b. If this white rectangular sticker showing CCAD as the rework activity is not on the servo, the inspec-
tion is complete.
c.
If the rework activity code is "CCAD" and the rework date is after 7/97, the inspection is complete.
d. If the rework activity code is "CCAD" and the rework date is on or before 7/97, then continue with
the inspection and replace IAW paragraph 9.
Correction Procedures.
9.
a. Primary Servo. Physically test all nine Huck Bolts that can be touched without removing the servo.
When the servo is installed on an aircraft, two Huck Bolts on each assembly cannot be touched and must
be visually inspected using a mirror for any obvious damage.
(1) If any collar is missing or is loose (axial or radial play, or can rotate on the pin) with respect
to the swaged pin (Huck Bolt), replace the servo immediately and the action is complete. The collar should
not turn on the swage pin with finger pressure applied.
(2) Visual inspection is not sufficient to determine if the collar is tight,
(3) Turn in any rejected servo assemblies to supply.
(4) If the collars are tight on the swaged pins annotate the DA Form 2408-13-1 to replace the
primary servo within 100 flight hours and the action is complete.
b. Yaw and collective boost and tail rotor servos. Physically test each paragraph 7 fastener (four on
yaw boost assembly, five on collective boost assembly, four on tail rotor servo assembly) for a loost collar,
The collar should not turn on the swage pin with finger pressure applied.
(1) If the collar is missing or has any axial or radial play, then replace the servo immediately and
the action is complete.
(2) If any of the collars on any single assembly is loose (can rotate on the pin) but does not have
any axial or radial play annotate the DA Form 2408-13-1 to replace the servo within the next 100 flight hours
and the action is complete.
(3) If the collars are tight on the swaged pins annotate the DA Form 2408-13-1 for replacement
of the servo no later than the next phase inspection and the action is complete.

curred by the field as a result of SOF actions.
c.

d. Disposition. Dispose of removed parts/components using normal supply procedures. All turn-in
documents will include project code (CC 57-59) "XDU".
