Vans Aircraft RV-12 Airplane Build, Sections 25: Tailcone Attachment (part 3)

Reference: pages 25-04; 4.5 hours

There has been a new revision (REV 1) to the RV-12 plans for this section which shows the wing fuselage doublers on the sides. I have already added these doublers per the service bulletin.

Step 1: Rivet the F-1284-L & -R Shear Clips to the F-1207C-L & -R Baggage Bulkheads as shown in Figure 1.

Step 2: Cleco the F-1273-L & -R Baggage Corner Skin in place. Underlap the F-1270-L & -R Left and Right Side Skins, F-1270A & F-1270B Side Skin Doublers and F-1276 Bottom Skins. Overlap the Tailcone Assembly skins as shown in Figure 1 and 2.

NOTE: The clecos in the F-1273-L & -R Baggage Corner Skins that are called out in Figure 2 mark holes that will be left open in this section.

Step 3: Rivet the Tailcone Assembly skins, the holes common to the Tailcone and Fuselage Assembly and the F-1273-L & -R Baggage Corner Skins using rivets called out in Figure 2. Rivets on the right side are a mirror of the left.Omit the holes covered by tape. Rivet the holes common to the F-1270-L & -R Skins, F-1280A & F-1270B Side Skin Doublers and F-1273-L & -R Baggage Corner Skins as shown in Figure 2. Remove the tape that was applied earlier in this section.

Today's work period ended abruptly when my Rivet puller died:( It has done a great job through both the RV-10 and RV-12. I tried replacing the seals again but the cylinder was scored and it just leaked fluid all over the place. Oh well until next time.
