Make sure bushings are in bellcrank
and support before installing bolts or
component damage 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).
1.
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.
After electrical nulling procedure is
accomplished, ensure adjustable rod
end bearing assembly is properly
saftied by torquing jam nut against
locking tab washer assembly per
BAC5009, and installing safety wire
between jam nut and locking tab
washer assy per BAC5018.
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
secondary linkage will degrade
aircraft control. Missing components
will cause loss of control.
2.
Position pitch linear transducer (6) adjustable
end (7) up, on outboard side of bellcrank (5).
Install bolt (4), two washers (3 and 2) and nut (1).
Do not tighten nut at this time.
3.
Remove nut (8) and washer (9) from bolt (10).
Slide bolt outboard until flush with support (11).
4.
Position transducer (6), wires (12) forward, on
support (11). Install bolt (10) washer (9), and
nut (8).
5.
Torque two nuts (1 and 8) to 30 to 45
inch-pounds. Install cotter pins (12 and 13).
6.
Check bolts (4 and 11). 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.
Connectors must be installed in fully
locked position; otherwise, component
malfunction can result.
7.
Connect connector (14) of wire with green band
of transducer (6) outboard receptacle (15) on
structure (16). Remove tag.
8.
Connect connector (17) of wire with red band
of transducer (6) to inboard receptacle (18) on
structure (16). Remove tag.
NOTE
When connecting CPT to structure
receptacle, check to ensure wiring is
connected to the correct marked and
banded wire both ends.
