27-30-00 ELEVATOR AND TAB
Refer to Figure 14. The two control sticks (6, 7) are
connected by a push-pull rod (8) inside the torque tube (5).
The control movements are transferred from the rear con-
trol stick (7) to the elevator (2) by push-pull rods (8) and
bellcranks (9, 9a). The bellcranks have two sealed ball
bearings. The elevator is mounted at five points in spherical
bearings pressed into aluminium hinge arms. For lightning
protection reason each hinge arm is grounded to the corre-
sponding attachment bracket at the elevator by bonding
leads. The travel stops (22) are located at the torque tube.
The mass balance weight (21) is mounted on the center
bracket of the elevator extending into the fuselage.
An access panel is located at the right side of the rear
fuselage.
Trim Tab
The elevator trim control lever (16) is located at the right
side in the rear cockpit. Pitch trim is done by means of the
trim tab (14) on the right elevator trailing edge operated by
a bowden cable mechanism (15). The trim tab is mounted
by a piano hinge.
The trim tab is not mass balanced.
