How

does

FAA process

peti· tions

for rulemaking? 

# After

we have determined

the

disposition

of your petition,

we will

contact

you

in writing

about

our decision. The FAA

may respond

to your petition for rulemaking

in one

of the following ways: (a)

If 

# we determine

that your petition justifies

our taking

the action

you

suggest,

we may

issue

an NPRM

or ANPRM.

We will

do

so

no later

than

6 

# months

after

the date

we receive

your petition.

In making

our decision,

we consider: (1) 

# The immediacy

of the safety

orsecurity concerns

you raise: (Z) 

# The priority

of other
issues

the FAA must

deal with:

and (3) 

# The resources

we have available to address

these issues. (b)

If


# we have issued

an ANPRM

or NPRM

on

the subject

matter

of your petition,

we will consider

your

arguments

for

a rule change

as

a comment in connection

with

the rulemaking

proceeding.

We
will

not treat·

your

petition

as

a separate

action. (c)

If



# we have begun

a rulemaking project

in the subject

area

of your
petition,

we will consider

your comments and arguments

for

a rule change

as part

of that project.

We
will

not treat your petition

as

a separate

action. (d)

If 

# we have tasked

ARAC

to study the general

subject

area

of your

petition,

we will

ask ARAC

to review

and evaluate

your proposed

action.

We will not treat

your petition

as

a separate action. (e)

If


# we determine

that

the issues you identify

in your petition

may have merit,

but

do not address

an Immediate safety concern

or cannot

be addressed because

of other priorities

and resource constraints,

we may dismiss

your

petition.

Your comments

and arguments for

a rule change

will

be placed

in

a database,

which

we will examine

when we consider

future rulemaking.
