SERVICE
The spinner and backing
plate
should
be cleaned
and inspected
for
cracks frequently.

propeller
should
be
inspected
for nicks, scratches,
and
corrosion.
If
found,
they
should be repaired
as soon
as
possible
by a
rated
mechanic,
since
a
nick or
scratch
causes
an
area
of
increased stress which
can
lead
to serious
cracks
or
the
loss
of a
propeller
tip.
The back face
of
the
blades
should
be
painted
when necessary
with
flat
black
paint
to
retard
glare.

prevent
corosion, the
zurface
should
be
cleaned
and
waxed
periodically.
