7.1.6 Clear the initial entry from para 4.1 and make the following entry on the DA Form 2408-13-1. Enter
a Red Diagonal / status symbol with the following entry: "Reduce wing bolt torque IAW AH-64-03-ASAM-04
during next phase but NLT 1 Feb 04".
7.1.7 Annotate the DA Form 2408-18 with a recurring 30 day inspection (IAW para 7.1) for the wing
mounting bolts until in compliance with either para 7.2 or 7.4. ULLS-A units will use an "800" inspection
number for the recurring 30 day wing bolt torque verification.
7.2 Torque reduction and lubricant application. During the next phase inspection, but NLT than 1 Feb 04,
reduce the torque on the wing mounting bolts and apply lubrication to the bolt threads as follows. This
procedure will be performed on all eight mounting bolts (two upper and two lower on each wing), removing
only one bolt at a time. .
7.2.1 Remove access covers/fairings to gain access to the wing bolts.
7.2.1.1 For the AH-64A, remove access covers (LW9 and RW9) and fairings (LW10, LW11, RW10 and
RW11).
7.2.1.2 For the AH-64D, remove access covers (5LW10, 5LW11, 5RW10 and 5RW11).
7.2.2
Remove wing stores IAW TM 9-1090-208-23-1 or IETM.
7.2.3 Remove upper bolt and washer (TM 1-1520-238-23P, fig 137, items 1 and 2) or lower bolt and washer
(TM 1-1520-238-23P, fig 137, items 3 and 4) (or the IETM) from the wing.
7.2.4
Inspect bolt for damage. No damage allowed.
7.2.5
Lubricate the bolt threads using MIL-T-83483. Ensure lubricant is applied only to the threads.
7.2.6
Install bolt and washer. When installing lower bolts, ensure bolt length is 2.058 to 2.088 inches.
7.2.7
Torque upper bolts to 120 foot-pounds and torque lower bolts to 70 foot-pounds.
7.2.8
Repeat para 7.2.3 to 7.2.7 for all wing mounting bolts.
7.2.9
Reinstall the wing stores IAW TM 9-1090-208-23-1 or IETM.
7.2.10
Reinstall access covers/fairings.
7.2.11 Clear the entry required by paragraph 7.1.6 and make the following entry on the DA Form 2408-13-1.
Enter a Red Diagonal / status symbol with the following entry: "Replace wing mounting hardware IAW
AH-64-03-ASAM-04 NLT 1 Feb 06".
7.2.12 Annotate the DA Form 2408-18 with a recurring 30 day inspection (IAW para 7.3) for the wing
mounting bolts until in compliance with para 7.4. ULLS-A units will use an "800" inspection number for the
recurring 30 day wing bolt torque verification.
7.3 Recurring (every 30 days after torque reduction) wing mounting bolt torque verification. Perform the
following recurring wing mounting bolt torque verification every 30 days until the hardware has been replaced
