A
ircraft armorer, always handle your AH-64’s target acquisition designation sight
(TADS) with TLC.
That TLC begins by removing the protective
covers from the boresight window, dayside win-
dow and nightside window of the TADS assembly
before you move the turret.
If you leave the covers on, there won’t be
enough clearance between the TADS components
to rotate the turret.
If you force it as you move the
TADS, you could damage the system.
After removing all three window covers and
releasing the azimuth and the elevation brakes,
rotate the turret assembly very slowly, like it says
in Chap 3 of TM 1-1270-476-20. Do it too fast
and you’ll damage the turret.

Dear Sergeant Blade,
Some Black Hawk mechanics get
a little careless and don’t properly
torque the cabin floor screws.
The screws are countersunk
into the floor. You should use only
enough force to seat the screws,
then torque to 20 lb-in. But
when some mechanics tighten
the screws, they force them all
the way through the floor.
We’ve come up with a fix to
help us deal with the problem of
stripped out holes. We install a
larger stainless steel washer under
the existing washer on the screw
to secure the floor. The NSN for
the washer is 5310-00-221-
3106, (P/N A3235-028-24A).

Make sure you fill out DA
Form 2408-13 to annotate this
as a temporary fix so that
the floor will be
properly
fixed at the next scheduled
phase maintenance.

for the cabin floor
is just what the

Dear Sergeant
Brown
(and every-
one else)
, The key
is to limit torque
to 20 lb-in max.
