Anybody know what kind of engine hangs on the wings of the JAL 744s? I'm hearing rumblings of DL being interested in picking up a few from JAL as they park their fleet.

I THINK they use General Electric. Don't quote me on that though.

Correct. The JAL 744s have GE CF6s.

Interesting... what about the 777s? THe rumbling I've heard hasn't exactly been a/c specific, but I assumed it was the 744 since JAL is indeed parking them and that the DL training facility in MSP will be getting ANOTHER 744 simulator.

Boeing shows all JL 744s with GE engines. Their 741/742/743s were all PW.

After the 1985 crash of 747SR with Pratt engines JAL has purchased GE 744's. Some 777-200 may also have the GE90 engine as do the 777-300ER's.

The domestic 772As and 773s are PW because they were the lightest of the 3 engines. The 772ERs are GE90s, as are the 77Ws.

That seems like a strange reason since that crash had nothing to do with the engines.

I really doubt the crash of JL123 led to the decision to use CF6s for their B744s.

JAL felt at the time Boeing and Pratt & Whitney didn't do enough to fix the rear bulkhead of the crashed 747SR, over 500 people died. The passenger knew they had 20 minutes until they died and all kinds of letter and notes were found at the crash sight. I believe the fix left teh pilots unable to control the airplane.

Why would Pratt have anything to do with the rear bulkhead? IIRC it was a bad repair job on the rear bulkhead that brought the plane down nothing to do with the engines.

777-200s are PW4074 or PW4077 depending on delivery date. 777-200ERs are GE90-94Bs.

767-300s are a PW/GE mix and 767-300ERs are all CF6-80.

Quoting Jfk777 (Reply 9):

The loss of the vertical stab was the reason they couldn't control the airplane. The pressure bulkhead repair was faulty but it was also JAL engineers' fault for not finding further damage or properly inspecting the repair when the aircraft was returned from the manufacturer.

As much as I'd like to see it, I wouldn't think DL would be that interested for two reasons. First is the GE engines, and second is the age in most of the JL fleet. Only about 10 JL PAX 744s are younger than 1994. DL has an aging 744 fleet already.

But, DL has done stranger things.

Rumors abound...and are on the line coming from various sources. This is what I have heard:

-DAL to take over JAL routes North America to Asia.
-DAL to acquire JAL MD-90
-DAL to acquire some of JAL's 747s
-DAL to transfer some JFK flying (due to runway construction) to DTW
-DAL to fly DTW-GRU

Of course, you believe these when the company confirms, but those are a few of what I am hearing.

Interesting.

- I think the DL acquiring JL's MD90 fleet is a given.
- I am a little surprised that DL would be interested in JL's 744s, however if they are taking over JL's N.American routes I suppose it makes sense. (still surprised JL would pull out entirely)
- I saw the DTW-GRU rumor on this board elsewhere and it didn't make a lot of sense to me, but combining it with these other developments makes more sense. Allows JL to still connect Tokyo and Sao Paulo with 1-stop, and between the JL feed from Japan and DL domestic feed I suppose that would probably work.

if you pay the OEM to carry out an approved repair, you expect the OEM to do it correctly , which B did not. plus how easy is it to inspect the bulkhead??


the reason JL went with GE was because of surge issues with the Pratts and the horrible PW backup. same reason CI dumped Pratt for GE on all their freighters and their last few pax 744s. bad customer service sends your previously good customers to the opposition especially when they can get great financial deals and the heck with commonality with the rest of the fleet

Nonsense - when you have car work done, you have them show you that everything is in working order. When someone comes to my house to repair something, I ask for a demonstration of everything being in proper working order, OEM or not. When an airplane that belongs to you returns from major repairs, regardless of who did them, you have your own staff make sure everything is up to spec. Anything else is illogical.

Its more likely (if) that Delta goes after the ex SQ birds, much younger and have PWs. Boeing has 4 on its web site which would bring the DL fleet to 20. DL could get more as SQ parks them as needed.

JL-
1990-9
1991-4
1992-5
1993-2
1994-3
1998-3
1999-4
2000-2
2001-1

DL-
1989-6
1990-4
1999-4
2002-2

DL could replace the PW fleet and add 4 extra frames and have a(over all) younger 744 fleet. As said above though, i believe Delta would go after the exSQ birds, which are PWs and are newer.



yep.

Just because your car is working again does not mean they fixed it properly to last or you can tell they reassembled the tranny perfectly or the timing belt or seals are all perfectly in place. the plane did not fall apart the first few times it flew and neither would your car have not worked after you drove out the garage for the first few miles. AFAIK you could not inspect the bulkhead and see the non compliance with the repair manual, now if you think JL should have had a team of people looking over the shoulders of the Boeing people while they did the repair thats another issue. While it may, in hindsight, have been prudent for JL to have had more oversight of the repair, the fact is , very few airlines would question the OEM itself carrying out what the OEM says is the appropriate repair procedure, though as we now know they botched the job. If this was done by some 3rd party MRO there probably would have been more oversight.

Delta getting the MD-90's, sure no on else wants them.

DL getting some JAL 744's ? IF they dumped the whole NW fleet then perhaps they could have JAL GE powered 744 if they are in better shape, but what condition are the NW 744's in compared to JAL's ?

JAL's 777-300ER will fly to JFK daily, the Japanesse travel to New York a lot and want a Japanesse airline. The issue with teh runway being paved is a non-issue because JAL's main daily New York flight arrives before lunch and leaves ( in teh summer) at 1:30pm, well before the European rush. The other JFK flights may be cut since they are the ones going to Sao Paulo arriving and leaving during the JFK rush hour.

JAL flying to Dteroit and Atlanta should happen even if DL has to cut its self back to just one daily trip on each route as a gesture of goodwill to JAL and for JAL to expand beyond the JFK, ORD, LAZX and SFP gateways it has always flown to.

JAL just stopped Mexico City and they should stop the Brazil route its too far from Japan, the same reason most European airlines don't fly to Australia any more.

No they don't.....dude JL is loosing money, hand over fist, the best thing for them to do is park the 744s, have a few 77W/772s to fly routes that need F (LAX/JFK) and let Delta take over the rest/cut some routes(ORD, I don't think will stay around without AA.)
Also It isn't as cut and dry as those on a.net want to make it out to be. The DALPA and the JL union(s) will have to agree to some kind of deal, which will likely mean A) DLs gives up the intra-Asia routes that they can make work from the US B) nothing really changes.

JL will keep one flight to JFK and one to LAX. Outside of that, id say nothing is safe.

JL uses the GE CF6-80C2B1F Engines on their 744/744F. I believe these are the standard GE engines on most GE powered non-ER 747-400s. They're rated at ~58,090lbs static thrust.


We often judge others by their actions, but ourselves by our intentions.
25 LAXtoATL : It makes much more sense for JL to continue JFK and LAX service instead of DL taking over all N.American flying. Not only does it allow SkyTeam to ma
26 DeltaL1011man : We JL does have some 772As and 773As that they could replace, also JL will be dumping the 744Ds which will have to be replaced. I see DL/JL having 3x
27 NWADTWFA : The part about transferring flying from JFK to DTW wasn't in reference to JAL, but in general...the rumor was to DAL would transfer international fly
28 DeltaL1011man : This and there have been a few rumors of DL getting more 330s and or more 777s. All 2nd hand. Also something that has to be looked at is what happens
29 Airbuseric : So, we're talking here about JAL's B744 engine type isn't it? Question is answered ..., so further discussion about what DL , and DL, and DL will do
30 CokePopper : I am pretty sure the JFK summer schedule already reflects the planned construction. Nothing. As of May, All f/a's will fly all a/c. Just not mix form
