B767 RR Engine

Tue Mar 13, 2001 6:13 am

Why is the B767 market dominated with PW and GE engines?

I have seen BA and Southern China (not sure 100%) using RR engines on 767's. I always wondered why RR has not pushed more in selling their engines for this very succesful airplane type such as its sister ship 757.
Any reasons?

I do not know exactly but maybe it has to do with the fact that the airlines who have 767's with non RR have the rest of theri fleet dominated by GE and P-W engines so this would create a bigger maintenance job or it could deal with fuel efficiency

AFC you are right. That is understandable like in the case of United Airlines. Their fleet of 767 is PW equipped because almost all of their current planes use PW engines except the 737-300, 500. (I am not sure if they have -400) Airbus 320 too uses an engine built with PW cooperation (V2500)

How does engine comonality come into play with American Airlines? Their 767's are GE equiped, 757's are RR and now their 777's are RR equiped. Of course, they used 767's long time before 777's came in and their DC10 and MD11 used GE engines. Still, what I am trying to show is that there is no forced engine commonality in this airline. They use all Engine manufactures now. Why would not they opt for a RR engine on their 767 fleet?
There must be some other reason.

back again, maybe it could also have to do with cost or as i mentioned before fuel efficiency, maybe there is not much difference between the fuel factors of the GE , PW and RR engines but for a large fleet who fly alot, this could mean added costs for the airline

The RR engine was the last one certified for the 767, and only after British Airways made it a requirement for buying them. It is the heavest powerplant, requiring plyons changes which added weight. This weight comes from payload so I'm sure they suffer a slight reduction in payloads. It is also probably a little less efficient, as it produces the most thrust. It might make sense if you have a 747-400 RR fleet to go with the RR for the 767, but if not I doubt it does.

Anyone consider that the airline has some sort of direct relationship with the engine manufacturer, which would dictate the engine specified? The Business aspects are probably much deeper than us flyboys would consider. We're primarily interested in the iron.  Smile

Not only that, the RB211 that is offered on the 767 continues to have the durability/reliability issues that have made the PW and Ge the engines of choice for the 744's they with which they also compete.

The other airline to order the 763 with rollers was China Yunnan, although QF also now have 7 leased ex B.A machines.
In regards to engine choice I have no doubt B.A order theirs with R.R because of commonality with their 744's, however QF currently have all 3 available engines on their 767 fleet. The 762's have Pratts and the 763's have GE's on the ordered aircraft and RR on the leased ex BA aircraft, but even here there was or is engine commonality. The 762's were ordered when QF still had plenty of Pratt 747's although the newer 747's had RR. The GE 763's were a new engine type to
QF but they have since acquired and now ordered 744's with GE engines, while the RR 763's have commonality with the existing 744 fleet.

What I can derive from you guys is that airlines have different philosophies. United has Pratt relationship probably good prices on the engines and they will do anything to put Pratts on their planes.
Quantas on the other hand is more loose as to the engine philosophy so they slap on the wings anything that comes to their hand. As you say they operate all 3 engines on their 767's.

Also there is not many airlines that fly 747's RR equipped and also 767's that could be RR equipped. Correct me if I am wrong, but there is only handfull that do that. It is British, Quantas, South African. I think it is only these three that operate RR engines with exception of South African that operate GE or PW on their 767's. Well that explains also why not many airlines have 767's RR equipped because fof the fleet commonality.

What was strange to me was US Airways, they have the GE CF6 on their 767-200s and ordered the P&W 4000 series on their new A330-300s. Why didn't they order the GE CF6 series like Qantas did on the A330s where they can share the same spare engine parts.
