INSTALL YAW, THRUST, ROLL OR PITCH ILCA INTERMEDIATE CONNECTING
Make sure bushings are in bellcrank
and link before installing bolts or
component damage will result.
Procedure is same to install yaw,
thrust, or roll pitch ILCA intermediate
connecting links. Thrust link is shown
Impendance bolts are installed in
flight control connections. These
bolts are self-retaining and require a
special nut and torque (Task 1-13).
Remove nut (1), two washers (2 and 3), and bolt
(4) from bellcrank (5).
FLIGHT SAFETY PARTS
This is an installation critical flight
safety part. All aspects of its assembly
and installation must be ensured at
each joint connection.
Ensure bellcrank hub bearings are
serviceable and properly installed.
Ensure lower bearing and sleeve
assembly is properly installed and
Ensure proper attaching hardware
(impedance type bolt, nut, and
washers) is installed including
verification of bolt head orientation,
torque, and installation of cotter pins.
Loose attachments within light control
primary linkage will degrade aircraft
control. Missing components will
cause loss of control.
Position thrust ILCA intermediate connecting link
(6), straight side (7) inboard and lug (8) down, on
bellcrank (5). Install bolt (4), two washers (3 and
2), and nut (1). Do not tighten at this time.
Position straight side of pitch or roll
Remove nut (9), two washers (10 and 11), and
bolt (12) from bellcrank (13).
Position link (6) in bellcrank (13). Install bolt (12),
two washers (11 and 10), and nut (9).
Torque two nuts (1 and 9) to 30 to 45
inch-pounds. Install two cotter pins (14 and 15).
Check two bolts (4 and 12). Bolts shall not rotate
with torque less than 10 inch-pounds. There
shall be no axial looseness. If bolt rotates or is
loose, add washer under nut, and repeat step 5.
Remove servocylinder safety blocks (Task 11-29).
Perform operational check of flight control system
Install closet backup panel (Task 2-2).
Install closet acoustic blanket (Task 2-108).
