The restriction is to 747-400 vs 747-400ER models. The former are powered by RR engines (at least, at Quantas) while the latter are powered by PW engines. The 747-400ER has not been certified with a fifth engine pod.
- rdl 11y agoQantas flies one 747-400 with GE, though. (and 4 with RR) I was thinking there might be a contractual issue with GE over this, like GE will just swap the engine on demand at their own expense at any station.
- bramblerose 11y agoDuly noted. That one /is/ an odd one, though -- it's a 747-48E that was originally from Asiana, so it might not even have the mount for the 5th engine (as it's an optional extra). Still, you are right that it makes more sense to be related to contracts with the engine mft.
