SECTION 26: MID FUSE RIBS & BOTTOM SKINS

PAGE 26-3

If you have part F-1016D (seatbelt strap) with an extra tab on the side and two additional holes but your manual depicts that part without flanges/extra holes, you are experiencing the transition from the old flap motor to the new flap motor where the tab is no longer needed. Your manual is a new version but Vans sent you the older part with the tab. According to Vans, just remove the tab and match drill the two extra holes and use same rivets as the other surrounding holes. For details, see this FB thread (FB Link 3/28/2022)

Consider at this point whether you need access holes in the F-1017 under-seat ribs for conduit and/or antenna wiring. Many builders cut holes in the F-1017 ribs for conduit passthroughs. These holes will be much easier to cut at this point.

Also consider marking and cutting/installing antenna doublers on the bottom skins in this general section. This will be much easier now than later, when the seat plates are permanently riveted in place.

If you haven't updated your plans in a while, ensure you dimple the #40 holes in the web of F-1015A. There was a revision on page 26-5 in July of 2021 that added this step.
