Low freezing point Chinese or Russian fuel has been in use since Adam was a little boy. I am talking about exposure of this fuel for some 30 odd years before my retirement. Can you tell me why this problem has only affected the Trent800.
Perhaps, but we've gone from BC to AD and have come up with some new myrrhs for the lamp oils since then.
Seriously Rev, I think the Trent might be the canary in the coal mine and there are broader issues at work that we've yet to divine.
You ask why only the Roller, I ask how did this get past the design and certification process, and, the entire fleet of airplanes all of these years and flight hours.
