D-1 Nozzle strainer check
The D-1 nozzles on all
HEMTT Tanker Aviation
Refueling Systems (HTARS)
and Advanced Aviation
forward Area Refueling
Systems (AAFARS) must
have fuel strainers.
I
f they don’t, a stuck shut-off valve could soak you in fuel or, much worse, cause a
fire. Some D-1 nozzles made by Carter Ground Fueling Co. may not have the strain-
er, which is necessary to prevent fuel debris from lodging in the shut-off valves or
getting into the aircraft.
If your AAFARS uses a Carter nozzle, remove it
and look for the strainer. If the strainer is present
and not torn or obstructed, clean it and reinstall the
nozzle. If the strainer is missing, torn or damaged,
replace it with part number (PN) 47115-100.
Some early versions of the nozzle
fielded with the HTARS contained a uni-
sex coupling that was not machined to
accept the strainer. Later versions were
machined. It is critical that the right cou-
pling is in place to accept the strainer.
If the strainer is torn or damaged,
replace it with PN 47115-100. Dispose
of the bad strainer.
You must order replacement parts
directly from Carter. The telephone
number is (949) 764-2308, fax (949)

I
f your unit’s 7-ton trestles, NSN 4910-
00-251-8013, have a data plate that
shows a manufacturer
other than
Lincoln, or if they do
not
have a data
plate at all, they must be removed from
service and destroyed.
Defective trestles should be destroyed
by crushing, cutting or any other method
that makes them unserviceable and unre-
pairable.
AMCCOM Safety-of-Use Message

TACOM Safety-of-Use Message 00-021 has
the details on the nozzle problem. You can iden-
tify the nozzle by the name “CARTER” cast into
the nozzle’s collar and body.
If your HTARS uses a Carter noz-
zle, remove it and check the strainer.
If it’s present and not torn or
obstructed, clean it and reinstall the
nozzle. If the strainer is missing,
install a new non-valved unisex cou-
pling, PN 64019CN, that will accept
a strainer.
