Yeah, pretty much. Wing is one piece from wing root at fuselage to wing tip. Engines come off, everything else is riveted together. The tip tank, main tank (50 gallons), come off, then just the gear and access panels.
So basically you can’t un-rivet in places to remove part of the wing. So what happens if the wing is damaged from the nacelle outwards to the wing tip? Does the whole wing have to be replaced?
