# Authority

for This Rulemaldng Title

49

of the United

States

Code specifies

the FAA's authority

to issue

rules

on aviation

safety. Subtitle

I, section

106, describes

the authority

of the FAA Administrator. "Subtitle

VII: Aviation Programs,"

describes

in more

detail

the scope

of the Agency's authority.

We

are issuing

this rulemaking

under

the authority described

in «Subtitle

VII, Part

A, Subpart

III, Section

44 701: General requirements."

Under

that section, Congress charges

the FAA

with promoting

safe flight

of civil aircraft

in air commerce

by prescribing
regulations

for practices,

methods,

and procedures

the Administrator

finds necessary

for safety

in air commerce.

This regulation

is within

the scope

of that authority because

it addresses

an unsafe condition

that

is likely

to exist

or develop

on products identified

in this rulemaking

action.
