Thank you for sharing this @Claude Parent , I had no idea this could happen (especially at low airspeed). While we regularly check the rivets every preflight to make sure they're not loose, this one is entirely new... Though it's difficult to tell from the pics, was the hole possibly not deburred/chamfered to prevent stress risers or cracks from propagating? I regularly fly at higher airspeeds than most and I haven't found it necessary to install a trailing edge support but it may not be a bad idea.
