GENERAL.
The
instrumentation
in
the
Lance

is
designed
to

a
quick
and
actual
indication
of
the
attitude,
performance
and
condition
of
the
airplane.
Maintenance,
other
than
described
in
these
sections
shall
be
done
by
the
instrument
manufacturer
or
an
authorized
repair
station.

The
first
part
of
this
section
will

and
their
systems
which
depend
on
non-electrical

SERVICE
TIPS.
The
following
information
is
intended
to
acquaint
field
service
personnel
with
a
means
to
diagnose
vacuum
system
service
symptoms
on
those
components
which
are
serviced
by
removal
and
replacement.
These
itmes
include
hoses,
clamps,
vacuum
system
filters,
vacuum
regulating
valve
and
suction
gauge.
a.
Hoses
and
Clamps:
1.
These
items
should
be
examined
periodically
and
inspected
carefully
whenever
engine
maintenance
activities
cause
hose
disconnections
to
be
made
at
the
pump,
regulating
valve,
gyros
and/or
vacuum
gauge.
2.
The
ends
of
the
hoses
should
be
examined
for
rubber
separation
and
slivers
of
rubber
on
the
inside
diameter
of
the
hoses.
These
slivers
can
and
do
become
detached.
If
this
happens,
the
vacuum
pump
suck
these
loose
particles
and
eventually
ingest
them.
This
can
cause
premature
pump
service.
3.
Hose
clamps
and
fittings
should
be
replaced
when
broken,
damaged
or
corroded.
CAUTION
When
replacing
any
of
the
threaded
fittings,
DO
NOT
USE
PIPE
DOPE
or
any
other
anti-seize
tape
or
compound.
The
AIRBORNE
fittings
are
all
cadmium
plated
to
avoid
the
need
for
any
other
anti-seize
materials.
The
reason
for
this
caution
is
to
protect
the
pump
from
ingesting
any
foreign
materials
that
could
cause
premature
service.
