•±
An ARPS should be attached
to the aircraft with each
hook Frmly seated on the
cap structure of the WL 119
deck. Its base should rest
Frmly on the work platform
for more support.
•±
An ARPS can be used on
both sides of the aircraft at
the same time.
•±
Because of limited space and
for safety purposes, only one
mechanic should be standing
on each ARPS.
•±
The capacity of the stand is
one mechanic, plus tools and
equipment. However, total
weight should not exceed
400 pounds.

Mechanics, straining to reach
the top of the aft rotor head
while standing on the aft
support platform of your
Chinook is a
real stretch.
You can get
some
relief
with the aft
rotor pylon
step (ARPS).

The aft rotor pylon
step gives you a
step up
so you can
perform maintenance
tasks in a more natural
standing position.
Keep these safety
points in mind when
using the ARPS…
Use the drawings on pages
24-25 to fabricate the ARPS.
The ARPS is
especially
helpful when
you have
to remove,
service or
install the
aft rotor
head.
Without the ARPS, you
don’t
have
a step up. That means you have to
guide the crane and remove all
the components before the rotor
head can be removed.
Problem is, you’ll be doing this
work while reaching overhead in
a position that is uncomfortable
for both tall and short
mechanics, not to mention having
to work in tight spaces.
man, this
step
really
comes in
handy for
working on
the rotor!
I sure
wish
I
haD a
step up with
the ARPS!
