are
required
at
each
of
the
inspection
intervals
as
indicated
by
a
(O).
Both
the
annual
and
100-hour
inspections
are
complete
inspections
of
the
airplane,
identical
in
scope,
while
both
the
500
and
1000-hour
inspections
are
extensions
of
the
annual
or
100-hour
inspection,
which
require
a
more
detailed
examination
of
the
airplane,
and
overhaul
or
replace-
ment
of
some
major
components.
Inspections
must
be
accomplished
by
persons
authorized
by
the
FAA.

Piper
service
bulletins
are
of
special
importance
and
Piper
considers
compliance
mandatory.
4.
Piper
Service
Letters
are
product
improvements
and
service
hints
pertaining
to
servicing
the
air-
plane
and
should
be
given
careful
attention.
5.
Inspections
given
for
the
power
plant
are
based
on
the
engine
manufacturer's
operator's
manual
(Lycoming
Part
No.
60297-10)
for
this
airplane,
dated
November
1973.
Any
changes
issued
to
the
engine
manufacturer's
operator's
manual
after
this
date
shall
supersede
or
supplement
the
inspec-
tions
outlined
in
this
report.
6.
Intervals
between
oil
changes
can
be
increased
as
much
as
100%
on
engines
equipped
with
full
flow
(cartridge
type)
oil
filters,
provided
the
element
is
replaced
each
50
hours
of
operation.
7.
Replace
or
overhaul
as
required
or
at
engine
overhaul.
(For
engine
overhaul,
refer
to
latest
Lycoming
Service
Instructions
No.
1009.)
8.
Replace
flexible
oil
lines
as
required
but
no
later
than
1000
hours.
9.
The
compressor
oil
level
should
not
be
checked
unless
a
freon
leak
has
occurred
which
requires
an
addition
of
freon
to
the
system.
10.
Clean
any
traces
of
oil
from
the
clutch
surface.
11.
At
every
400
hours
of
engine
operation,
remove
the
rocker
box
covers
and
check
for
freedom
of
valve
rockers
when
valves
are
closed.
Look
for
evidence
of
abnormal
wear
or
broken
parts
in
the
area
of
the
valve
tips,
valve
keeper,
springs
and
spring
seats.
If
any
indications
are
found,
the
cylinder
and
all
of
its
components
should
be
removed
(including
the
piston
and
connecting
rod
as-
sembly)
and
inspected
for
further
damage.
Replace
any
parts
that
do
not
conform
with
limits
shown
in
the
latest
revision
Lvcoming
Service
Table
of
Limits
No.
SSP1776.
12.
Check
cylinders
for
evidence
of
excessive
heat
indicated
by
burned
paint
on
the
cylinders.
This
condition
is
indicative
of
internal
damage
to
the
cylinder
and
its
cause
must
be
determined
and
corrected
before
the
aircraft
is
returned
to
service.
Heavy
discoloration
and
appearance
of
seepage
at
the
cylinder
head
and
barrel
attachment
area
is
usually
due
to
emission
of
thread
lubricant
used
during
assembly
of
the
barrel
at
the
factory,
or
by
slight
gas
leakage
which
stops
after
the
cylinder
has
been
in
service
for
awhile.
This
con-
dition
is
neither
harmful
nor
detrimental
to
engine
performance
and
operation.
If
it
can
be
proven
that
leakage
exceeds
these
conditions,
the
cylinder
should
be
replaced.
13.
Check
throttle
body
attaching
screws
for
tightness;
the
correct
torque
for
these
screws

50
