I am building the newer post SB-18-02-02 stabilator so pictures and knowledge of this redesign are limited. I am at the point of riveting the hinge brackets to the forward spar and, I believe I am reading it correctly, they are installed using LP4-3 pop rivets. I find this odd because it does not follow Van's prior pattern of using squeeze rivets in critical areas when able. I thought I would ask because it certainly is a highly critical component and squeeze rivets would actually install easier than pop rivets. Perhaps I am wrong but assumed squeeze rivets were a more robust choice particularly in a tension load such as this. I can see that the load is now also transferred vertically to the spar flange and skins so perhaps this is the reason for the pop rivet option.
