lace long or thick ribs. Tie off the end of each length with a half hitch as illustrated
in Step 10 and 11 (See Figure 6.4.3), or if needed, separate lengths of lacing
cord may be joined by using the splice knot illustrated in Figure 6.4.4.
(c) Lacing is installed through other components, where applicable, in the same
manner as a wing. Single, wide space lace attachments, usually used on
empennage surfaces, are tied with a square knot and half hitch on each side, the
same as a starting wing rib lace illustrated in Steps 1 and 2 (Figure 6.4.1). The
lace may be rotated to place the knot under the fabric before cutting the cord.
(8) FABRIC RIVETS
Approved blind rivets can be used to secure the fabric to the center and trailing edge ribs
in place of rib stitching. The complete process involves fabric, reinforcement tape, rivets,
and cover tape as shown below.
(1) Rib, (2) Fabric, (3) Reinforcement Tape, (4) Rivet, (5) Cover Tape
Rivet holes should be drilled .125" centered on rib surface. Rivet hole spacing not to
exceed 3.50".
Insert approved rivets (1/8" Polyfibre flush fabric rivets) into holes. Use a pneumatic
riveter set between 90-120 psi to secure rivets. All rivets should be seated flush again
the reinforcement tape. Rivets that are not installed properly should be removed by
drilling through their center with a .125" drill bit or smaller.
