Santiago - A Boeing 787 of LATAM Chile is proving to be the most affected aircraft by the problems of Rolls-Royce Trent 1000 engines, needing urgent repairs. (airlinerwatch.com) さらに...
I would think if the wings were damaged they wouldn’t be safe to fly. And on the note other airlines aren’t saying anything about the wings being damaged at all just that the engines are having issues. Someone correct me if I’m wrong.
Haven’t followed this too much but I think the reference to the wings is to the engine pylons which if the engine vibrations were too great, it may affect the integrity of the wing pylon structure. We had vibration indicators on our RB 211’s which required a shutdown over a certain limit.
A couple of quick questions as you may be more knowledgeabale than some of the couch captains on this forum. How much of the wing is carbon fibre and is that the greater concern. Surely a metal pylon is replaceable but glued together CF is a whole new ball game. Second question is how does RR or Boeing retaian the 360 ETOPS for the aircraft if they have a known in flight vibration issue. Air New Zealand recently turned one around heading from Buenos Aires to Auckland. 13 hours over water with nearest divert Easter Island or turn back, depending on PNR.
No, the engines are having problems with the blades, which is increasing the vibration that is transmitted to the pylon. When the engine is unbalanced it vibrates more, and if it's more than the pylon was designed for, it eventually damages it.
It isn't necessarily dangerous to fly them on an empty ferry flight, because they use lower power levels. But it could become dangerous to keep flying heavy flights.
The Latam 787 stored at VCV is CC-BBD no CC-BDD. Just a 4 year old airframe hopefully they get this sorted out quickly as I'm sure that Boeing and RR are footing the bill for storage and loss of use.
from a news reportThe engine maker is designing a new intermediate pressure compressor (IPC) blade for Trent 1000 engines in the Package C configuration. The IPC blades came under scrutiny some 15 months ago after an engine failure on board a Scoot 787-9. Singapore's Transport Safety investigation Bureau found that two other shutdowns on Scoot 787-9s were linked to IPC failures probably caused by material fatigue.
Rolls-Royce has also, since 2016, been replacing the blades in the intermediate pressure turbine (IPT) module of the Trent 1000 after All Nippon Airways reported a series of engine failures. The engine maker traced the cause of that problem back to sulphidation corrosion cracking from a RR engineer friend of mine; RR trying to make the Trent 1000 more efficient and handle the additional power (electric) of the Boeing 787- Dreamliner changed their traditional engine design so the IP would be providing more power.sulphidation corrosion Probably from too much salty air
From what I've heard, they coated the blades after drilling the cooling vent holes into them. When they coated them, they were plugged, or partially plugged which let the blades overheat and suffer damage.
I think there are some significant differences here. The issue you are referring to requires an engine swing. Something LATAM would do and have done many times before in their own maintenance bases. You do not fly your four old machine to the breakers yard to change an engine. There is a lot more going on here behind the scenes.
They didn't fly them to Victorville to change an engine. There's a Boeing facility there that is inspecting the wings due to damage found caused by engine vibration. After the inspection, Boeing will perform the repairs.
Back in the 90's and forward the 757 with Rolls engines were the preferred ones (43,000 thrust). The Trent may just have some sorting out to do. When the RB211 first came out it was a 75 hour TBO engine. Jets are complicated.
No you are correct. It is so sad to see a storied component of the Jumbo Jet age having all of these seemingly endless problems. The truth even hurts the press. Rolls Royce employees are carefully trained and indoctrinated into the way of Rolls Royce. I am sure they will persevere because of nearly 100 years in aviation. I want to wish the Rolls Royce employees the best of luck in these times.
Ask British Airways about that! They may beg to differ, one of their GE equipped B777s aborted takeoff out of KLAS when the #1 engine blew up, caught fire and had a full evac on the runway. Not a pretty sight a couple of years ago. After almost 6 months they repaired the aircraft put a free GE engine back on, re-painted the aircraft and it's in revenue service as we speak!!
Good comment and I am glad I kept on reading the previous comments. All the manufacturers provide reliable products and one obviously will favour one above the other. Similar bias exists with e.g. mobile phones or cars.
Shouldn't the header read more sensibly [and fairly] - LATAM Chiles Boeing 787's in trouble with their Rolls Royce engines. As far as I'm aware, it's not the aircraft thats at fault, its the engines!
Certainly you must see the fault in that logic? At least as far as the general flying public is concerned. After all, what good is an aircraft without its engines?
So....who's responsible for the problems with Boeings Rolls-Royce engines. Sounds strange to me, that with the thousands of 787s flying...Chile, who's in Frances back pocket, is having problems with BOEING's Rolls-Royce Trent engines...
Don’t worry, there are also problems with P & W engined A320 Neos!! Lots of aborted takeoffs and in-flight shutdowns. So much so that the European EASA has issued an AD for those. Equal opportunity problems........
Living in Chile, and flying almost pretty often LATAM, I would be pleased to know.
