5. Adjustment
After a repair of the trim system a check of the system to verify the correct trim tab deflection given in
Sub-Chapter 06-00 must be carried out. To adjust the system perform the following:
A. Parts in Center Console
Place trim lever in NOSE DOWN position. Pull bowden cable conduit back to the stop. Pull conduit
5 mm (0.2 in.) forward, attach to fitting in center console.
B. Parts in Rudder Fin
The bowden cable must be adjusted to ensure proper tab deflections in accordance with the
Adjustment Report.
The friction damper must be adjusted to a friction force of 15 - 30 N (3.4 - 6.7 lbs.) as follows:
Detail Steps/Work Items Key Items/References
(1) Disconnect RH actuating lever.
(2) Measure friction force with spring scale.
(3) If re-adjustment is necessary, remove fairing at
junction of elevator fin and rudder fin.
(4) Adjust friction. See Figure 1.

The bowden cable position within the mount (clamp block) is fixed by a nut pair on the mount's front
side. This simplifies initial adjustment in the case of repeated removal/installation of the horizontal
stabilizer.
