===== Countersinking F-01004C-L/R ===== | |||
See Page 29-14, Step 10. There are 5 holes in each F-01004C-L/R for double-flush rivets that will need to be machine countersunk from the inboard side of the flange. It will be much easier to do it here rather than waiting until the fuselage is assembled. | |||

Unless otherwise specified by Vans, all rivets should have their machine heads to the inside of the foot well. That is, the machine heads should be on the forward most F-1005B. This will aid the installation of the floor pan on page 35-2. | |||

* Step 3: In section 29, page 29-14, step 9, you will be instructed to machine countersink the outboard #40 holes on the flanges of the F-1005C-L and F-1005C-R Bulkhead Side Channels. If your kit is newer and has final-sized holes, you will not need to final-drill these holes between now and then. Consider countersinking these #40 holes now as it is somewhat easier than doing it after it has been riveted to the fuselage. They should be flush on the outside and should accommodate an AN3 rivet with a 0.032 skin. Section 29-18 shows these five countersunk locations (on the inside of the F-1005C-L and -R parts) to be riveted double flush, just as the seven locations (per side) were done as shown above for Section 25-3. | * Step 3: In section 29, page 29-14, step 9, you will be instructed to machine countersink the outboard #40 holes on the flanges of the F-1005C-L and F-1005C-R Bulkhead Side Channels.
