So all the AD's in the world are not going to make much difference. But as I have already said we have no information at all right now on this forum about which bits are actually available for inspection. Till we have....
