SECTION 28: FWD FUSE RIBS, BHDS & BOTTOM SKIN

2023-02-14T23:06:18Z

EdHarris: Fixed typo on last edit, which concerned the rivets connecting the fwd fuselage bulkhead and the fwd seat supports.

Step 2 requires "Final-Drill #19, #30, and #40 all holes in the flanges of the attach angles that mate to the fwd fuselage ribs." and show the image of a nut plate on the flange that mates to the fwd fuselage rib. However, the kit does not have any provision for this nut plate in the attach angle, nor in the fwd fuselage rib (see photo)

Further searching on Vansairforce ([https://vansairforce.net/community/showthread.php?t=35821&highlight=28-2 link]) indicates that this nut plate was previously used to hold adel clamps for the fuel lines, but are not required in the newer kits.

Plans call for installation of the VA-188 Flo-Scan Mount Bracket to be installed in the tunnel location. This bracket is to be used for the Flo-Scan as well as for the FT-60 'Red Cube' fuel flow transducer. The positioning in the tunnel (between the electrical fuel pump and the engine-driven pump on the engine side of the firewall) is contrary to the installation instructions for the FT-60. See Vansairforce threads on this topic for alternative locations ([https://vansairforce.net/community/showthread.php?t=23682&highlight=fuel+flow+transducer link] and [https://vansairforce.net/community/showthread.php?t=11698 link]).

Step 6: On the version of the plans published 01/07/21 figure 1, there are three rivets called out to be countersunk for an AN426AD4 rivet - the top row of rivets attaching the forward seat supports to the fwd fuselage bulkhead. In fact, all four of the top row of rivets holding the forward seat supports should be countersunk. The F-01043D cover panel lays across all of those rivets and a universal head would cause a bulge. Verified w/ Vans Support 2/14/2023.

Step 10: The plans omit telling you to dimple the bottom flanges of the F-1048-L/R forward fuse ribs. Consider doing it at this step.

Step 5: On the version of the plans dated 01/07/21, the rivet callouts in figure 2 to attach the inboard and outboard forward seat supports to the fwd fuselage bulkhead don't add up to equal the number of holes joining the parts. The top row should be AN426AD4-5 qty 4 (NOT 6 + 6), and the bottom two rows should be AN470AD4-5 qty 8 (this is correct, albeit labelled poorly). The third row is left open to attach the fwd floor in a later chapter. Verified w/ Vans Support 2/14/2023.

Figure 2: Note that the 7 rivets on each side of the bottom skin must be double flush. This means you have to countersink the shop head side of the main spar so that when they are driven, the shop head sits flush into the spar. The landing gear steel piece sits on top of this area, and the shop head of the rivet will interfere with it if it's not flush.

SECTION 26: MID FUSE RIBS & BOTTOM SKINS

EdHarris: Added a note about the hole disparity on the step weldments.

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 [https://www.facebook.com/groups/vansrv10/posts/4880956025358791/ (FB Link 3/28/2022]) and [https://www.facebook.com/groups/vansrv10/posts/4891736740947386/ (FB Link 4/1/2022]) '''If your plans don't match what you have, check the electronic version of the plans which should show up under your name in the vans store.

Step 6 gotcha (Step 7 on V2 of 7/16/21 of the page): Plans call for 'Dimple the screw holes in the inboard flange of the seat rib intercostals that correspond to the flush nut plates...' Note that there are 3 nut plates on this flange, but only 2 of them are flush nut plates. The top nut plate is a K1000-08 and must not have its screw hole dimpled.

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. These dimples will match with dimples in the F-1070-L and -R Mid Side Skins (Section 29-17). The front flange of F-1015A is not riveted to the F-1004D-L/R Center Section Bulkhead at this time; that is done when the Mid Side Skins are attached.

Double check that the left and right WD-1008-L / WD-1008-R step weldment parts are labelled correctly by Vans. There are two reports of them being swapped.
See also [https://www.facebook.com/groups/vansrv10/posts/4902491573205236 FB Post 4/6/2022].

WD-1008-L / WD-1008-R step weldments have 16 holes each. The corresponding F-1021-L / F-1021-R outboard baggage ribs are missing four of these holes, with no instructions on the page to match drill. Vans support confirmed (12/15/2022 - Gary Keyser support engineer) that it is acceptable to match drill through the WD-1008 into the F-1021 and rivet. The plans corroborate this as they call out 32x AN470AD4-4 rivets.
