echanics, pay attention to detail when installing the rocket launcher on your AH-
64’s wing stubs. It’s a three-person job.
Ensure the jettison plunger on the pylon rack is retracted to the uppermost position.
Make sure the sway brace bolts are fully retracted and remove the ground pin. Lift
the rocket launcher at both ends and position the suspension lugs in the openings
where the suspension hooks are retracted.
When attaching the launcher to the rack, make sure the rack hooks are completely
engaged and seated inside the suspension lugs. Don’t let go of either end of the
launcher until the third person makes sure the hooks lock into place through the
suspension lugs and then inserts the ground safety pin. Once the pin goes in, you’re
safe to let go because the hooks are then secured.
The launcher is heavy. Letting go too soon without the hooks being fully engaged,
can lead to the launcher dropping on your feet or falling to the Foor. A dropped
launcher must be inspected by a technical inspector for serviceability like the
Longbow IETM and TM 9-1055-460-13&P says.
Once the launcher is installed properly, make sure the sway braces are tightened
until they touch the launcher. Using two torque wrenches, simultaneously tighten the
front sway braces

turn and then the rear sway braces

turn. Alternately tighten
the forward and rear braces

turn until the braces are torqued to 100 in-lbs. After
torquing the sway braces, torque each jamnut to 200 in-lbs. Proper torque keeps the
launcher from moving during ±ring. If the launcher is not properly secured, you’ll
have erratic rocket trajectories and missed targets.
As a ±nal step, remember to lower the jettison plunger until it makes contact with
the surface of the launcher. Then back off until the clearance is 0.010 +/- 0.002
inches. You will need to use a feeler gauge for this last step.
