10. HOOK-UP AND RECOVERY FLIGHT OPERATIONS (Figure 1 and Table 3)
Should it become necessary for a ground crew
member to perform hook-up while on the helicopter
being recovered, extreme care must be exercised to
avoid static electric shock, injury resulting from falling
off the helicopter as a result of rotor downwash, etc.
Remove any loose objects from recovery site to
prevent them from becoming projectiles as a result of
Figure 1 details the disabled AH-64D helicopter and
recovery helicopter rigging. Reference numbers in the
following text that are outlined in parentheses [i.e., (1), (2),
etc.] refer to Figure 1 and Table 3 item numbers. Refer to
Figure 1 and Table 3 for configuration guidance.
a. Launch recovery helicopter.
b. Direct recovery helicopter into hover position slightly to side of disabled helicopter where sling (11), Figure 1,
View A, has been positioned for connection of the disabled helicopter to the recovery helicopter sling.
Ensure static grounding of recovery helicopter is
accomplished by allowing free end of sling lines to touch
ground before ground crew comes in contact with sling.
Once sling line has come in contact with ground and
after sling line comes in contact with a ground crew
member, the crewmember must maintain continuous
contact with the sling line until it is connected to the
disabled helicopter to maintain static grounding.
c. Allow end of sling line from recovery helicopter to make ground contact to discharge static electricity.
Failure to arrange sling eyes on the sling link assembly
as shown in Figure 1, View E, will create an unbalanced
load on the sling link assembly and may cause the
assembly to open as tension is applied to the slings.
d. Connect single sling eye end of heavy weight black/white sling (11), Figure 1, View A, (connected to disabled
helicopter) to the double eye end of black/white sling (19) (connected to recovery helicopter) using sling link assembly
(1) Verify that arrangement of sling eyes as shown in View E, with sling (11) in the Position B orientation.
