14. Blade Pole Assembly (View M)
The blade pole assembly is used to lift the blade sleeve assembly up to the blade of a disabled/damaged
helicopter. The blade pole assembly is composed of four aluminum sections, a yoke, tail hook, and upper and
lower handle sections. The attachment points of each section are color coded and secured with quick-disconnect
pins. Assembly of the blade pole assembly is as follows:
a. Insert the tail hook into the yoke, aligning the red stripes and quick-disconnect pinhole. Insert the quick-
disconnect pin B.
b. Insert the upper handle into the yoke, aligning the yellow stripes and quick-disconnect pinhole. Insert quick-
release pin A.
c. Insert the lower handle into to upper handle, aligning the black stripes and quick-disconnect pinhole. Insert
quick-release pin C.
15. UH-1 Square Wedges (Sheet 4,View N)
The UH-1 square wedges are installed on the main rotor stops to prevent tilting of the main rotor during
transportation of the disabled helicopter. The wedges are constructed of synthetic rubber. One wedge is equipped
with a wire rope with a spring steel snap ring attached. The second wedge is equipped with a wire rope only. The
snap ring and wire rope are used to position and secure the square wedges.
16. AH-1 and OH-58A/C Mast Wedges (View O)
The AH-1 and OH-58 A/C mast wedges are circular silicone rubber tubes that are used to position and secure the
disabled helicopter mast during transportation. Two sizes are included in UMARK. The large diameter mast wedge
is used to secure the AH-1 mast and the small diameter mast wedge is used to secure the OH-58 A/C masts.
Each mast wedge is equipped with a wire rope on one side and a spring steel snap ring attached with wire rope on
the opposite side. The wire rope is passed over the top of the main rotor and attached to the snap ring on the
opposite side. This secures the mast wedge to the mast and main rotor and prevents tilting of the main rotor
17. OH-58D Sight Wedge (View P)
The OH-58D sight wedge is used to stabilize the mast-mounted sight during transportation of the disabled
helicopter and to stabilize the sight during assembly of the crossbar. The sight wedge is constructed of neoprene
rubber. It is equipped with a lanyard and snap that is used to secure the sight wedge into position.
18. Box Link Assembly (Sheet 5, View Q)
A box link assembly is used to connect two slings in series configuration. Components of a box link assembly
include the box link housing, two box link pins, and two quick release pins. Two holes, corresponding to the
diameter of the box link pins, are drilled on the top and bottom of the box link housing. The two box link pins and
the two quick release pins are interconnected by wire rope.
19. Sling Link Assembly (Views R and S)
A sling link assembly is used to connect slings. Components of the sling link assembly include a sling link pin with
attached spring lock. Failure to arrange sling eyes on the sling link assembly as shown in Figure 1, Sheet 5, View
S will create an unbalanced load on the sling link assembly and may cause the assembly to open as tension is
applied to the slings. View R shows a safety wired joint that keeps the attached end of the sling link lock from
separating from the sling link pin. Each recovery Work Package in the manual provides detailed instructions for
the proper and safe use of the sling link assembly. These instructions shall be adhered to.
