But...I've had probably 10 ACNA's in my time at -28...Perhaps I'm just unlucky...I don't know.
That is a totally different issue, or can be. I think I had 5 ANA Canx in Dec as well, and that wasn't even a busy month. You don't necessarily have aircraft not available due to maint., it can just be because guys are bringing aircraft back late, or other issues. It can be maint, but not always. Also, the sheer number of aircraft in CNATRA is staggering. Not sure about Corpus, but at Whiting, there's at least 120 T-34s. Take about 40% (rough estimate on the contract, I'm not sure of the exact number), and that's 45-50-ish airplanes that have to be up. In a fleet squadron, you have a fraction of that available, and a fraction of that are actually up, and a fraction of that (and that fraction might be equal "0") may be FMC. Flash hit the nail on the head, TRAWING aircraft are much simpler to maintain, so that helps, too, but just the simple act of getting a part is generally easier for Trawings because of the money available. Need a new helmet? Okay, here's one. Try that in the fleet and it takes a minimum of a few days (generally).
Just putting things in perspective. Generally, as an end operator, Trawing aircraft availablility is a good thing.
