That's what it looks like to me too. If it shows up, I usually remove it after conversion to JPEG (not really sure why, just always done it that way). Photoshop's CA removal tool is pretty good, and quite fine-tune-able. Should easily be able to remove the CA around the flaps.
I'd expect it to show more strongly around the runway lights, since that's a very high-contrast edge, but that's even well beyond what I'd expect!
What lens and at what aperture and focal length?
All other options exhausted, I'd do what Zak suggested. I'd probably try just desaturating the magenta color channel (and whatever other ones carry the aberration info). But whatever makes it look relatively natural.
Unfortunately, I don't think Photoshop lets you do selective CA correction, so that you could use different strengths on different parts of the photo. Not sure why not.
