Qatar Airways has agreed to pick up four finished Airbus A350-900s, four months after the Middle Eastern carrier cancelled delivery of the aircraft.

Airbus says the airline has agreed to "continue to take delivery" of the four associated aircraft by the end of the year.

Qatar Airways had 43 A350-900s on order but cut four of them in June, leaving it with a total commitment of 39.

By the end of September the carrier had taken delivery of 15 of them.

Qatar Airways has also ordered 37 A350-1000s. The first of these is still due for delivery before the year-end.

Airbus chief financial officer Harald Wilhelm, speaking during a third-quarter briefing, said the ramp-up of A350 was progressing well.

Do I see an impending 2 yr high?
My portfolio could do with a bit of a surplus for a change...

Another positive is the pension fund surplus.
This is a rare situation in these times.
This months pension statement says that the surplus will further increase from last years healthy surplus.
It will not confirmed for a while, but it is 'anticipated'.
Good news.

RogerRail. Possibly,although the Letter of intent to buy the 787s was actually signed in Feb 2017 and it was the formal contract which was signed a few days ago. I am hoping that it could be due to some positive update from Emirates re an A350 or A380 order in the light of Emirates CEOs comments in Sept.

Maybe its due to another 19 x 787 orders for Singapore Airlines on its way, though I doubt it

RR up another 2% so far today with no particular news to tigger the rise that I have seen. Maybe they will have some positive news to announce at the Dubai airshow next month. Presumably the Gulf carriers in particular will have some orders up their sleeve as they have been rather quiet on that front recently.

[wad collector] 18/10/2017 14:27

.....so all General Electric engines should be grounded indefinitely? That would be good for RR!

Latest per Flight Global:
BY: DAVID KAMINSKI-MORROW LONDON
Operators of Airbus A380s with Engine Alliance GP7200 powerplants are being ordered to conduct an urgent inspection of the engines' fan hubs for damage.

The US FAA's emergency directive follows the uncontained failure of a GP7200 which, it says, had accumulated 3,527 cycles since new.

It describes the powerplant as a "relatively high cycle engine". The directive requires removal of the fan if damage or defects are found during the one-time visual inspection.

Investigators have been probing the uncontained GP7200 fan failure on an Air France A380 over Greenland on 30 September. The aircraft, bound for Los Angeles, diverted to Goose Bay in Canada.

The directive is intended to prevent failure of the fan hub, damage to the engine, and potential damage to the airframe.

Transportation Safety Board of Canada, in a preliminary bulletin, says the Air France A380 sustained "substantial damage" to the starboard outboard engine inlet during fan separation, and visible damage to slats and fairings either side of the powerplant.

Components have been located in Greenland while a runway inspection, says the bulletin, discovered debris on the arrival runway at Goose Bay.

Operators must conduct the engine inspection within two weeks if the fan hub has logged at least 3,500 cycles.

This deadline extends to five weeks for fans with 2,000-3,500 cycles, and eight weeks for all others.

It states that the inspections are an interim measure, because the cause of the fan failure has yet to be determined.

Strange that there is not coverage of this in the world press, mid air is not common as engine is not at maximum thrust as in take off. Containment is at the heart of this and I am told RR have this covered. Any criticism of GE might be called "Fake News".

standish11, where did that report come from?

[finess] 10/10/2017 09:37

If that had been a RR engine GE would make it world news. Alliance have aluminium with a kevlar wrap, I think Rolls use titanium. I am told Alliance use components from G E.

Looks like it was a disc burst. Hope they find the parts.

[arf dysg] 03/10/2017 12:17

careful, a disc burst is indeed uncontainable and that's the kind of event which should never happen.

Yes, I am beginning to understand jet engine design more and what you describe is more than one would expect if a fan blade had broken off. I wonder whether it has influenced or will influence future engine buying decisions?

I purchased RR book on the jet engine. It is excellent and encompasses pretty much everything but is heavily engineering based - as you would expect - and so although still very helpful to the layman it will be difficult to follow in parts. My current Sunday afternoon reading amongst other things! :) I recommend it:

disc burst?
uncontainable.

Minerve,

From that BBC report: "Photos taken by passengers showed the cowling, or engine covering, completely destroyed, and some cosmetic damage to the wing's surface."

I beg to differ. It's not just the cowling. The amazing thing is that the fan and the entire fan-case surrounding it have disappeared. Such a large sub-structure has been lost, yet appears to have been cut off cleanly.


When you're about to get on the plane, you may look at an engine underneath the wing and notice that most of the front of it consists of some large blades (24 for some modern engines, though older ones tend to have more smaller ones). In the picture of the damaged engine, one can see that those blades are simply not there any more, so the whole lot has gone, along with the hub (think of propeller blades attached to a central hub) and the shaft, and the surrounding casing.

That's a huge chunk of the engine which is missing, so investigators are most likely looking at a region of Greenland to see where the bits fell.

The cowling is a thin (sort of) outer covering to encourage smooth streamlined flow over the outside of the engine. What's not usually visible, however, is just inside the cowling: a thick very strong cylindrical enclosure designed to catch and contain any detached blade, so it doesn't go whizzing through the fuselage, chopping passengers in half. This enclosure, the casing, is simply not there any more in the pictures in the BBC report. It should be strongly attached to the front of the engine, so something must have gone very wrong for it to have been ripped off.

A fan blade may come off once every hundred million engine hours, but even that remote possibility is dangerous enough that the casing is there to contain the blade and stop it going any farther.

Just saw that too ; good to see rivals troubles...

[minerve] 01/10/2017 00:07

Oh dear, General Electric & friends... This isn't good! LOL
