echanics, always pay attention where your feet, rear and hands go when working
on your AH-64.
For example, the APU cover provides just a little protection for the auxiliary power
unit (APU). But as tempting as it may be, the cover is not a chair, a work stand or a
step. It’s just a cover for protecting the APU.
Standing, sitting or stepping on the
cover will break it. The cover can’t
handle your weight. Worse, a cracked
APU cover can rub against an APU
fuel line over time and cause a fuel
leak. That’s not good!
So, when you’re walking on the
catwalk area and working around the
APU cover, think of the cover as part
of the APU, not part of your bird’s
airframe. And stay off it!

ot taking precautions to protect your AH-64A/D from water during washing is no
laughing matter.
During your next aircraft washing, make sure the No. 1 and 2 generators are
bagged and tied ±rst.
Water directed at unprotected generators will cause them to fry during aircraft
startup and give a mechanic some unnecessary maintenance grief.
A dry generator after washing means your bird will be up and running. A wet
generator means your bird will be NMC.
And while washing your bird, make it a habit to cover the pitot tubes so water
doesn’t enter them either. Water in pitot tubes means the pilot and co-pilot can’t tell
their airspeed and windspeed.
