Service Bulletin


  • Inboard aileron hinge brackets
    Section 15 Service Bulletin
    Dec 12, 2020

    While not immediately obvious when starting the aileron hinge brackets I found that the parts were missing from my inventory for the inboard brackets. After digging a bit, I found that my kit included the service bulletin 16-03-28 subkit that address potential cracking problems with the original brackets. The new brackets are considerably heavier with a piece of angle aluminum instead of a folded flange, as well as two doublers with their own flanges on the backside.
