My opinion is that the financials have finally caught up with all parties concerned with the A380, and since EK was the largest operator it came down to EK, Airbus and RR.
My other point in another thread, time will tell which OEM engine supplier will support their engine longer, RR or EA, that I think will determine how much longer the A380 will grace the skies offering the faithfull a chance to ride on the frame.
The issue is the turbine blades. For EA, MTU makes them: https://en.wikipedia.org/wiki/Engine_Alliance_GP7000
I suspect they'll keep making small batches for years. Since Safran makes the low compressor, they have a history of good support at low volume.
Bummer for RR the core is the T500 core (retiring A345/A346) which gives poor economy of scale. https://en.wikipedia.org/wiki/Rolls-Royce_Trent_900
That said, support should be profitable (at least once RR gets out of the penalty period) for both engine vendors.. Profitable support lasts a *long* time.[/quote]
Won't be the turbine blades alone that determine the engine support period.
Early EK A380 deliveries had comprehensive engine maintenance contracts of 5+5+5 years. Later EA, and all RR contracts had 15 year, fixed price contracts, part of a package of features to incentivise leasors and financiers.
In theory, RR support commitment runs out for EK in 2036 and EA in 2032, though nothing to stop either buying their way out early.
EA communicated with it's customers regarding ongoing support last year, and RR last week.
