Keep Troop Seat Covers Clean
You don't stand on your bird's troop
seats to pull overhead maintenance in
tHe caBin area, do you? Some ±lack
²awk mechs do.
They also use those seats as a handy
resting place fr their tools, lube con-
tainers, oily rags, and all kinds oF odds
and ends. That's why they have to
Replace so many seat cover assemblies
at
$68
a whack. Troop seat abuse can
be an expensiVe proposition.
±ut you're a top ³ight mechanic,
right? You do your job right the ´rst
time, on time, every time. You don't
Lose tools and you don't tear up equip-
ment while you' re Fixing other
equipment.
When you Have to pull overhead
maintenance in the cabin area, you
remove the seats and careµlly place
them where they won't get stepped on
or accumulate dirt, grease, grime, etc.
And when tHosE troop seat covers do
get dir¶ or greasy, you clean 'em like
it says in Para

TM
55-1500-204±25/l.
'Course, when the cover· get ripped
or torn, you send 'em to A¸IM fR
repaiR, like it says in the TM. IF A¸IM
can't repair them, they'll dispose oF
tHem.
The Bottom line
¹
on seat PM is that
you treat those covers like you would
your own household µrniºre.
