KC-135 CFM56 Engine Conversions

Thu Dec 07, 2006 8:23 am

Anyone know where I can get an up to date list of the C-135s and KC-135s that have been converted to CFM56 engines. I have the lists in a couple of KC-135 books but there have been more converted since the books were published.

You might try going to the Boeing web page and finding the e-mail address for the company historian. If he doesn't have the information, he might be able to point you to the person who would have it. Incidentally, he's a nice guy, so please be courteous.

What about http://www.planelist.net/boeing-707.zip ... pretty detailed information on all KC-135 ever built.

The USAF designation of the CFM-56 engine is the F-108. There are no USAF C-135s that have been reengined with the F-108s, only the KC-135 and several RC-135s, as well as the 11 remaining French C-135FRs and the TAF and Singapore AF KC-135Rs. The USN flys the F-108 on their E-6Bs, the RSAF has them on all of their E/KE-3s, the French on their E-3Fs, and the RAF on their E-3Gs. The F-108 also flys on the USN and USAF C-40A/B/Cs, as well as the RAAF, TAF, and RoKAF Wedgetails. The French also had CFM-56s on their A-340-300 and they had them on their one DC-8-55 (which is now retired, IIRC).

At the moment I cannot remember any other military aircraft that flys the F-108/CFM-56 engine.

Did the USAF field the intermediate level maintenance for the F-108? or is it all done at Tinker wit ha little 2 - level maintenance done in the field? I was reading aobut some of the problems with commercial version with bearings and such and I was wondering if the field can change bearings and cores , etx. or does that kind of maintenance have to go back to Tinker?

Most maintenance on the F-108 engines is done at the base level, including replacing bearings. Intermediate and depot level maintenance is done at Tinker AFB, OK

The French AF has A342s, not A343s. Also, make that DC-8-72 Combi. IIRC they had two. Aren't these now with ATI? The -55 had the standard JT3Ds.
Exceptions confirm the rule.

Hey Top, Do they do the C-checks at both Tinker and Kelly aviation? I was down at Lackland back in March, and they had a crap load of KC-10s, 135s and C-17s all there for either C-check or GRIP(C-17). Or is Tinker just the main ALC for parts-to include engines?

You are right, it is an A-342. But, France also did have a re-engined DC-8-55, the French President flew to PSM in 1988. I believe it was the only -55 ever converted, and it had an APU installed in the aft left wing root, too.

Yes, both Tinker and Kelly do "C" and "D" check equivelents. But, IIRC, only Tinker refurbishes the USAF and USN F-108 engines.
