echanics, the battery in your AH-64D will work as long as you don’t leave aircraft
power switches on, draining the battery.
For example, when your aircraft needs refueling, the fuel handlers get in a hurry
and sometimes forget to shut off the refuel control panel after the job is done. Leaving
the fuel switch in the ON position drains power from the battery.
If the battery, NSN 6140-01-425-7235, gets drained, you’ll need to remove it from
the bird and recharge it like it says in TM 1-1520-Longbow/Apache, EM 0126.

we told you what maintenance you could and could not
perform on the microclimate cooling unit system.
Now we need to tell you the two acceptable ways to wear the microclimate cooling
garment (MCG). To get the maximum cooling from your vest, always wear it either over a
T-shirt or directly against the skin. Those are the two right ways.
Never
put the vest on over the flight suit or jacket. This might puncture the MCG and you
won’t stay cool when the heat beats down on you.
Recharging the battery takes about
an hour. You can use your battery
charger, NSN 6130-01-465-2674, to
put the juice back into the battery.
Your bird will be on the NMC list
until this is ±nished.
If you have any questions or problems with your MCG, log on to the Air Warrior web site:
If you don’t have an account, you’ll
need to request one. Approval usually
takes 24 hours. Once logged in, click on
the Ask Air Warrior link to type in your
questions. Order a vest from this list:
