After  marking  the  position  of  the  spar  and  ribs  it  is  a  good  time  to  prepare  the 

cladding areas for gluing. Take a piece of 80 sandpaper and roughen the areas around the 

spar and ribs on the top and bottom liners. A gentle sanding is all that is needed to give 

the resin a good bonding surface. Sand the area within 2 inches of each rib. Sand the area 

2 inches from the front of the back of the spar to the rear edge (hinge line) of the stabilizer. 

4.1.1

 

Horizontal stabilizer spar 

Locate the horizontal stabilizer spar (C123) and remove the

 peel ply

 from the inside. 

Find and mark the center line. Measure 57 inches to the right and left of the centerline 

and trim excess material so that the spar has a total length of 114 inches. Clean and sand 

the top and bottom surfaces for gluing. Align the back side of the spar 1.5 inches from the 

elevator separation line.
