Unparalleled reliability records continue to be set.
In about one half the number of flight hours as the Trent, the GE90-115 has about one fifth as many In Flight Shutdowns on the 777 fleet.
No GE90-115 cruise IFSD’s in the last 12 months!
Half the total IFSD’s as Trent, yet almost twice as many fligth hours!
Amazing!

Ok, lets spin the numbers your way.
The entire GE90 series has those 71 shutdowns in roughly 24 million flight hours. The Trent’s 88 IFSD were accumulated in only 18 million flight hours. The Trent is a lot less reliable than the GE90 series.
And in the last 12 months Trent has had 3 IFSD whereas GE90 has had 2…..even though GE90 has 4.6 million FH compared to only 1.8 million FH for the Trent. GE90 flew 2.5 times as much over the last year and had fewer total shutdowns and the -115 had none!

blah, blah, blah.
You’re comparing one model of an engine against an entire series of models from another. A model that makes up the smallest number of a series.
A more balanced view would simply be GE90 v Trent 800. Thats 71 to 88 respectively. Not all that much difference in the grand scheme of it all.
