One assumes a customer will order whatever engine their maintenance facilities are tooled to work with, so changing an order to RR when the carrier is tooled for GE may involve substantial unforeseen cost.

It was never actually tried while I was there, but in theory changing engine manufacturers for a given 787 would require changing the engine pylons as well. Everything else should should work. It should be do-able if the customer desires. Both engines were certified on the 787-8, including dedicated ETOPS F&R for each engine model.
The 747-8 flies with the GenX2B engines, and no there was no path to put the Rolls engines on that airframe.

You just can't replace engine makes overnight, it is impossible to do it without incurring in awfully expensive re-wiring, re-piping, re-softwaring, re a lot of things including re-certification from the FAA and European authorities.
well at least its GE's engine and not Boeing's plane
Its a shame that this is happening with these beautiful GEnx engines. It is putting a bad taste in everyone's mouth about the B788 and B748 which neither planes deserve the criticism. This will be resolved in time. Hopefully
This headline is misleading. That press release is an update to an earlier release, not another engine event.
The real shame of this is that GE has been a reliable source of engines since...well since they have started to produce jet engines. I am confident they will find the source of the problem and resolve it. he question is: It is my understanding that the 787 can hang either the RR or GE engine without a retrofit. Will the users suddenly decide to hang the RR engines and avoid the GE engine? Not sure about the 747-8 if the engines or easily interchangeable.
