Matey peeps, the problem is that EK ORDERED another 50 a/c. The first tranche of are 510t variants, for which the good old T900 can produce reliable oomph @72k lbs.
The remainder of the ORDER are 575t a/c, and when you turn up the wick on the T900 to 77k lbs of oomph, longevity on-wing is somewhat reduced.
Will RR fix the issue? Who knows. Will any fix be quick in coming? Likely not.
When i say ordered, i mean firm orders, not options.
How to get out of that pickle? Well, who knows.
