I understand from a behind the paywall article on NBR that AIR have nine of these early model Trent 1000 powered Dreamliners (18 engines, 2 down, 16 suspect) and two of the 2017 engine variant aircraft with the new design fan blades (4 good engines). RR claim the compressor blade corrosion issue can be "managed" through maintenance until they are in a position to retrofit the existing engines with the newly designed fan blades.
I understand this maintenance involves very tight inspection intervals of the affected engines and this is supposed to ensure that the engines are safe for use. Unfortunately a little birdie tells me that the engine that failed on ZK-NZE was only very recently inspected. How much comfort you can get from Rolls Royce claiming their inspection program means these aircraft are safe to fly I will leave for you to decide for yourself. I would not be surprised at all if these planes weren't all grounded in the near future as a precautionary measure. The risk to AIR's SP should be obvious.
ANA have 50 of these aircraft with 100 affected engines and are going through a 3 year compressor blade replacement program which started in 2016. Where AIR are in the queue I have no idea but I seriously doubt this issue is going to be resolved completely by mid 2018 which is what RR implied in their "corporate public relations speak" response to the behind the paywall article on the NBR. I would reiterate the importance of understanding the caveat to AIR's statement that this is not going to affect guidance which was prefixed with the words "At this stage" Anyway I have now posted everything I know about it so I am going to take a break from commenting about this issue unless there is another failure or CAA directive. I won't be making the same mistake of getting dogmatic about this like I did with HBL which I am sure will be a relief to some on here.
