22. Let dry. Iron the fabric along all the frame tubes and iron all the fabric
edges down.
23. Pre-iron the fabric all the way around to remove wrinkles and to
pre-tension the fabric.
24. Size the fabric around the horizontal stabilizer bushings using thinned
glue. Let dry and cut to allow the fabric to slip over the bushings.
25. Final tension the bottom and both sides evenly. Use care when applying
heat to the flat lap-joint area, as heat will soften the adhesive and the bond
will separate.
26. The fabric will also need to be riveted under a reinforcement Lexan Cover
Strap to the center of the vertical stabilizer rib. Refer to
WING COVERING
FIGURES 07A-26A to 07A-26C for details about riveting.
27. The Lexan Cover Straps should extend a minimum of 1/4” past the first
and last rivet. Cut the supplied Lexan Cover Straps to length. Apply the
small clear double-stick (2-way) tape on top of the fabric centered along
each rib and extending 1/4” past the first and last hole. Remove the
protective paper on top of the double-stick tape apply the Lexan strap.
Make sure the strap is centered over the holes in the ribs.
28. Use a hot knife with a pointed tip or a soldering iron and melt through the
cover strap and the fabric into the rib holes.
29. Cut the melted build up, on top of the Lexan straps, off using a razor
blade.
30. Insert a rivet in each hole and rivet.
31. Bond all exit rings, inspection rings and the rudder cable exits in place as
follows.
32. NOTE: A template is used to locate the elevator yoke exit rings (both
sides of fuselage) and Rudder Cable Exit Fairings.
Fabricate template by
cutting out and gluing together the 4 parts using FIGURE 07C-32 thru
07C-32C . Mark the ring location, scuff surface of rings and glue to fabric.
33. Cut out the Rudder Cable Exit Fairings from supplied sheet and cut out
opening for Rudder Cable in aft end of fairings.
34. Mark location as per template, scuff surface of fairing and glue direct to
fabric (both sides of fuselage).
35. Mark locations, scuff surface and glue on inspection rings, drain
grommets, access ring and the 2” ring at the fuel drain location. Reference
FIGURES 07C-34 , 07C-35, and 07C-35A for guidance.
