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 safelife limits, which could lead to collapse of the landing gear. ˆ The Agencia Nacional de Aviacao ¸˜ 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 PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 24013 Section of the Maintenance Review Board Report MRB 120–HI–200, which add lifelimited 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 https://www.regulations.gov 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: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • 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: • 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. • 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: E:\FR\FM\25MYR1.SGM 25MYR1 24014 Federal Register / Vol. 82, No. 100 / Thursday, May 25, 2017 / Rules and Regulations ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Maintenance program revision ....................... 1 work-hour × $85 per hour = $85 ................. $0 $85 $5,950 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.

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 https://www.regulations.gov 
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:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2017-10-04 Embraer S.A.: Amendment 39-18878; Docket No. FAA-2016-
9507; Directorate Identifier 2016-NM-127-AD.

(a) Effective Date

    This AD is effective June 29, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Embraer S.A. Model EMB-120, EMB-120ER, EMB-
120FC, EMB-120QC, and EMB-120RT airplanes, certificated in any 
category, all serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
Gear.

(e) Reason

    This AD was prompted by changes to the airworthiness 
limitations, which add life-limited landing gear parts not 
previously identified. 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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Revision of Maintenance or Inspection Program

    Within 90 days after the effective date of this AD, revise the 
maintenance or inspection program, as applicable, by incorporating 
the life-limited landing gear parts and the applicable safe-life 
limits identified in table 1 to paragraph (g) of this AD, as 
specified in EMB-120 Brasilia Maintenance Review Board (MRB) Report, 
Temporary Revision 28-1, dated May 17, 2016.
