Step 3: Using a unibit drill two 5/8" holes in the F-1006B Bulkhead according to the dimensions given in Figure 1.

Step 4: Remove the F-1006B and Deburr

Step 5:  Dimple (flush on the top side the four #40 nutplate attachment rivet holes in the small flange on the top of the F-1006B Bulkhead.

Step 6:  Dimple Flush on the forward side  the #40 holes along the top of edge of the F-1006B Bulkhead.

Step 7: Dimple three #40 holes in both theF-1006A and C Bulkheads for dimples on the F-1006B Bulkhead.

Step 8:  Dimple (flush on the forward side) the two #30 holes in the F-1006B Bulkhead and the underlying holes in the forward flanges of the F-1029 Bell crank Ribs.

Step 1;  Remove the F-1006B Bulkheads from the Tailcone and cleco it to the aft flanges of the F-1019, F-1020, and F-1021 Baggage Ribs. Do not cleco the bulkhead flange to the mid fuse skins.

Step 2:  Cleco the Tailcone skins to the mid fuse skins as shown in Figure 1. All of the mid fuse skins are clecoed outside of the tail skin cone. Notice the following. In the bottom blow-up the triangular portion of the F-1073-L Tailcone Skin slips between the F-1070-L Mid Side Skin and the F-10100A Baggage Door Shim. The holes in the mid side skin which are common to the baggage door shim are matched drilled into the Tailcone side skin in a later step.

In the middle blowup, the F-1006B Bulkhead and th3e F-1078 Tailcone Forward Bottom Skin are captured between the F-1019,-1020, and 1021 Baggage Ribs and the F-1077 Mid Bottom Skin.

Step 3: Final-Drill #30 the holes common to the aft flange of the F-1019, F-1020, and F-1021 Baggage Ribs and the F-1006B Bulkhead.

Step 4: the F-1046-R Mid Fuse Longerons fits on top of the F-1032-R Tailcone Longeron as shown in the top blow-up of Figure 1. Make sure the vertex of the two longerons are aligned, then clamp them together.

Match-Drill the four #30 holes in the aft end of the mid fuse Longeron into the Tailcone Longeron using a #30 drill, then final-drill #12.

 Drill and bolt the two aft most holes first, then Uncleco the upper portion of the F-1006C Bulkhead to gain access for drilling and bolting the two forward holes. Be careful to drill perpendicular to the longerons.

Page 32-4

Step 1: Make shims from some scrap .025" or ,032" aluminum sheet to fit between the F-1074 Tailcone Forward Top Skin and aft ends of the F-1046 Mid Fuselage Longerons as shown in the blow-up of Figure 1.

Step 2: Cleco the Tailcone Forward Top Skin to the tailcone as shown in Figure 1.

Step 3: Match-Drill #40 the holes of the F-1070-L Mid Side Skin and the three holes of the F-1074 Tailcone Forward Top Skin into the F-1046-L Mid Fuselage Longeron as shown in Figure 2. Have the shim made in Step 1, in place when drilling the three for the F-1046-R Mid Fuselage Longeron on the right side of the fuselage.

Step 4: As indicated in Figure 3, match drill #40 the six holes in the F-1070-L Mid Side Skin (aft  of the bottom edge  of the baggage door cut-out) into the F-1073-L Tailcone Side Skin. Be sure to drill perpendicular  to the skin since these holes are common to the preexisting holes in the F-1023-L Baggage Floor Angle and the F-10100A Baggage Door Shim

Machine Countersink these six holes in the mid side skin for heads of AN426AD3 rivets.

Step 5:  Final-Drill #40 the holes along the angled edge of the baggage door cut-out (see Figure 3) common to the F-1070-L Mid Side Skin and F-1073-L Tailcone Skin.

Step 6: Final-Drill #40 the holes common to all of the skins and F-1006A, B, C Bulkheads ( the F-1006B and C Bulkheads are not shown in Figure 3).

Step 7: Match-Drill #40 the row of holes along the aft edge of the F-1077 Mid Bottom Skin into the F-1078 Tailcone Forward Bottom Skin.

Step 8: Remove the F-1074 Tailcone Forward Top Skin. Machine countersink the holes in the F-1070-L and - R Mid Side Skins and F-1046-L and-R Mid Fuse Longerons as instructed in Figure 3.

Page 32-5

Step 1: Remove the tailcone from the mid fuselage and the F-1006 Bulkhead from the tailcone. Deburr the holes that have been drilled according to this section, and remove any chips from between the F-1070 Mid Side Skins and F-1046 Mid Fuse Longerons.

Step 2:  Dimple the holes in the skin flanges of the F-1006A, B,C, and D Bulkheads. Do not dimple the holes in the two tabs on both F-1006A and C bulkheads which back-up  the 1032 and F-1046 Longerons.

Step 3: In all of the Skins, dimple the holes which are common to the flanges of the F-1006A, B, C, and D Bulkheads.

Step 4:  Dimple the aft most row of holes in the F-1077 Mid Bottom Skin (See Figure 2) and the corresponding holes in the F-1078 Tailcone Forward Bottom Skin.

Step 5:  Dimple the ten holes along the top edge of the triangular, projected portion of the F-1073-L Tailcone Side Skin (see Figure 1). Dimple the corresponding holes in the F-1070-L Mid Side Skin.

Step 6: Dimple the three holes in both sides of the F-1074 Tailcone Forward Skin (see Page33-4, Figure 3) which are common to the F-1046 Mid Fuse Longerons.

Step 7:  If not already done, set rivet in the six indicated holes (see Figure !) in the F-1078 Tailcone Forward Bottom Skin, the F-1029 Bell crank Ribs, and F-1047 Stiffeners using rivets called out.

Step 8:  Rivet the two nutplates to the small flange of the F-1006B Bulkhead using the rivets called out in Figure 1.

Step 9:  Rivet the F-1006B Bulkhead to the F-1006A and C Bulkheads using the rivets called out in Figure 1.

Step 10:  Rivet the F-1006B Bulkhead to the F-1029 Bellcrank Ribs using the rivets called-out in Figure 1.

Step 11: Cleco the tailcone to the mid fuselage then bolt the F-10046 Mid Fuse Longerons using the same hardware as before.

NOTE THE F-1074 TAILCONE FORWARD TOP SKIN IS RIVETED AFTER THE UPPER CABIN IS INSTALLED IN A LATER SECTION

Step 12 Rivet the skins to the F-1006A, B and C Bulkheads. As indicated in Figure 2, do not set the three rivets at the top of the F-1070-L and-R Mid Side Skins which are common to the F-1074 Tailcone Forward Top Skin.

Step 13: Set the rivets in the row of holes along the aft edge of the F-1077 Mid Bottom Skin.

Step 14: Finish riveting the aft portion of the F-1077 Mid Bottom Skin to the F-1019,-1020, and -1021 Baggage Ribs.

Step 15: Rivet the F-1070-L Mid Side Skin to the F-10100A Baggage Door Shim and F-1023-L Baggage Floor Angle.

Step 16: Rivet the F-1070-L and -R Mid Side Skins to the F-1046-L and-R Mid Fuse Longerons respectively. Again as indicated in Figure 2, do not set any rivets in the holes which are common to the F-1074 Tail Cone Forward Top Skin.

Step 17: Rivet the F-1019,-1020, and -1021 Baggage Ribs to the F-1006B Bulkhead using the rivets called out in Figure 3.

Step 18: Install the two snap bushings called-out in Figure 3.
