7. Tape both sides of the tab break-off line on all

of the tabbed ribs.

9. Locate Rib #2 over the plan and glue it to the

T.E. sheet.

10. Angle-cut the T.E. BACK-UP to fit tight against

Rib 2.

With the back-up flush with the top of the rib,

glue the back-up to the trailing edge sheet.

Cut off the back-up flush with the wing center-

line.

11. Use the Plan to locate the distance between Rib

#3 and and Rib #2.

NOTE: Because the plan paper can stretch some-

what, due to variations in humidity, the plan is not

always an accurate representation of the desired

results. Therefore, to guarantee the ribs are spaced

correctly, a rib spacing gauge is provided. Use this

gauge to measure the distance from the previously

installed rib to the next, making sure that all ribs are

parallel.

12. Use the long side of the rib spacing gauge to

position Rib #4 from Rib #3.
