Last week EVA's third 777-300ER made it first flight. It was line number 572 and was the 210th 777 to fly with GE. RR hit 210 with Cathay's 12th and last 777-300 - line number 567 (at which point PW had 152).
GE will take the lead (for the first time in the entire 777 programme) with #573 (an AF 773ER) but RR will draw level again with #575 (an NZ 772ER). (#574 is a rare PW 777.)
However, with line number 576 (an EK 773ER) GE will hit 212 and neither RR nor PW will have a hope of catching them thereafter.
For the record, PW held the lead in deliveries until line number 275 (in 2000) when RR drew level with them on 92 (with GE on 91!) and RR have held the lead for the past six years.
But the future belongs to GE. When the programme eventually winds up, GE will almost certainly have well over half (they already have 51% of sales) and RR and PW will end up with plus or minus 20% each. (PW currently have 21% sales and RR 28% but these shares will continue to decline.)
Hats off to GE. It's a marathon, not a sprint.
