5. DISABLED HELICOPTER RIGGING
6. Inspect Disabled Helicopter for Damage
To prevent death or injury to personnel, and/or
damage to the recovery and/or recovered helicopter,
discontinue the disabled recovery procedure if
damage is detected and refer to Work Package 0012 00
of this manual as directed.
a. Check the main rotor assembly and main rotor support, transmission and transmission mounts, and tail-boom for
damage in accordan ce with applicable technical manual.
b. If damage is determined, discontinue procedure and perform the damaged AH-64A/D recovery procedure
outlined in Work Package 0012 00 of this manual.
c. If no damage is detected in the preceding step proceed to the next step.
7. Install Main Rotor Rigging (Figures 1 and 2, and Table 3)
Figure 1 details the disabled AH-64A 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. Rotate the main rotor assembly to standard tie-down position. (Figure 1, View B)
b. If operable (helicopter with power), to minimize loads on the main and tail rotor blades, set controls to
collective full down, neutral cyclic and pedals.
A short line recovery of an AH-64 helicopter with the
blades on in bad weather or high winds could result
in main rotor blade damage.
