This is a tough one - no guarantees of prevention combined with no guarantees of detection - different payers with very different opinions about the degree of risk involved in returning the aircraft to service as is.
I think we can draw a few other things from the latest AIBN statement, not the least of which is that there will be a further preliminary report issued on 29th April, the anniversary of this tragedy. Respect.
