this video gives some idea how far aircraft are stripped down on a regular basis - I've put it in here to give non-aviation people some idea of the
depth of maintenance that occurs, so they can stop with the "it's all hidden" nonsense.
A 3-C check like this might take 1-2 weeks elapsed time - at a small airline we used to take 2 weeks to do the equivalent on a 737, and they got 1
such check per 3000 flying hours - about every 13-14 months. I don't know what the interval is in an A380 - perhaps it is as long as every 2-3 years
as maintenance practices and aircraft reliability are so much better on more modern aircraft.
And of course between the major tear-downs the aircraft is also undergoing regular inspections, components are being replaced as their
overhaul/inspection/fine life comes due, etc.
