Dear Editor,
I’ve spent many years working around Kiowa and Huey aircraft. During
that time I’ve seen a lot of corrosion and dirt build up on gearboxes
because the oil filler cap safety chain rubs against the gearbox housing.
Once the bare metal is exposed, moisture accumulates and attracts
dirt and corrosion.
We stopped this problem by
applying a thin film of sealant,
NSN 8030-00-723-2746,
where the chain rubbed. This
eliminated the corrosion
problem—and the complaints
from aircrews who had to clean
up the mess during preflight
inspections.

f your unit refuels aircraft, you must perform daily water (Aqua-Glo) tests and
monthly particulate contaminant (Millipore) tests on the JP-8 aviation fuel you
use. These tests can mean the difference between mission success and disaster.
The millipore test looks for fine sediment that can gum up the engine and lead
to engine failure. The daily Aqua-Glo test looks for water that can freeze at high
altitudes and cause the engine to flame out.
All you need to know is in FM 10-67-1,
Concepts and Equipment of Petro-
leum Operations
(Apr 98). It tells how to set up refueling operations, how to
handle the fuel and lists the NSNs for the test kits.
Chapter 13 has the details on how to qualify personnel to perform the tests. It
also defines the various tests and their purposes.
Appendix E tells you how to do the Aqua-Glo test and Appendix G tells you
how to do the monthly millipore test. The daily millipore test, noted in Appendix
G, is not required except during the initial set-up of a tactical refueling system.
Once the tactical system is operational, the monthly millipore test is all that’s
needed. Unfortunately, the guidance is misleading in the FM, but the next
change to the pub will clarify this point.
If the JP-8 fails any of these tests, a fuel sample must be sent to the nearest
petroleum lab.
Do not use
the fuel until you get the lab report back. The lab will
tell you if the fuel is good to use, must be disposed of or reclaimed. Appendix C
of AR 710-2,
Inventory Management Supply Policy Below the Wholesale Level
(Oct 97), tells you how to process fuel for disposal or reclamation.
For more info on testing JP-8 aviation fuel or to find out the location of the lab
closest to you, call the U.S. Army Petroleum Center, at (717) 770-8580/4392 or
DSN 977-8580/4392. You can e-mail the center at:

It was a dirty job but you cleaned it
up. Good work. The AMCOM experts
say this fix will work on the AH-1
Cobra, too.
