    Service Bulletin

    Service Bulletin link from Vans

    This service bulletin addresses cracks forming on the bottom skin of the tail, and the adjoining J-stiffeners attached inside. Since the tail was still detached from the forward fuselage, I figured it would be easy enough to just install the kit and not have it on the condition inspection checklist. Overall, it was relatively straightforward although crawling inside the tail to rivet the new brackets proved to be quite difficult, as the location literally required someone to crawl inside the tailcone. The resulting reinforcement plate on the exterior I decided to prime the contact patch since all external surfaces are currently unprimed.


  • 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.
