in
the
servicing
and
maintenance
of
the
air-
craft
and
its
equipment.
Coverage
is
given

The
main
portion
of
the
manual
is
divided
into
nine
parts,
each
of
which
provides
comprehensive
coverage
of
the
systems
and
components
contained
within
the
part.
Each
part
is
provided
with
a
table

the
various
systems
and
com-
ponents
contained
therein.
A
further
breakdown
of
the
text
gives
trouble
shooting,
removal,
installation,
testing,
etc.,
as
applicable
to
the
systems
and
components.
The
need
to
use
more
than
one
part
forrrl.aintenance
of
a
particular
system
has
been
kept
to
a
minimum,
but,
where
necessary,
appropriate
cross-references
are
made.
It
will
be
noted
that
this
manual
does
not
deal
fully
with
items
of

ment.
It
is
suggested,
therefore,
that
every
use
be
made
of
the
(wide

of)
literature
available
from
the
individual
manufacturers;
