INSTALL YAW MAGNETIC BRAKE
Make sure bushings are in arm before
installing bolt or component damage
Impedance bolts are installed in flight
control connections. These bolts are
self-retaining and require a special
nut and torque (Task 1-13).
If yaw magnetic brake (1) is a replacement,
perform rigging check (Task 11-48).
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 including its
mounting to the pallet assembly.
Ensure mag brake output arm is
properly positioned and secured to
the output shaft of the actuator.
Ensure proper torque values are
utilized when installing brake to pallet
Ensure proper attaching hardware
(self retaining 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.
Position brake (1) on pallet (2) with arm (3)
outboard, receptacle (4) up. Install four bolts
(5) and washers (6). Torque bolts to 45
Position spring (7) and link (8) in arm (3) with link
(8) against lug (9) of arm. Install bolt (10), two
washers (11 and 12), and nut (13).
Torque nut (13) to 30 inch-pounds. If necessary,
continue tightening to align cotter pin holes. Do
not exceed 45 inch-pounds. Install cotter pin
Connect connector (15) to receptacle (4) of brake
(1). Remove tag from connector.
Check bolt (10). Bolt 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 4.
Perform artificial feel forces check (Task 11-34).
Perform operational check of flight controls (TM
Install closet backup panel (Task 2-2).
Install closet acoustic blanket (Task 2-108).
