Folks, this is the Amazon fleet thread. Please try to keep on subject.
On the previous page of the thread, we kind of had a question for you. There was a discussion about whether the CF6-80A fleet -- the engines used on the ABX/ATI 767-200 freighters -- were aging enough and/or become scarce enough that those aircraft might suffer the fate of, say, DL's MD80s in the near future, either due to engine reliability or availability of parts or expense of engine overhaul. One of the regular contributors to the thread pointed out that 21Air, for example, was having engine issues on both of its 767-200 aircraft, which were both fresh out of C-check, and one was grounded for about a week for engine problems right after 21Air took over the Aeromex work from ABX. I pointed out that the in-service fleet of 767-200s worldwide now numbers about 70, and 12 of the ABX/ATI 767-200s still had 5 years left on their dry-leases to Amazon. I thought that DL was doing the overhaul work on the ABX/ATI CF6-80As, which one of the DL mech's confirmed in a later post, also mentioning that DL did the overhauls on ABX -80C2s. So although clearly the long-time (and highly-regarded) engine service provider to ATSG will do (and is doing) overhauls for them, at one point does an overhaul become uneconomical, either because it becomes too expensive and/or a full overhaul is going to produce an engine that has far more time available than will be appropriate for the expected useful life of the airframe, without a sufficient secondary market for that engine if it outlasts the airframe (i.e. nobody's going to want that engine, with its time left, after you put the airframe out to pasture)? That's a lot of questions in one, but I figure that you're the guy to give us some perspective on it if you're willing. As I told the DL mech, I don't have enough understanding of the "levels" of overhaul to know whether you can basically overhaul it enough to get you 5 more years, for example, without having to completely overhaul it.
I might not even be asking the right questions, so we would appreciate your perspective.
