802N-1 Fwd Upper Brace (See “Fwd Fuselage Substructure”, DWG 63). Final-Drill #30, the 1/8 holes common
between the forward baggage bulkheads and the forward upper brace. Uncleco the fwd baggage bulkheads.
Deburr the screw holes, and all the final-drilled holes in the parts depicted in the “Fwd Baggage Floor
Assembly”, DWG 63, the F-866A-1 Lower Fwd Baggage Bulkhead, F-866B-1 Upper Fwd Baggage Bulkhead, F-
866D Mounting Plate, and F-802N-1 Fwd Upper Brace.

countersink the three mounting plate attach holes at the bottom of the F-866A-1 Lower Fwd Baggage Bulkhead,
for flush rivet heads on the forward side.
Dimple countersink all of the nutplate attach rivet holes in the F-866A-1 Lower Fwd Baggage Bulkhead, the F-
870C-1 Inboard Stiffener and the F-870B-outboard Stiffener. Refer to DWG 63 to determine which side of the
parts the nutplates will be mounted.
Dimple countersink all the #40 rivet holes in all the Fwd Baggage Floor parts depicted in the “Fwd Baggage
Floor Assembly”, DWG 63, for flush rivet heads on the upper side.
Prime all parts if/as desired.

Stiffener, F-870B-1 Outboard Stiffener and the bottom edge of the F-866A-1 Lower Fwd Baggage Bulkhead.
Back rivet, the two F-870D-1 Stiffeners, and the F-870C-1 Inbd Stiffener to the F-870-1 Fwd Baggage Floor
(See “Fwd Baggage Floor Assembly”, DWG 63).

802N-1 Fwd Upper Brace.
NOTE: Riveting will be delayed until later, to allow removal for improved rivet
access when riveting the forward fuselage side skins to the forward L.G. Box Bulkhead Assemblies.

Final-Drill #30 the 1/8 holes common between the F-822-1 Forward Floor Panel and the F-801D Lower Angle of
the Firewall Assembly. Remove the Firewall Assembly and deburr the holes drilled in this step.
Machine countersink nine holes in the center of the bottom flange of F-801D-1 Lower Angle (See “Exploded Iso
View Aft”, DWG 60). Dimple countersink the holes in the F-822-1 Fwd Floor Panel that are common with the
nine holes in the lower angle that were machine countersunk in this step.
Apply a thin layer of Fuel Tank Sealant to the surface of the Fwd Floor Assembly that contacts the F-801D-1
Lower Angle of the Firewall Assembly to prevent any wayward engine compartment oil from seeping into the
cockpit area. Only apply sealant in the center / cooling air ramp area where the holes were dimple-countersunk
in the previous step. The rest of the Firewall perimeter will be sealed when the remaining skins are installed.
Re-cleco the Firewall Assembly in place on the Fwd Floor Assembly.
Rivet the (
AN470 rivet locations only
) Firewall Assembly to the Fwd Floor Assembly. Refer to the “Fwd
Fuselage Sub Structure”, DWG 63 for rivet callouts and a depiction of the nine rivet holes that need to be
clecoed but not riveted at this time.
Cleco the Fwd Baggage Floor Assembly to the F-866A-1 Lower Fwd Baggage Bulkhead, F-871-1 Fwd
Baggage Side and the Firewall Assembly using 1/8 clecos.

Bulkhead, between the holes, to make them straight and flat. Deburr the edges of both bulkhead parts (DWG
63A).
Separate the F-870B-1 Outboard Stiffener from the F-870E-1 Skin Stiffener (See “Separating F-870BE”, DWG
63A). Mark the F-870B-1 and F-870E-1 stiffeners with their name and part numbers to make them identifiable
later in the fuselage construction.
Separate the two F-870D-1 Stiffeners from each other and from the F-870C-1 Inbd Stiffener (See “Separating
F-870CD”, DWG 63). Cut the taper on the two stiffeners by trimming as shown in Detail A.
Deburr the edges of the stiffeners from the two previous steps.
Cleco the two F-870D-1 Stiffeners, and the F-870C-1 Inboard Stiffener to the F-870-1 Fwd Baggage Floor (See
“Fwd Baggage Floor Assembly”, DWG 63A). Final-Drill #40, all the 3/32 holes common between the stiffeners
and the Fwd Baggage Floor
Final-Drill the 3/32 nutplate attachment holes in the F-870C-1 Inboard Stiffener, the F-870B-1 Outboard
