Well, for starters, things like cables and pulleys have to have inspection
plates just so you can inspect them.

I realize this. I fly Cessna airplanes, and am well aware
of where these access areas are.

Then why ask the question?

That's different from understanding what may be hidden
on an old metal plane I'm not familiar with.

That's what you pay a mechanic to look for.

I keep hearing about this with regard to old planes:

Aluminum corrosion.(under paint)

"Aluminum, however, is readily corroded when in contact with most
metals in a moist atmosphere due to its highly negative potential.
This type of corrosion is caused by a galvanic action in which the
moisture, acting as an electrolyte, causes current to flow through the
contact of the two metals while an electron transfer causes the
aluminum to go into solution."
