MANUAL
TIRES
The
main
wheel
tires
are
6-ply
or
8-ply
6.50
X
8 tires and
the
nose
wheel tire
is
a
6-ply
5.00
X
5
tire.
Maintaining
proper
tire
inflation
will minimize
tread
wear
and
in
preventing
tire
rupture
caused
from
running
over
sharp
stones
and
ruts.
When
inflating
tires,
visually
inspect
them
for
cracks
and
breaks. For
correct
inflation
see
General
Information
in
Section
1.
In
service,
tire
carcasses
grow
slightly
due
to
shock
loads in
landing.
Normally,
this
growth
is
balanced
by
tread
wear
I
so
there
is
no
increase
in
tire
diameter.
Raytheon
Aircraft
Company
cannot
recommend
the
use
of
recapped
tires.
The tires
may
pass
the
retraction
test
when
first
installed; however,
recapped
tires have
a
tendency
to
swell
after
use
and
may
cause
malfunction
of
the
retract
system
or
damage
the
landing
gear
doors.
CAUTION:
Because
of
possible
damage
to the
retract
system
or
landing
gear
doors,
tires that
measure more
than
62.33
inches
in
circumference
or
19.85
inches
in
diameter should
not
be used.
Oil and other
hydrocarbons
spilled
on
the
tires
not
only
weaken the rubber
but
may
cause
them
to
swell. Avoid
spilling
oil,
fuel
or
solvent
on
the
tires and clean off
any
accidental
spillage
as
soon as
possible.
I
NOTE:
While
Raytheon
Aircraft
Company
cannot
recommend the
use
of
recapped
tires,
tires retreaded
by
an
FAA
approved
repair
station
with
a
specialized
service
limited
rating
for
TSO-C62d
may
be
used.
BRAKES
The fluid
reservoir,
accessible
through
the
forward
baggage
compartment,
should
be checked
regularly
and
a
visible
I
fluid
level
maintained
on
the
dipstick
at
all times
by adding hydraulic
fluid
(13,
Chart
3).
LANDING
GEAR
The
landing
gear
retract
mechanism
is
a
complex
system
with
very
small
clearances
between
working
parts.
Adjustments
should
be
made
only
at
a
Raytheon
Aircraft
Company
Authorized
Service Station.
Any
malfunction
should
be
corrected
by
an
Authorized
Service
Station.
LANDING
GEAR
AND
TIRES
Emulsion
type
cleaners
are
recommended
for
cleaning landing
gear.
These
solutions
usually
contain solvents
which
are
injurious
to
rubber
if
allowed
to
remain
in
contact
for
any
length
of time.
If
these solvents
come
in
contact
with
tires
as
a
result of
other
cleaning
operations,
the
solvent
should
be removed
with
a
thorough
water
rinse.
WHEEL
WELL AND
NACELLES
Most
compounds
used for
removing
oil,
grease,
and
surface
dirt from wheel
wells
and nacelles
are
emulsifying
agents.
These
compounds,
when mixed
with
petroleum
solvents,
emulsify
the
oil,
grease,
and dirt. The emulsion is
then
removed
by
rinsing
with
water
or
by
spraying
with
a
petroleum
solvent.
Take
the
following
precautionary
measures
while
cleaning
the wheels and
nacelles:
a.
Coveropeningsand
airscoops.
b.
During
cold
weather
(if
water
rinse
is
used)
remove
any
evidence
of
water
by
blowing
out
with
an
air
gun.
Any
water
that
remains
may
freeze and
lock
the
controls.
