I am recovering my S1S and was told that there is an update to add a brace on the top of the cabane struts to tie them together. Looking through the picture gallery, i see several a/c have this brace tube so I looked on Aviat's website but couldn't find a service bulletin. Does anyone have the reference for this and/or the details of the tube used for the brace and installation location? I assume it is .035 4130 installed as high up the cabane's as possible...but you know what assume means...
Thanks
Brian
