Baggage Door Support Strip.
Separate the two F-8104 Fwd Skin Support Ribs (See “F-8104 Fwd Skin Support Rib”, DWG 72).
Position the F-8104-L Forward Skin Support Rib against the F-821-1 Fwd Top Skin and WD-814 Windscreen
Support as shown in “Detail D”, DWG 72.
Mark the location of the P.P. holes in the F-821-1 Fwd Top Skin on flange of the F-8104-L Forward Skin Sup-
port Rib. Remove the rib and make sure that 3/32 holes ,drilled at the marks in the support rib, will have proper
edge distance. Make adjustments as necessary to the angle of the flange so it fits flush against the fwd top skin
and hole edge distance is maintained.
Match-Drill #40 the holes common between the F-821-1 Fwd Top Skin and the F-8104-L Forward Skin Support
Rib. Cleco as you drill.
NOTE: Do not drill the holes common to the WD-814 Windscreen Support at this
time.
Repeat the three previous steps for the F-8104-R Forward Skin Support Rib.
Uncleco and remove the F-821-1 Forward Top Skin.
NOTE: Label the outer surface of the F-821B-1 Aft Bag-
gage Door Support Strip and the F-821C-1 Forward Baggage Door Support Strip before removing them
to make it easier to later identify the correct surface for dimpling.
Final-Drill #40 the 3/32 holes along the left and right edges of the F-821-1 Forward Top Skin that are common
with the F-820-1 (RV-8) or F-891-1 (RV-8A) Forward Side Skins and the F-887-L-1 Upper Longerons.
Final-Drill #30 the 1/8 holes along the left edge of the F-821-1 Forward Top Skin that are common with the F-
820-L-1 (RV-8) or F-891-L-1 (RV-8A) Forward Side Skin, F-887-L-1 Upper longeron, and WD-802-L-1 Engine
Mount Bracket.
Deburr all the edges and rivet holes of the F-821-1 Forward Top Skin.
Dimple countersink all the #40 holes in the F-821-1 Forward Top Skin.
Dimple countersink the #30 holes along the left edge of the F-821-1 Forward Top Skin.
Deburr the #40 holes in the F-803C-1 Instrument Panel Attach Flange, F-866B-1 Upper Forward Baggage Bulk-
head, F-821B-1 Aft Baggage Door Support Strip, F-821C-1 Forward Baggage Door Support Strip, F-873G-1
Hinge Support, F-873H Spacer, F-8104 Support Ribs, and Firewall Assembly that are common with holes in the
F-821-1 Forward Top Skin.
Dimple countersink the #40 holes in the F-803C-1 Instrument Panel Attach Flange, F-866B-1 Upper Forward
Baggage Bulkhead, F-821B-1 Aft Baggage Door Support Strip, F-821C-1 Forward Baggage Door Support Strip,
, F-8104 Support Ribs, and Firewall Assembly.
Cleco the F-873H Spacer to the top of the F-873G-1 Hinge Support. Machine Countersink the F-873H.
NOTE:
Machine countersinking will slightly enlarge the holes in the spacer.
Prime all the parts from this section if/as desired.
Cleco the F-821B-1 Aft Baggage Door Support Strip, F-821C-1 Forward Baggage Door Support Strip, F-873G-1
Hinge Support, F-873H Spacer, and F-821-1 Forward Top Skin in place on the fuselage.
NOTE: Delay riveting the F-821-1 Forward Top Skin for as long as possible to provide improved access to
the interior of the fuselage for installing the instrument panel, electrical system, engine controls, etc. The
baggage door, canopy, and engine cowl installations can be mostly completed with the forward top skin
clecoed in place.
Rivet the F-8104 Forward Skin Support Ribs to the F-821-1 Fwd Top Skin (See “Exploded Iso View”, DWG 72).
Rivet the F-873G-1 Hinge Support to the Firewall Assembly and F-866B-1 Upper Forward Baggage Bulkhead
(See “Baggage Door Aft View, DWG 84).

intersects with the F-821-1 Forward Top Skin.
