NOTE

All

aircraft,

regardless

of

are

certificated

under

model number

designations.

However,

popular names

are

often

used

for

marketing

purposes.

To

provide

a

consistent

method

of

referring

to

the

various

aircraft,

model

numbers

will

be

used

in

this

publication

unless

names

are

required

to

differentiate

between

versions

of

the

AVIONICS

SERVICE/PARTS

MANUAL

STANDARD

PARTS.

Many

parts

having

standard

usage

have

been

incorpo-

rated

into

the

Cessna

Standard System.

Parts

in

this

group

are

designated

with

the

part

number

prefix

"S."

For

standard

hardware

items

such

as Tinnerman

nuts,

clamps,

etc.,

"AN" and

"NAS"

numbers

have

been

used.

USABLE

ON

CODES.

..

Serial

listings

in

this

catalog

are

noted

by

a

letter

code

located

in

the

usable

on

code

column

which

is

the

extreme

right

hand

column

of

the

parts

list

page.

Usable

on

codes

are

applic-

able

only

to

the

figure

on

which

they

appear.

The

code

letters

and

the

serials

to

which

they apply

are

listed

at

the

end

of

the

figure.

If

no

usable

on

code

appears

opposite

a

first

column

listing

of

the

figure,

the

usage

is

applicable

to

all

models

and

serials

covered

by

this

catalog.

If

no

usable

on

code

appears

opposite

any

indented

list-

ing,

the

usage

is

applicable

to

all

models

and

serials

covered

by

the

figure

on

which

it

appears.

NON-INTERCHANGEABLE

PARTS....

When

parts

are

not

interchangeable

with

earlier

models, all

parts

applicable

to

the

particular

usage

are

listed.

The

letter

code

for

the

individual

part

usage is

listed

in

the

usable

on

column

opposite

each

part.

Care

should

be

exercised

in

determining

proper

serial

when

ordering

to

ensure

receipt

of

correct

part.

INTERCHANGEABLE

PARTS....

When

a

later

design

part

is

completely

interchangeable

with

the

part

it

re-

places,

both

parts

will

be

serialized

and

the

notation

"when

exhausted use

"

will

be

entered

following

the

listing

of

the

earlier

design

part.

This

means

that

the

earlier

design

part

should

be

used

on

air-

planes

to

which they

apply

until

the

supply

of

these

parts

is

exhausted---after

which

time

the

later

de-

sign

part

must

be

used.

This

is

done

to

simplify

stocking

of

parts

by

our

distributors

and

dealers.

The

earlier

part

is as

good,

physically

and

function-

ally,

as

the

later

design

part---the

difference

being

the

later

design

part

can

be

used

on

more

than

one

block

of

airplane

serials.

SYMBOLS

& PART

NUMBER

TERMS.

NP

-

The

AR

-

The

symbol

"AR"

appearing

throughout

the

section.

The

index

numbers

on

the

are

The

purpose

of

the

is

to

pro-

should

not

be-used

column

of

the

shows

the

number

once

at

the

of

the

The

The

remaining

only.

The

column

identifies

the

c.

In

the

column,

relationship

of

covered

is

shown

by

the

degree

of

of

each

item,

for

example:

The

radio

installation

(Figure

is

listed

in

column

(1) of

the

description

column.

The

receiver

is

the

assembly

and

is

therefore

listed

in

column

(2).

d.

If two

or

more

assemblies

contain

a

major-

ity

of

identical

parts

or

the

assemblies

are

left

or

right

hand,

the

assemblies

are

listed

together

and

the

assemblies

or

detail

parts

are

listed

as

common

for

both

assemblies,

with

the

differing

parts

coded

for

usage

on

the

correct

major

assembly.

e.

Attaching

parts are

listed

immediately

be-

neath

the

item

to

be

attached

and

preceding

any

detail

parts

of

the

item.

They

are

listed

in

the

same

column

as

the

item

they

attach

and

are

preceded

by

the

caption "Attaching

The

and

make

sure

the

are

as

Be

sure

to

specify

quantities.

Specify

how

the

order

is

to

be

shipped,

otherwise

it

will

be

sent

out

in

the

manner

that

seems

best

to

the

shipper.

SERIAL,

COLOR,

&

CORROSION

PROOFING.

Be

sure

to

indicate

model

and

serial

number

of

the

airplane.

Serial

number

is

very

important

to

prop-

erly

identify

parts

used

on

each

airplane,

when

color

is

involved.

Be

sure

to

specify

what

color.

If

cor-

rosion

is

desired

add

the

letters

"CP"

fol-

lowing

the

DISTRIBUTION ORDERS.

Distribution

will

send

all

orders

to the

factory

with

instructions

as

to

the

shipping

destination.

The

factory

prefers

not

to make

C.O.D.

shipments

for

the

distributor

and

all

billing will

be

made

to the

distributor

in

the

case

of

direct

shipments.

DEALER

ORDERS.

Dealers

will

place

all

of

their

parts

order

require-

ments

with

their

distributor.

The

factory

will

not

honor

orders

received directly

from

a

dealer.

It

will

be

necessary for

us

to

forward

it

to

the

dis-

tributor

for

his

action.

Therefore,

dealer orders

sent

direct

to

the

distributor

will

result

in

much

faster

delivery

on

any

parts

that

are

required.

RETAIL

ORDERS.

Retail

orders

will

not

be

honored

by

the

factory.

They

are

to

be

placed

with

the

dealer

or

distributor

in

the

owner's

territory

and

when

received

directly

by

the

factory

will

be

forwarded

to

the

distributor

from

whose

territory

it

was

received.

Considerable

saving

in time

will

result

to

the owner

if

his

orders

are

placed

with

his

dealer or

distributor.
