Hi
My S2L was built in the 90’s. When i bought it recently I decided to completely refurbish the aircraft.
I opened the wings to do a thorough inspection and to check if the upgrade had been installed.
So, the top skins are riveted with solid rivets, while the bottom skins had pop rivets. What i found was that there are micro cracks around the dimpled holes of the ribs. My guess is that the holes wasn’t properly deburred when dimpled. Also, the solid rivets of the top skins wasn’t properly set, so i am working my way through the wings and resetting all the solid rivets of the skins to have the correct amount of deformation.
The question now: does this micro cracks have a major effect on the structural integrity of the wings or any other associated risks? If so it will basically mean i have to build new wings.
I thoroughly checked the main spar and it rivets and all are in good shape.
Regards
Jacques
