Avenger Missile System…
Dear Editor,
We gave our Avengers some rough workouts in Afghanistan and as a
result found some parts of the Avenger that needed a little more attention
than what the TM prescribes. For instance.
..
The mounting bracket for the ECU/
PPU
air conditioner compressor
If the bracket breaks, the
compressor can fall and rip out
the refrigerant lines. If you're
doing some rough travelling,
daily take off the access panel
for the ECU/PPU and check
the bracket for cracks, espe-
cially the upper right area.
That's where cracks usually
appear. Even if you're not
doing rough driving, it's a good
idea to check the bracket at
least monthly.
Your DOL or aviation shop can usually reinforce the bracket by welding
it. That lets you keep your Avenger on the road until you can get a new
bracket, which comes with PN 13502309.
Azimuth drive motor retaining brackets’ bolts
Rough travel loosens them,
too. If they become too loose,
the bolts' inserts pull out and
either the azimuth drive motor
gear or the main gear for the
pedestal can be damaged.
Check the bolts for looseness
daily if you're driving over lots
of bumps. Tighten them if nec-
essary.
FLIR valve
Make sure Avenger crews
know they are NOT supposed
to push the valve on the FLIR.
That doesn't release air, it
releases nitrogen. The nitrogen
is what keeps moisture out of
the FLIR. Without enough
nitrogen, the life of the FLIR is
cut in half.
FLIR as a watchman
If you're using the FLIR for
perimeter night watches in a
hostile area, don't use the
same system all night, night
after night. That will soon put
that FLIR out of business.
Alternate different Avengers as
much as possible. Remember,
too, that the extreme daytime
heat of the desert can cause
the FLIR to overheat if you run
it for long periods.
Seat
If someone's big foot breaks
the seat, try using a fiberglass
repair kit to fix the area where
the seams split before you
order a new seat. Most home
repair stores have fiberglass
repair kits, as do most DOL
shops. You may be able to save
yourself thousands of dollars,
the cost of a new Avenger
seat.
