3. CONSTRUCTION PROCEDURES. Bonding Horizontal Stabilizer Horizontal Tail lignment Fig. 11::1 Trimming Left Vertical Skin Trim remainder fit tail. This is a gradual trim and fit process using tail. The ideal gap between and should be between 0.05 and 1/8. Upper Upper bulkhead, bulkhead, 4049 4049 Lower Lower support support Horizontal stabilizer In chapter 7, we mentioned that cradles are final aligned in this chapter. To explain what end goal is, consider following requirements: 1. The tail incidence is -0.6 O -0.3 O. lso refer chapter 7. 2. The tail must be centered. 3. The stabilizer must fit lower support. Visually check this. Bed on se three criteria, adjust cradles necessary. Recheck all alignments! Trim Trim skin skin lower lower support. support.

Horizontal Stabilizer Center Line To properly center stabilizer, you need an accurate center line. We suggest that you use center hinge and transfer a center line on upper skin. lign tail plumb bob. Horizontal stabilizer Proper Horizontal Stabilizer Installation during Bonding To avoid scraping adhesive off during bonding, it is important install stabilizer at an angle. Note that right cradle is removed during step. 1 Slide at an angle. 2. Lower in place and align. PRCTICE BEFORE BONDING!!! The right cradle is temporarily removed during stabilizer installation.
