777 Powere Plant Transportation

My Corporation is planning to buy 777 (dont know further about the airframe or engine ) but have learnt that its engines are difficult to transport because of their large size. So much so that even 747 with side cargo door cant carry it due to the size of door and engine. Is it right ? If yes then how do airlines take care of it if they dont hv such provisions ? Similarly which a/c are capable to carry these huge engines ?

Thanx.

Most commonly the AN-124 is used to transport the engines for the 777.

I think a 747 can be used if it is loaded through the nose.

I don't know about P&W or RR, but the GE90 is designed so that the fan module is relatively easy to remove from the core engine for transport. With the engine split into two pieces, it can be transported on widebody freighters such as the A300F, MD-11F, 747F, etc. The fan module is placed on the aircraft on its side (so the diameter is now the width, length is now the height). If the fan module were not removed, the engine could be shipped as a whole on large transports such as the C-17, C-5, and An-124.

Aeroguy looks more reasonable to dismantle engine for transportation. But is this a normal practice ? I mean dismantling it for transportation and assembling it again. How do u get yr engines ?

Nose loading jumbo will not work. The area below the cockpit is much shorter that than main deck area.

Experience from an airline which operates both 772 and 773

The Roller will only fit into a nose cargo 747. Will not go into side cargo door.

Yes An124 is an option.

Remember thou If you op 777s chances are if you have to divert, make sure if you use a 747 with nose door, the airport has nose lift access. Many airports dont have this facility.( once had an A330 AOG in CNS. Had to fly engine to BNE then road transport to CNS )

Cathay. Lots of A330 and 777 experiance

What about external mount points to transport the engine like the B747/MD-11 and others have?

I don't think it's posssible to have such a big engine hanging on the wings on the B747! It's way to big.

When MH had a 772 down in Per in 2000, they sent down their B743Combi with the replacement engine inside. It came out the side cargo door. I apologise for not having them scanned. But I viewed this with my own two eyes, and trust me, they took a mightly long time to take the engine out.

Rolls Trent 700 @ 800 will not fit throu 747f side door.

Maybe Pratt of GE is smaller diameter.

GE90 can be split as mentioned earlier, but then takes a while to assemble;

FYI even rb211 nose cowl wont even fit throu lower cargo doors on 747

MH transported their 777 RR Trent Engine 890 using their B743Combi. How do you think they got the engine out? I'll try to source out the photo.

From reliable sourse at CX who witnessed this event of MH AOG.

With nose cowl removed and also tail section this engine did come out of side door.

Would like to know how much gap they had.Between door and engine.
