Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. 
(Embraer)

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Embraer S.A. Model EMB-120, -120ER, -120FC, -120QC, and -120RT 
airplanes. This proposed AD was prompted by changes to the 
airworthiness limitations, which add life-limited landing gear parts 
not previously identified. This proposed AD would require revising the 
maintenance or inspection program to incorporate new airworthiness 
limitations that add life limits for previously unidentified landing 
gear parts. We are proposing this AD to address the unsafe condition on 
these products.

DATES: We must receive comments on this proposed AD by February 6, 
2017.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

Discussion

    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 proposed AD would require revising the maintenance or 
inspection program 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 http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9507.

Related Service Information Under 1 CFR Part 51

    We reviewed the following Embraer S.A. service information:
     Temporary Revision (TR) 28-1 to MRB Report 120-HI-200, 
dated May 17, 2016. This service information adds life-limited landing 
gear parts not previously identified to the airworthiness limitations 
section.
     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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 70 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

                                       hour = $85.
----------------------------------------------------------------------------------------------------------------

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the

current status is unknown.

 (j) No Alternative Actions and Intervals

    After accomplishing the revision required by paragraph (g) of
