CAUTION
To prevent possible damage to the main rotor system
assembly fixed length tie-downs must be secured with
approximately 18 inches of slack in the lines.
NOTE
Excellent tie-down points for the fixed length tie-
downs are at the main landing gear trailing arm-
mooring ring and at the wing tip lugs.
(16) Leaving approximately 18 inches of slack, secure fixed-length tie-down to the appropriate area of
airframe.
(17) Repeat steps (1) through (16) above for the opposite rotor blade.
(18) Repeat steps (1) through (17) above for the other set of rotor blades.
g. Rig Shackle Assembly (Figures 1 and 3)
NOTE
During shackle assembly rigging and subsequent recovery
flight all light weight slings and tie-downs attached to the
main rotor blades are to be attached to the clevis part of
the shackle assembly, while the heavy weight black-white
sling is on the shackle assemblies sling spacer.
(1) Remove quick-release pin, clevis pin and sling spacer from the clevis of shackle assembly. (5, Figure
1 and Figure 3)
(2) Place blue/white slings (1) through (4) onto shackle assembly as follows:
(a) Place both sling eyes from blue/white sling at forward airframe transmission support structure
onto the clevis part of the shackle assembly.
(b) Place both sling eyes from blue/white sling at aft airframe transmission support structure onto the
clevis part of the shackle assembly.
(c) Place both sling eyes from blue/white sling at left airframe transmission support structure onto the
clevis part of the shackle assembly.
(3) Place both sling eyes from blue/white sling at right airframe transmission support structure onto the
clevis part of the shackle assembly.
CAUTION
Ensure that the sling spacer is installed when the
shackle assembly is assembled.
(4) Place double eye end of heavy weight black/white sling (6), Figure 1, View A, onto shackle assembly
(Figure 3) and secure shackle assembly as follows:
(a) Insert sling spacer from shackle assembly into the double eye end opening of heavy weight
black/white sling.
(b) Align the holes in the shackle assembly clevis with hole in sling spacer.
(c) Once holes are aligned, insert the clevis pin through the holes in the shackle assembly clevis and
sling spacer.
(5) Insert quick-release pin through hole in base of the clevis pin to secure the clevis pin in the clevis.
