Well, for starters, things like cables and pulleys have to have inspection

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."

Maybe you need to read some more, like how you can tell there is corrosion
under the paint and maybe why there is very little aluminum to another
metal contact in airplane construction.

And, once again, that's what you pay a mechanic to look for.

Well, sure. I was only chatting here. Didn't claim to be an
expert. I know the paint may bubble. But worse would be
a hairline fracture within, or compromised rivets.

and maybe why there is very little aluminum to another
metal contact in airplane construction.

That was a hastily referenced link. I noticed after the fact
it was discussing contact with another metal. That isn't
a concern of mine. ( remember, I worked at Lockheed )

And, once again, that's what you pay a mechanic to look for.
