limitations, which add life-limited landing gear parts not previously
identified. This AD requires revising the maintenance or inspection
program, as applicable, to incorporate new airworthiness limitations
that add life limits for previously unidentified landing gear parts. We
are issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to all Embraer S.A. Model EMB-
120, -120ER, -120FC, -120QC, and -120RT airplanes. The NPRM published
in the Federal Register on December 21, 2016 (81 FR 93647). The NPRM
was prompted by changes to the airworthiness limitations, which add
life-limited landing gear parts not previously identified. The NPRM
proposed to require revising the maintenance or inspection program, as
applicable, to incorporate new airworthiness limitations that add life
limits for previously unidentified landing gear parts. We are issuing
this AD to prevent life-limited landing gear parts from being used
beyond their safe-life limits, which could lead to collapse of the
landing gear.
The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC),
which is the aviation authority for Brazil, has issued Brazilian
Airworthiness Directive 2016-07-02, dated July 27, 2016 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all Embraer S.A.
Model EMB-120, -120ER, -120FC, -120QC, and -120RT airplanes. The MCAI
states:
This [Brazilian] AD was prompted by changes to the Airworthiness
Limitation Section of the Maintenance Review Board Report MRB 120-
HI-200, which add life-limited landing gear parts not previously
identified. We are issuing this [Brazilian] AD to prevent life-
limited landing gear parts from being used beyond their safe-life
limits, which could lead to collapse of the landing gear.
This AD requires revising the maintenance or inspection program, as
applicable, to incorporate new airworthiness limitations that add life
limits for previously unidentified landing gear parts. You may examine
the MCAI in the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a>
by searching for and locating Docket No. FAA-2016-9507.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting this AD as proposed except for
minor editorial changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
We reviewed the following Embraer service information:
<bullet> EMB-120 Brasilia Maintenance Review Board (MRB) Report,
Temporary Revision 28-1, dated May 17, 2016. This service information
adds life-limited landing gear parts not previously identified to the
airworthiness limitations section.
<bullet> Alert Service Bulletin 120-32-A543, dated July 11, 2016.
This service information provides procedures for replacement of
affected parts.
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.
Costs of Compliance
We estimate that this AD affects 70 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

Authority for This Rulemaking
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 44701: 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.
Regulatory Findings
We determined that this AD will not have federalism implications
under Executive Order 13132. This AD will not have a substantial direct
effect on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in Alaska; and
4. Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
