Does anyone have any idea what aircraft engines Delta currently overhauls and where they are done? Delta operates Pratt and Whitney P2000, Boeing 757, and P4000 engines, Boeing 747-400 and Airbus A330. It also has the CFM-56 engines which power their 737s and Airbus A319 and A320 aircraft. Then there are the 767, 777, and now the MD-90 aircraft. Of course the MD-80s and DC-9-50s have the JT8D series engines. Does Delta do overhaul maintenance on other airline' engines whether or not it is an engine that Delta operates?
Delta still has an engine shop at MSP, along with, I assume an engine shop in ATL.
Also, does Delta outsource any of it's engines for overhaul?

Quoting NWAROOSTER (Thread starter): Does Delta do overhaul maintenance on other airline' engines whether or not it is an engine that Delta operates?
Delta does lots of in-sourced engine work, but only on engines types they operate. I have not seen any numbers this year, but in 2010, approximately 40% of engines coming out of the shops were customer engines.
The engines overhauled in-house are:
PW JT8D-219
CFM 56-5 and -7
PW2000
PW4000
GE CF6-80A
GE CF6-80C3 B6F
GE CF-34 as used on the RJ.
The engines that are sent out are the Trent, GE90, V2500 and the GE CF6-80C3 B8F (767-400 engine). I honestly don't know where the PW JT8s are done for the remaining DC9 aircraft.

Quoting Deltal1011man (Reply 5): Yes. Its TechOps biggest money maker. Off the top of my head I can think of, HA, Atlas, GOL, AS, UPS, FX, AM and others.
In addition to the U.S. Navy's C-40s and some other foreign carriers.

Quoting Deltal1011man (Reply 5): Not sure if they have started doing there 2037s, 4000s, or JT8s
PW4056/4168 was brought back in house. Delta was trying to in source the PMNW PW2037 engines but I believe there were some contractual issues with PW that needed to be overcome first. Don't know where this stands now. I can't remember about the JT8Ds.

Quoting Deltal1011man (Reply 9): you know, I don't know if they do the engine overhauls(CFM56-7s) or not. I know they do air frame stuff.
That was going to be my question. I know they did A stuff for them including some form of their PSVs? Not sure if that included the powerplants. Maybe the military sends all their engines to the OEM.

Well that makes sense
Quoting FlyASAGuy2005 (Reply 10): So, DL TechOPS is the only MRO in the US that works on the these? Everyone sends them to either DL or outside the US? That's pretty cool..
And is almost certainly not true. There's no way that DL is the only maintainer of an American engine flown by the thousands in the US.
I can't prove it either way. But I'd like to see proof that its the case.

for a completely out of fleet engine too. From what I remember they pretty much do all the big RJ operators OHs.

.....not counting the OEM FWIW.
Ok a little bit of googling has brought me to this, http://www.mymroservices.com/mro_services_products/engines_cf34
It lists Delta TechOps and StandardAero as the only two in the US that does OHs on CF34 engines. (again not counting GE) ( Dallas Airmotive says in the remarks that they do OHs but going to there web site it doesn't list any certs for the CF34.)
Looking at SrandardAero web page it says they do the CF34 work in Winnipeg. So if that is true then so far it look like its just TechOps as the MRO. I will keep digging though.
and just for the record I can think of a few engines that don't(that I know of) have a MRO in the US. GE90 and V2500s both come to mind.(and yes I know they aren't as popular as the CF34....just pointing that out)

even though being able to go out to the Test cell and see something like a Trent 700(does anyone have any in the US?) or maybe something real odd like a Russian engine would be pretty cool.......burn money....but cool to see.

Quoting seabosdca (Reply 12): Why would that be? Those engines can't be very different. Is it a contractual thing?
The B8F engine is not just a data plug/software change from the B6F. DL sends them to Evergreen in Taiwan, I'm sure it was not worth the investment for a small subfleet of approx. 45 engines. It also looks like there is a contractural agreement as well.

Very interesting, I always thought the B6F and B8F were just a plug change and were very similar, thanks for bringing this to light.
How about overhauls for the B6 vs. the B6F? I'm referring to those CF6's on the ex-GF 767's which I think are non-FADEC. Surely that must be a small subfleet of engines as well.
I'd also be very curious to see where the JT8's on the DC-9's are done.

The JT8's were done in the old ATL Northwest Hangar, also MSP used to work on them, so I think if I remember correctly that work just all shifted up to MSP, but that was with NWA so Delta could have totally done something different.

I think the B6 is done in house. The main difference between the two is the mechanical connection from throttle to engine. I do know that there is a spare B6 engine for just those six airplanes.
Quoting MaddogJT8D (Reply 17): I'd also be very curious to see where the JT8's on the DC-9's are done.
I think that they are done in South America or AeroThrust in Florida.

I was just up in MSPs eng shop. ( not sure what the building number is, but I think it was C ) They are still running. They were doing build up on the V2500s that were arriving from overhaul, and Not sure what P/W 2000 work is done there, but they had one in the Test cell, when I was there.
Deltal1011man, Im with you. I just got back from RR school in Derby, and they had a Trent 800 in the Cell , and I would have loved to see that run. They also had a RB-211-524 off a 1011, but not in Running shape.

Thanks for that..that is pretty interesting. I remember back in high school I was in a science club and we took a field trip to Tech OPS and we went through the engine shop. They were running up a 757 engine in that huge engine bay. You could feel the steel doors vibrating the entire time and a slight his sound creeping through the cracks in the door seals. They also had some RJ engines on stands outside the bay being worked on.

When I worked at Northwest after the merger with Republic, I think the Republic engines were sent over to what became Building B where Northwest had a much larger engine shop. Delta has since torn down all the old Northwest hangers except for Hangers 6 and 7. Everything else that was north of the engine shop, including the stock room and what was called the "GO" or general offices has been gone for several years.
I am curious as to how much of what is left of the engine shop, welding shop and machine shop which have not be torn down is actually used. Building B, or what is left of it is immediately west of the rood leading into the Airport's Main Terminal. I have been hearing rumours that Delta is thinking about tearing down the old Northwest Hangers 6 and 7.
Hanger 7 was used for 747 heavy checks, while Hanger 6 was used for overnight checks and other maintenance on 747s and DC-10s, along with anything else that would fit in it.
The hangers and "GO" that were torn down was done to supposedly expand what was called the Gold Concourse. I do not know what they call it now. I personally think there was more to the reason given as to why these buildings were torn down.

Pratt would love every airline to do its own wrench turning, but to contract with it on an exclusive basis for the supply of new spare parts, used serviceable spare parts and part repairs.
Wrench turining is low margin work that only makes sense as a way to capture the lucrative parts and repair work.
