Discussion ˆ The Agencia Nacional de Aviacao ¸˜ Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directive 2012–01–01, effective January 28, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: This [ANAC] AD results from reports of cracks on the Main Landing Gear (MLG) Side Stay. Further investigation has revealed that the cracks were caused by excessive friction on the MLG Side Stay Support Fitting due to its outer bushing migration. This [ANAC] AD is being issued to prevent such excessive bearing friction which may compromise the MLG free fall extension and; cause fatigue cracks on the MLG Side Stay and on the MLG Side Stay Support Assembly resulting in reduced structural integrity of the MLG. * * * * * The required actions include repetitive measurements of the LH and RH MLG side stay support fitting to detect bushing migration, replacement the bushing if necessary, and eventual replacement of the bushing; a detailed E:\FR\FM\17DEP1.SGM 17DEP1 Federal Register / Vol. 77, No. 242 / Monday, December 17, 2012 / Proposed Rules inspection for damage on the LH and RH MLG side stay support assembly, and related investigative and corrective actions if necessary. The related investigative actions include a general visual inspection and an eddy current inspection for any cracking on the upper and lower side stays of the affected side stay support assembly. The corrective actions include replacing or repairing the MLG side stay or MLG side stay assembly, and removing corrosion. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Embraer S.A. has issued the following service information: • EMBRAER Service Bulletin 190– 32–0043, Revision 02, dated August 23, 2011. • EMBRAER Service Bulletin 190– 57–0036, Revision 02, dated August 12, 2011. • EMBRAER Service Bulletin 190LIN–32–0017, dated June 10, 2011. • EMBRAER Service Bulletin 190LIN–57–0016, dated June 10, 2011. 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 the same type design. Costs of Compliance pmangrum on DSK3VPTVN1PROD with Based on the service information, we estimate that this proposed AD would affect about 97 products of U.S. registry. We also estimate that it would take about 44 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $362,780, or $3,740 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed 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: VerDate Mar<15>2010 15:22 Dec 14, 2012 Jkt 229001 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Airworthiness Directives; Embraer S.A. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Embraer S.A. Model ERJ 190 airplanes. This proposed AD was 
prompted by reports of cracks on the side stay of the main landing gear 
(MLG). This proposed AD would require repetitive measurements of the 
left-hand (LH) and right-hand (RH) MLG side stay support fitting to 
detect bushing migration, replacement of the bushing if necessary, and 
eventual replacement of the bushing; a detailed inspection for damage 
on the LH and RH MLG side stay support assembly, and related 
investigative and corrective actions if necessary. We are proposing 
this AD to prevent excessive bearing friction, which might compromise 
the MLG free fall extension, and cause fatigue cracking on the MLG side 
stay and on its support assembly, resulting in reduced structural 
integrity of the MLG.

DATES: We must receive comments on this proposed AD by January 31, 
2013.

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 2012-01-01, effective January 28, 2012 
(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    This [ANAC] AD results from reports of cracks on the Main 
Landing Gear (MLG) Side Stay. Further investigation has revealed 
that the cracks were caused by excessive friction on the MLG Side 
Stay Support Fitting due to its outer bushing migration. This [ANAC] 
AD is being issued to prevent such excessive bearing friction which 
may compromise the MLG free fall extension and; cause fatigue cracks 
on the MLG Side Stay and on the MLG Side Stay Support Assembly 
resulting in reduced structural integrity of the MLG.
* * * * *
The required actions include repetitive measurements of the LH and RH 
MLG side stay support fitting to detect bushing migration, replacement 
the bushing if necessary, and eventual replacement of the bushing; a

inspection for damage on the LH and RH MLG side stay support assembly, 
and related investigative and corrective actions if necessary. The 
related investigative actions include a general visual inspection and 
an eddy current inspection for any cracking on the upper and lower side 
stays of the affected side stay support assembly. The corrective 
actions include replacing or repairing the MLG side stay or MLG side 
stay assembly, and removing corrosion. You may obtain further 
information by examining the MCAI in the AD docket.

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 the same 
type design.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 97 products of U.S. registry. We also estimate that 
it would take about 44 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $362,780, or $3,740 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
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 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

    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]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Embraer S.A.: Docket No. FAA-2012-1227; Directorate Identifier 2012-
NM-016-AD.

(a) Comments Due Date

    We must receive comments by January 31, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Embraer S.A. Model ERJ 190-100 STD, -100 LR, 
-100 ECJ, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 
LR, and -200 IGW airplanes; certificated in any category; as 
identified in the service information specified in paragraphs (c)(1) 
and (c)(2) of this AD.

(d) Subject

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

(e) Reason

    This AD was prompted by reports of cracks on the side stay of 
the main landing gear (MLG). We are issuing this AD to prevent 
excessive bearing friction, which might compromise the MLG free fall 
extension, and cause fatigue cracking on the MLG side stay and on 
its support assembly, resulting in reduced structural integrity of 
the MLG.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Measurement for Bushing Migration of the MLG Side Stay Support 
Fitting

    Within 100 flight cycles after the effective date of this AD: 
Measure the left-hand (LH) and right-hand (RH) MLG side stay support 
fitting to detect bushing migration, in accordance with Part I of 
the Accomplishment Instructions of EMBRAER Service Bulletin 190-57-
0036, Revision 02, dated August 12, 2011 (for Model ERJ 190-100 STD, 
-100 LR, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, 
and -200 IGW airplanes); or EMBRAER Service Bulletin 190LIN-57-0016, 
dated June 10, 2011 (Model ERJ 190-100 ECJ airplanes).
    (1) If the distance of bushing migration is less than 5 
millimeters (mm), repeat the measurement required by paragraph (g)
