TM 1-1670-260-12&P 0009 00 __________________________________________________________________________________________  10.  HOOK-UP AND RECOVERY FLIGHT OPERATIONS (Figure 1 and Table 3)   WARNING 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. CAUTION Remove   any   loose   objects  from  recovery  site  to prevent them from becoming projectiles as a result of rotor downwash.   NOTE 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. WARNING 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. CAUTION 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.   WARNING 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 (20). (1)  Verify that arrangement of sling eyes as shown in View E, with sling (11) in the Position B orientation. 0009 00-13
