(b) Remove access panel LE1, LE2 and RE2. (Refer to 6-00)
(c) Insert rigging lockout pin at rudder actuation pulley in empennage.

(e) Verify rudder neutral position remains at 0±1° with rudder pedals in neutral posi-
tion.

NOTE
•
Typically, the correct rudder deflection (20±1°) is obtained
by measuring 5.8 to 6.2 inches (14.7 to 15.8 cm) between
chord line at upper leading edge of vertical stabilizer and
chord line at lower leading edge of deflected rudder horn.
(See Figure 27-20-3)
(f) Using scale, verify 20±1° rudder deflection angle. If rudder deflection angle falls
outside specified tolerance, perform Adjustment/Test - Rudder System Rigging.
(Refer to 27-20)
(g) On servo capstan, position bridle cable stop-ball at 12 o’clock position (stop-ball
at top of capstan in the capstan recess).
(h) Ensure three wraps of bridle cable exist around capstan and that stop-ball is in
center of cable wrap when cable is at center of travel.
(i) Ensure that stop-ball can not become disengaged from capstan recess or that
bridle cable exit length can not exceed full groove length of capstan.
•
NOTE
•
Use a ratcheting open-end wrench and socket for tight-
ening bridle cable clamp assembly to rudder cable.
Cable clamps may be rotated to ensure proper cable align-
ment on servo capstan.
(j) Position short end of bridle cable and clamp assembly to aft rudder cable and
secure with bolts and nuts. Torque nuts 50±5 in-lb (5.6±0.6 Nm).
(Refer to 20-60)
(k) Route long end of cable forward through pulley assembly.
(l) Position long end of bridle cable and clamp assembly to forward rudder cable
and loosely secure with bolts and nuts.
(m) While pushing long end of bridle cable and clamp assembly forward, tighten
clamp to rudder cable. Torque nuts 50±5 in-lb (5.6±0.6 Nm). (Refer to 20-60)
