FLIGHT SAFETY PARTS
This is an installation critical flight
safety part. All aspects of its assembly
and installation must be ensured.
Ensure that both rod end jam nuts are
installed and torqued.
Ensure that the rivet through the fixed
rod end bearing is secure.
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 flight control
primary linkage will degrade aircraft
control. Missing components will
cause loss of control.
Bushings must be in bellcranks before
installing bolts; otherwise, damage to
components will result.
NOTE
Impedance bolts are installed in flight
control connections. These bolts are
self-retaining and require a special
nut and torque (Task 1-13).
Procedure is same to install forward
left or right connecting links. Left
connecting is shown here.
1.
If left connecting link (1) is a replacement, loosen
nut (2) of adjustable end. Turn bearing (3) 90º to
bearing (4). Torque nut to 103 inch-pounds.
2.
Remove nut (5), two washers (6 and 7), and bolt
(8) from bellcrank (9).
3.
Position link (1) through hole (10) in structure
(11) and in bellcrank (9). Install bolt (8), two
washers (7 and 6), and nut (5) in bellcrank. Do
not torque nut at this time.
4.
Remove nut (12), two washers (13 and 14), and
bolt (15) from bellcrank (16).
5.
Position link (1) in bellcrank (16). Install bolt
(15), two washers (14 and 13), and nut (12) in
bellcrank.
6.
Torque two nuts (5 and 12) to 60 to 90
inch-pounds. Install two cotter pins (17 and 18).
7.
Check two bolts (8 and 15). 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 6.
