Yesterday I had some time to do a little reading in various fleetlists.
I have of course been aware of Air New Zealand changing from RR to GE engines on its 747-400s (exept the three original ordered ZK-NBS, -NBT & -NBU). Since the integration of ZK-SUH & ZK-SUI which was acquired second hand with GE engines, all new 747-400s for ANZ have been GE powered.
Qantas have three GE powered 747-400s in its fleet (VH-OEB, -OEC & OED) which also was acquired second hand from Malaysia Airlines (2) and Asiana.
According to the fleetlists Qantas have chosen GE to power the ordered 747-400LRs. Why is this?? Does RR not offer any RB211s for this LR-model or have Qantas simply chosen GE as a more economical engine? I know the ANZ at one time stated that the GE engines was more reliable and economical than the RRs! Has Qantas come to the same conclusion or .... ???
And yes - I know that Qantas A380s will be RR powered but as far as I understood their A330s will have GE-engines! A wind of change by the Kangaroos????

I don´t get the point. Qantas have 18 RR powered 747-400s and a number of RR powered ex. BA 767-300s! They should have enough tools for RR engines I figure?? Or is the RB211 offered for the LR-model very different from the RB211-524H??

Sorry for the confusion.
The tools to maintain the current B747-400 RR powered engines are different from the ones needed to maintain the RR engines which is offered on the B747-400LR which means this 2 engines are kind of a different. As for the GE powered B744s they have now, tools needed to maintain it's engines are similar that with the B767-300s they have now, and will be similar too, to the GE engines that are powering the A330s.

I remember reading somewhere that QF stated that they were more impressed with the CF6 compared to the RB211 on the 744, and that they therefore decided on the American engine for their 744ERs. The CF6 has clearly grabbed most customers for the 744, something which might have to do with it being the least thirsty. QF has had a couple of years to compare the performance of the two engines against each other on the 744, so the switch from RR to GE is not accidental, I guess.
