AIRFRAME

MAINTENANCE

AIRFRAME SEALING

The

airframe

is

sealed

during

manufacture

of

the

various

subassemblies

and

again

after

airframe

com-

pletion. The follOWing

information

is

included

to

assist

in the

maintenance

and

repair

of

the

airframe

to obtain a

correct

and

lasting

seal

when

replacing

any

structural

parts.

SEALANT

AND

INSULATION MATERIALS.

The

following

is

a

list

of

sealants

and

materials

to

be

used

in

the

Dash

numbers

Example:

A-2

indicates

a

brush-

able

material

having a

2-hour

maximum

work

life.

Prior

to

use,

all

sealants

are

to

be

stored

in a

refrig-

erator.

Two-

part

sealants

should

be

mixed

only in

the

quantity

required

for

a

specific

task.

Surplus

ad-

hesive

should

be

discarded

since

the

storage

life

of

mixed

sealants,

even

under

refrigeration,

is

very

limited.

The

two-part

sealants

have

a

definite

and

limited

work

life

after

being

mixed;

the

work

life

being

the

length

of

time

the

sealant

will

remain

in

a

workable

form

before

becoming

too

hard.

Before

mixing

the

sealant,

the

amount

needed

for

the

specific

job

should

be

estimated

and

only

that

amount

mixed.

Do

not

try

to

seal

an

area

so

large

that

the

job

cannot

be

finished

within

the

work

life, of

sealants.

By

using

these

simple

precautions

a

great

deal

of

time

and

sealant

may

be

saved.

CLEANING MATERIALS

AND

TOOLS.

SEALING PROCEDURES.

The

following

procedures

are

provided

to

enable

operators

to

obtain

successful

sealing

of

the

airframe

during

and

following

repairs.

Cleaning

Remove

grease,

oil,

dirt,

chips

and

all

foreign

ma-

terial

prior

to

cleaning.

The

success

of a good

seal

depends

on

the

thorough

cleaning

of

both

surfaces

of

the

affected

parts

to

be

sealed.

Cleaning

can

be

ac-

complished

using

expendable

gauze

sponges

or

a

clean

lint-free

cloth.

Scrub

both

surfaces

until

cloth

re-

mains

clean

after

wiping. Do not

use

an

excessive

amount

of

solvent.

For

the

final

cleaning,

wipe

sur-

faces

dry

with a

clean

dry

cloth

to

remove

any

film

left

by

the

evaporation

of

the

solvent.

The

area

cleaned

should

be

slightly

wider

than

the

width of

the

sealant

to

be

applied.

All

cleaning

solvent

should

be

removed

from

assembly

faying

surfaces

with

oil-free,

com-

pressed

air.

If any

primer

or

paint

is

removed
