HORIZONTAL STABILIZERS
1.
Clean the entire frame thoroughly.
2.
Add anti-chafe tape (masking tape) around sharp edges of ribs similar to
Flaps, Ailerons and Vertical Stabilizer.
3.
Perform pre-covering check using the following items.
Stabilizer frame is primed.
Ribs installed
Anti-chafe tape applied to sharp edges of ribs
NOTE: Each side of the horizontal stabilizers is covered with a separate piece of
fabric.
4.
Cut fabric large enough to fit the frame and with enough excess to allow
gluing all the way around the frame tubes.
5.
It does not matter which side you apply first.
NOTE: It is recommended to
apply the fabric to the bottom side first. That will make a smoother finish
on the topside.
6.
Glue fabric (first side) all the way around the frame tubes well past the
centerline of the tubes as shown in
FIGURE 08D-06
. Cut the fabric in the
corners, around the stabilizer - attach bushings.
7.
Let dry and iron all fabric edges down.
8.
Pre-iron the fabric surface only enough to take wrinkles out.
9.
Glue fabric (second side) all the way around the frame tubes and past the
centerline as shown in
FIGURE 08D-06.
10.
Let dry and pre-iron the surface only enough to take wrinkles out.
11.
Let dry and final iron entire surface for tightening of fabric.
12.
The fabric will also need to be riveted under Lexan Cover Strips to the
center of each rib. Refer to
WING COVERING - FIGURES 08A-26A
thru
08A-26C
for details about riveting.
13.
The Lexan Cover Straps should extend a minimum of 1/4” past the first
and last rivet. Cut the supplied Straps to length. Apply the small clear
double stick 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 and glue on the Lexan strap. Make sure the
strap is centered over the holes in the ribs.
