| Drill and cleco the wing tank stops to rib 5 and 7. If you are not installing the extended range fuel tanks then you will install the stops to ribs 5 and 6. Rib 6 is not installed when installing the extended range tanks. NOTE: the stop is installed on the flat side of rib 7 and the inside of rib 6. I don't know why Zenair did not have us mount the rib so that both ribs would have the flat side toward the fuel tank, but this is how the drawing shows them. |
