Two SIA 787s grounded owing to Trent 1000 TEN HPT issue

Tue Apr 02, 2019 6:24 am

SQ is grounding a part of their 787-10 fleet. They have found the same fan blade cracking on the Trent 1000-TEN engines as on their older Trent 1000 engines.

RR will see some additional compensation payments go out of the door.

So in other words the problem that was suppose to be fixed with the Trent 1000-TEN, isn't fixed.

From doing a quick check there are 6 of 9 787-10's currently not flying, 3 of which haven't flown since the weekend and the other 3 that haven't flown in the past 24 hours. This would explain why SQ215/216 to PER has been subbed by other equipment over the past couple of days.

Anyway not good news for those operators that have already been affected by RR issues already

If the engines are still having their 2018-ish problems, even the -TEN, then it's tough to overstate how bad this could be for RR, and by proxy Boeing and operators.

I wonder if there will be any issues on the Trent 7000 as well. These engines are derived from the Trent 1000-TEN.

SQ is a major Trent XWB operator and these are in service for a longer time than the Trent 1000-TEN. So far, we have not heard of any major problems that require grounding of its A350s.

It wil take years for PW to develop something to power a B787.

RR has a big problem if they can't resolve this yesterday. If confirmed, this is going to hit the B787 program very badly unless Boeing can somehow get GE to pick up the slack on new airframes.

Considering that this is the sole engine on the A330neo and that RR are the sole supplier on the A350XWB, Airbus can't sit by and let this happen to them. At this point and given the simultaneous rising likelihood of a nodeal Brexit, Airbus should offer to take over all the assets of RR for a symbolic amount and absorb the company, even if they have to pay compensations to B787 customers in the future.

If RR gets into deeper troubles, Airbus is going to be in eveb deeper booboo.

That is the perfect summary.

RR looks like it has lost its way. No wonder Boeing doesn't want them to feature on 797. Sure, RR might have withdrawn from the campaign, but I bet it's becaurse they knew they are on a hiding to nothing.

Fall from grace for Rolls. People here remarked how Pratt no longer knew how to build engines. RR appears much the same.

What a debacle!

And they'll have exactly that (time frame) between now and whenever the airframe is up for consideration of a re-engine.

That said, the statement wasn't focused on just a 787 per se. This is a huge opportunity for PW to make a (final) bid for the MOM/NMA.

Is there a ballpark figure for what airlines could expect for compensation each day a frame is grounded?

A less hysterical read of the situation
https://www.flightglobal.com/news/artic ... -i-457105/

RR is already testing an enhanced HPT blade to increase durability. Their statement seems to imply that the working environment on the 787-10 is causing premature wear. That would seem to be an indication that the engine is being worked harder on the 78K and some weakness has shown up.

The B78X gets the high thrust variant of the engine and this premature wear to the HPT can be related with this... Lets see the results to the inspections of the B789

Guess now we know why RR didn't want to participate in more engines for EK A380 or bid for NMA/MOM project. They need to get their house in order first. Seems like PW and RR are having mid life crisis, let's hope GE doesn't screw up.

Somehow I doubt SQ is likely to order the Ultrafan on a promised NEO A350 anytime soon in that program, once launched/as promised (for 2025).

Probably not much, as they can get a 787 with GE engines.

RR had a lot of opportunities over the past few years to figure this out. Disappointing that they had given an impression that the TEN was going to fix the T1000 problems but this happens.

Yet the thread starter's article says:

"All of these engine inspections on SIA's 787-10 fleet have now been completed, and a remaining check will be completed on a Scoot 787-9 by April 3.

"Pending engine replacements, two SIA 787-10 aircraft have been removed from service."

So as of five hours ago, only two 78X are grounded.

I'm sure that's very inconvenient for SQ and it's also worrysome for RR.

It seems like decreased inspection intervals are a likely outcome.

The FG article says:

In response to an query from FlightGlobal, the engine maker said that it has told operators that HPT blades in Trent 1000 TEN engines would have a limited life cycle, and that it has sampled a “small population” of the engine fleet that has “flown in more arduous conditions.”

R-R adds that it is working on a fix for the wear issue.

“This work has shown that a small number of these engines need to have their blades replaced earlier than scheduled. In anticipation of limited turbine blade life, our engineers have already developed and are testing an enhanced version of this blade,” it adds.

More overtime for my cousin in Derby UK, so it seems.

IMHO Aircraft Manufacturers may streamline the EIS for a particular model by limiting the NUMBER OF CHOICES in the components, however it shows how this can be a liability for them as well. They may want to consider a procurement process that includes 2 or more choices for the buyer.

Agreed. Took the words right out of my mouth.

I've also been wondering for some time now when airline customers would get to the point where they would simply wash their hands of RR and not take the risk. Now we've got to be getting to the point where A and B are reaching the same conclusion. It's simply not worth the risk. The costs are too great and the stakes are too high.

Well...... their subsidiary scoot’s 20 787s are already in rr engine troubles. Having 9 wide-body made unreliable will indeed give SQ itself a lot of trouble. Hopefully they can find a way to resolve this.

Why?

They have the Trent XWB in service and running reliably. Same with the Trent 900, Trent 800 and Trent 700. The XWB is powering the longest commercial flights in the world at the moment.

So a couple of engines on a high-duty airframe are showing premature wear and you think a large commercial co-operation such as SQ and RR operate should be dumped?

There have not been any incidents. This is proactive maintenance. Better to ground and fix than let it go bang in the air.

Airbus is pretty much all in with RR on the WB lines. I don't know that hoping RR gets their stuff together is a solid business model, but they certainly need to get kissy face with PW on a bigger GTF.

The Trent 1000 is currently running at IFSD of about 0.2/100,000 hours (pretty similar to the GEnx), the GTF is running at 1/100,000 hours - five times worse and at the ETOPS<180 limit - why exactly do Airbus need to get into bed (or kissy face) with PW with a larger GTF?

Could this mean that the engine in question is not really suitable for multiple short flights every day in tropical conditions - which is what SQ bought these aircraft for...?

SQ should use two sample aircraft on long flights for six months to see if cracks happen then as well.

Their first 787-10 flight from HKG had to return to the gate because of engine issue,
Which resulted in a few hours delay of the flight.

The original issue was Sulfidation Corrosion in the Intermediate Pressure Turbine which RR pointed to being due to the higher particulate pollution levels in many Asian cities the affected engines operated into and out of.

I am guessing RR is now seeing it in the High-Pressure Turbine. Interesting that has now migrated to the HPT - did RR make changes to the airflow of the TEN that allowed this to migrate from the IPT to the HPT?

In theory, the 787-9 should be as susceptible as the 787-10 since it is an engine issue, not an airframe issue.

Well the 787-9 and 787-10 should be available with the same thrust options. I'm going to guess that RR is again pointing to what they claim is higher sulfur air pollution levels in Southeast Asia and China contributing to the increased Sulfidation Corrosion they saw first in the IPT and now the HPT. The resolution for the IPT was a new alloy / coating so I expect they will port this to the HPT now, as well.

Sheesh, come on RR. I wonder if GE has been quietly working on a solid PIP for the GEnx while RR continues to fumble around with the T1000? A CMC package for the engine could be enough to sway future engine decisions.

Why didn't RR find these problems in testing or development ? Seems to me some engineers under pressure to try to keep costs down, but hurt the company with many millions in costs to fix now.

RR has alluded to a belief that the cause is poorer air quality in SE Asia and China compared to North America and the EU where I expect the majority of the testing would have been performed.

It's one thing to add a coating on an IPT, but the HPT is the most intense part of the engine and is where engine manufacturers try to extract every bit of margin. If they could have added a coating to extract more margin, they would have done it from the start.

One short-term option is to derate the RR powered B787-10 to increase durability, it should still leave plenty of range for most of SQ's intra-Asia flying.


Someone mentionning a PIP with CMC on the GEnx.
The CMC technology is promising but not game-changing enough yet, not proven and not possible to integrate without major modifications to entire turbine spools.
The in-service Leap only has stationary shrouds made out of CMC and they have already experienced issues, so imagine how difficult this becomes with dynamic/rotating parts.
CMC is already testing on the GEnx serving as testbed for the GE9X, so when the time is ripe and if the ROI is justified, they should be integrated into the GEnx.

What I am suggesting is that RR is highlighting the kind of workload on the 78K. High thrust settings, longer times at TOT, limited or no derates. Work an engine hard and it wears out faster.

The Trent 1000 and GEnx were both built to be light and efficient. Both have had their problems. RR is probably learning (the hard way) just how far they can shave those margins. Rather than a coating issue in the HPT Rolls may well be looking at a materials tweak.

Probably not much, as they can get a 787 with GE engines.


And if they’ve already got 789’s with Rollers?

This must be concerning to all newer RR engines.

What airlines have TEN on their 787-9?
I know El Al had all their engines replaced to TEN

Not too hard to make a switch for any new orders.

This could possibly means their A333/B772/B772ER/B773 retirement will be pushed further backward. One could still recall remember they brought a mothballed B744 to cover for A380 grounding in 2011. Also an ex-MH 744 to cover for A380 delivery delay in 2007. Has technology gotten more unreliable nowadays? History repeating itself.

Why didn't RR find these problems in testing or development?


RR has alluded to a belief that the cause is poorer air quality in SE Asia and China compared to North America and the EU where I expect the majority of the testing would have been performed.

Perhaps, though one would wonder why VS were so significantly affected, considering how little time their 789s actually spend in Asia.

Same, but to a lesser extent, for BA.

Overall the "financial underperformance" attack on RR
by analyst that had zero inkling on how the jet engine place functioned
was super effective.
Start that in a window were RR already had technical issues and have it spiral
out control via the "any dumb management" solution to perceived bad financials:
reduce outlay, reduce workforce.

Perfectly managed echo chamber attack. GE in the background? Their Astro Turfers often worked overtime.

According to FR24 SCB and SCF are back into service so they must had their engines swaped.

Not a big deal. (depending on what deal they have; 'power by the hour' kind of stuff usually )
RR support is nearest in SIN
GE support is just across the ditch (QF and NZ have a long history
of mutual support in engineering and flt ops stuff. Being that QF is
a major carrier it's reasonable to expect GE will set up a real support spot in
SYD. Even more so if NZ were to get on board)
