Any G650 operators seeing "smoking" (i.e. they leave a dark trail on the fuselage) rivets on the fuselage at various locations?

    $\begingroup$ Welcome to the site @Dak2Boe. Unfortunately your question isn't very clear, what are smoking rivets and why do you think they are being seen? Is it a news article, or another source? $\endgroup$

    $\begingroup$ Do you have any photos or specific locations on the A/C where this happens? $\endgroup$ Commented Jan 22, 2019 at 12:54

All rivets that are properly set will eventually "smoke" given a structure subjected to vibration that has been under-engineered, meaning not enough rivets per inch. The other cause would be improperly installed rivets. What looks like smoke is aluminum oxide produced by the movement of the surface, and the rivet rubbing a bit of it and sloughing it out and back along the airstream direction.
