All
inspections
or
operations
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
of 100
hour
inspections,
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.
3.
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 en-
gine
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
Lycoming
Service
Letter
L201.)
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
seat.
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
for
Lycoming's
Service
Table
of.
Limits
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
is 40 to
50
inch-pounds.
14.

landing
gear
system
in accordance
with
instructions
