|Quoting JoeCanuck (Reply 8):|
Does anybody have a breakdown of the expenses which add up to 148 million dollars to upgrade a C-5 to the M model?
4 CF6-80s and a spare ... $50 million?
HPT disc failures should AD
'd now. The CF6 was developped from the TF39, which probably eased integration compared to a totally different engine.
I think a big operation plus for the CF-6-80 is that you can get MRO
and parts everywhere. Is it the most used turbofan? A300, A310, A330, B747, B767, MD11, C-X all use CF6-80 versions.
CF6 shops, warehouses everywhere. Not that MRO
will be outsourced but its handy to e.g. top up stocks fast/ efficiently. Probably more important then the better fuel efficiency the GENX could have offered.
Maybe this mod will have the C5 fleet finaaly meet its original dispatch reliability targets. Bad news for the An124 operators that made a fortune out of US / NATO operations during the last 15 yrs.
