The reason I thought the item newsworthy was that it seems to me that there have been a significant number of inflight engine shutdowns, in the B787's relatively short service career.
There are a number of sources for this information, but the following website collates them nicely. (Note, I have no connection with the website, or it's owners, and I am sure that there are other sources available).
By my count there have been more than 20 inflight shutdowns on the B788, most on the GEnx, most related to oil issues, either quantity, or pressure indications. The Rolls Royce Trent also figures of course, and there are a number of instances where no reason for the shutdown is given.
A number of the shutdowns have occurred when the aircraft was most likely in an ETOPS/EDTO sector, and of course the B788 is widely used to fly ETOPS/EDTO routes.
At some stage the number of these shutdowns must become statistically significant!
