Air NZ has to cancel a big bunch of flights.

 

Do you think they would have gone with Airbus 350 if the benefit of hindsight was available?

@Batman Title should be useless Rolls Royce Engines not Boeing, The Airlines pick what engines go on the plane when they buy them

 

AirNZ picked the RR for the DreamLiner

@Batman It's not a Boeing Engine it's the engine the airline picks what engines go on the plane they purchase

And not the only model to be faced with issues recently.

 

We may see some of our new birds out of service for a little bit too

 

https://www.flightglobal.com/news/articles/faa-proposes-new-airworthiness-directive-for-pw1100g-461267/ 

 

And then there's the A220 version which set off a few worrying checks https://www.flightglobal.com/news/articles/faa-proposes-checks-of-pratt-geared-turbofans-after-460749/

 

More bypass ratio, more power, bigger blades. Got to give somewhere. Unfortunately it's usually the front end!

How could they have opted for the A350? It didn't exist when Air NZ opted for the Dreamliner.

 

And this whole discussion is pointless anyway - Boeing (and Airbus) don't design engines... And Airbus aircraft are being heavily affected by engine issues as well.

I did chuckle at the online experts saying that. 

 

Along with the ones moaning summer holidays is a crap time of year to take them out. Not like the northern hemisphere is even more busy during our winter or anything..

How hard would it be to modify a 787 to run GE engines instead of Rolls Royce?

Most of the media comments today have been terrible, even from the so called "experts" that media have sought comment from. Most don't seem to realise this issue is very different to the one last year that affected the Package C engines that are on the code1 Dreamliner fleet. This affects the TEN engines which are only on the code2 Dreamliner fleet.

In theory, the 787 was supposed to be designed with common systems for either engine so a swap would be possible.  In practice though, apparently it's still so massively expensive to do an engine swap that it's unlikely to ever happen.

 

It was a "selling point" early on - a claimed advantage over the competition - but never practical.

Relatively easy, Boeing designed them like that, IIRC they even have a common pylon

 

And if anyone was wondering how unhappy Air NZ are about this, their new batch of 787-10s has been ordered with the GE engine.
I surmise that it's not impossible that AirNZ might become the first 787 customer to swap engines, if the RR ones keep on being unreliable and they have a dream run with the GE

Can only assume the plan comes on the back of RRs early november update. Which paints a not so cool picture

 

https://www.rolls-royce.com/media/press-releases/2019/07-11-19-trading-and-trent-1000-update.aspx 

 

Improved high pressure turbine (HPT) blade for Trent 1000 TEN – the final fundamental issue to address – postponed to 2021.

 

Basically testing their repair plan to date, didn't change it. So no mass production and still a WIP

They designed them with the expectation/hope they could use a common pylon, but apparently they can't - and apart from that cost, there's the other problem of where you'd be able to find new GE engines sitting in a warehouse waiting for a buyer to turn up.  Production is to order, and at a guess there's a wait list.

 

Even if you could get the engines, that would cost >US $50 million per aircraft, and you'd be left with $50 million worth of RR engines per aircraft sitting n the back shed.
