Dear Rotor,
Flying in sandy desert conditions clogs the Kiowa’s barrier filters
faster than you can say “Hooah.”
So, we service, change, clean or shake out the primary filters more
than usual to keep clean air going into the engine.
But because the clogging is so much of a problem, we also remove the
blast
shield
(part of the
engine cowling)
to expose part
of the primary
filter.
This
allows some of
the sand and
dust to blow by
and not collect
and clog the
filter so fast.
It sure helps
keep us flying.

Dear SGT Batrony,
Good work! Great idea to remove the cowling to extend the usefulness of the pri-
mary filters.
Here are some other ideas to help you keep the filters clean:
•
Do your full service
cleaning of the EBF system
like it says in Para 4-2-14 of
TM 1-1520-248-23 IETM
and the commercial manu-
al. To shake out sand and
dirt from the primary filter,
use
the
shaker
tool
described in the EBF filter
system manual.
•
Keep a cover on the bleed air filter to protect it when your bird is not flying.
•
NSN 6850-01-514-3592 brings
the 5-gal filter cleaning solvent.
NSN 9150-01-514-3640 brings
the 5-gal filter oil.
•
Contact Tamara Sission of AFS
at (636) 498-6003 ext. 218 and
use quotation #200221 (29 Jan
03) to get your deployment kit
containing pliers to straighten out
filter pleats.

Clean filter like IETM and commercial manual says
Order air filter oil and cleaner by NSN
After full service
cleaning, oil
primary filter
like IETM says
When the bird is
not
in use, cover
the bleed air filter
for protection

My EBF filters
are clogging
too fast
in
this desert!
some of the
sand can blow
past the filter.
don’t worry, taking
off your blast shield
will do the trick.
