echanics, just because the Kiowa engine deck’s upper and lower oil drain tubes
are out of sight, don’t put them out of mind. You still have to keep them unplugged.
The tubes allow excess oil and condensation to drain off from the transmission
and engine.
If bugs and dirt stop up the
tubes, oil, fluid and condensation
runoff will back up and overflow
the scupper. The liquid overflow
will leak into the AN/ARC-201
radio set’s breather holes and short
it out. Then your communications
are shut down.
To keep the tubes free to drain,
clean ‘em like it says in Para 4-4-
15 of TM 1-1520-248-23. Replace
them if draining doesn’t work.
Oil on
avionics?
Check for clogged
oil drain tubes
[sheesh!]
look at the oil on
the engine deck!
must be a
bunch
of bugs and dirt in
the drain tubes!
that must be
why The
radio’s
not working.
huh?
how d’you
figure
that?
so that’s the
real story of
the lost mission
of zolon
there is a
lesson for
all
of you
out there…
…one’s that as
important today as it
was yesterday and
will be tomorrow.
It’s a
message
that we
should
never
forget
OH-58D…
no matter
how good the
equipment or how
advanced the
technology…
good preven-
tive maintenance
is critical for
uninterrupted
performance!
without PM your
mission is doomed.
You certainly won’t
go where no one
has gone before!
