Are these rivets smoking (loosening up)?

Or is it just some dirt streaking around the rivet?

Looks like loose rivets.

The only way to confirm if loose is to look at the back side of the rivets. However, given the aircraft and the area appears not to be painted, my first guess would be polishing compound residue streaking back.

Looks fine to me.

Leading edges on airliners are stainless steel, not aluminum. Most likely those fasteners are Hi-Locks, not rivets.

Not familiar with current aerospace manufacturing techniques I looked up High-Loks. For those inclined:

Corrosion resistant materials being applied too heavily will result in

“ smoke” as well. Since there is less friction in the skin lap I’ve

pondered whether the structural strength is also reduced. As the fastener/

hole wears there can be more movement before the fastener makes contact

to stop the movement. I doubt an oily substance helps here. Any

references?
