Color of the 787 Engine Nozzle

Sun Feb 16, 2020 5:02 am

I read you can tell if a 787 is freshly delivered or has been used for some time, simply by looking at the color of the engines nozzles. A freshly build 787 engine nozzles appear to have a light metallic blue coating on them and it slowly become charcoal brown.
I saw a photo of a newly delivered 787-1000 to EVA Air B-17806 and at the background, B-17801 was on towed. Interestingly enough, it is the 801 that still has the blue coating on its nozzles and it has been delivered well over 7 months of service to EVA. Am I missing something here because the B-17806 already lost that blue coating colors and it is quite charcoal brown!

So, am I missing something here.

They replaced the engine probably. Does Eva Air have Rolls Royce engines?

At least not that then. Could be a bird strike, minor damage or something. Engines get replaced from time to time for various reasons.

Not sure if the OP intended for it to sound that way or not, but the blue exhaust nozzle isn't strictly a 787 thing.

Probably still replaced one engine when the plane was delivered. I thought it was common practice to mismatch the engines with an older one for maintenance purposes.
