TAIL ROTOR CONTROL TUBE (WITHOUT NYLATRON
SLEEVES)
1. Remove and inspect tail rotor control tube for wear at the
five areas where tube contacts tailboom fairleads as follows:
a. To gain access to control tube, remove tail rotor
gearbox fairing and access panel on right side of aft fuselage
adjacent to tailboom.
b. Remove attachment bolts at each end of control tube
through aft end of tailboom and inspect for wear at five areas
where tube contacts fairleads.
c. To determine amount of wear at each location, proceed
as follows:
(1) Measure diameter of tube just forward and aft of
each worn area. Make all measurements in the same plane.
(2) Measure tube diameter in worn area and compare
measurements with those taken in step (1).
(3) If wear does not extend through tube finish,
reinstall tube. If wear in any area extends through dry film
lubricant (black color) and the anodize (brown color), but it is not
in excess of 0.004 inch (0.01 mm) on one side, tube may be
rotated 180° and reinstalled. If wear extends completely around
tube and does not exceed 0.004 inch (0.01 mm) on any side,
reinstall tube assembly end for end.
