Step 01-A: Identify the Tailcone Skins.
The F-1278 Top Skin does not have a J-stiffener formed on either of the long edges.
The Upper Left and Right Side tailcone skins have a J-stiffener formed on one edge.
The left skin is mirrored by the right.

Tailcone Upper Skins

1 F-1278 Top Skin

1 F-1279-R Upper Skin Left

1 F-1279-R Upper Skin Right

Step 01-B: The Left & Right Side Skins have a J-stiffener formed on only one edge.

Tailcone Side Skins

1 F-1280-L Side Skin Left

1 F-1280-R Side Skin Right

Step 01-C: The F-1281-L & R Lower side skins have a J-stiffener formed on only one edge.
The F-1282-L Bottom Left Skin has J-stiffeners form on both of long edges.
The F-1282-R Bottom Right Skin has a J-stiffener formed on only one edge.

Tailcone Lower Skins

1 F-1281-L Lower Side Skin Left

1 F-1281-R Lower Side Skin Right

1 F-1282-L Bottom Skin Left

1 F-1282-R Bottom Skin Right

Builder Note: This step completed after Step:10-06-01

Step 02: Prepare the skins shown in Figure 1 for a lap joint by de-burring and breaking ( Section 5K ) the edges. The edges to be lap joints are called out in Figure 1. Both edges of the F-1278 Top skin must break in the same direction. The remaining skins must break in the same direction as the J-Stiffener. Begin with the F-1282-R Bottom Right skin, since it is least likely to be seen. when breaking the edges of the F-1278 Top Skin gradually increase the break angle toward the aft end.

Step 03: Flute the F-1210C Angle at the places called out in Figure 2. Each flute needs to 'hump' in the same direction as the five- hole flange. With the five hole flange pointing up, align the holes in the four-hole flange of the angle to the full scale illustration in Figure 2, Increase the two flutes until the five-hole flange matches the curve shown in Figure 2.

Step 04: Flute the F-1208-L & R, F-1209-L & R and F-1210A-L & R Fuselage Frames to align the flange holes. Flute the 'hump' of any humped flanges toward the web of each fuselage frame.

NOTE: The F-1208A Were Plate May be rotated 180º once prior to replacement.

Builder Note: Hold

Step 05: Rivet The F-1208A Wear Plate to the F-1208-R Fuselage Frame as shown in Figure 3.

Builder Note: Were plate on hold.
If this Plate is to be removed after wear the fasteners may be hard to drill out.

ALTERATION
Add nutplates to the back of the Wear Plate.

Step 06: Cleco, then rivet the F-1208-L to the F-1208-R. Cleco then rivet the F-1209-L to F-1209-R as shown, using rivets called out in Figure 3.

Hereafter, refer to the riveted F-1208-L & R as the F-1208 Frame and the F-1209-L & R as the F-1209 Frame.

Step 08: Match-Drill #30 the two holes from the F-1210A-L & R Fuselage Frames into the F-1210C Angle as called out in Figure 4.
Disassemble and deburr.
