[FR Doc. 2012–13671 Filed 6–5–12; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2012–0590; Directorate Identifier 2011–NM–112–AD] RIN 2120–AA64 Airworthiness Directives; Embraer S.A. Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to all Model ERJ 190–100 SUMMARY: E:\FR\FM\06JNP1.SGM 06JNP1 mstockstill on DSK4VPTVN1PROD with PROPOSALS Federal Register / Vol. 77, No. 109 / Wednesday, June 6, 2012 / Proposed Rules STD, –100 LR, and –100 IGW airplanes; and Model ERJ 190–200 STD, –200 LR, and –200 IGW airplanes. The existing AD currently requires revising the maintenance program to incorporate modifications in the Airworthiness Limitation Section (ALS) of the Embraer S.A. ERJ 190 Maintenance Review Board Report (MRBR). Since we issued that AD, new inspection tasks and their respective thresholds and intervals have been issued. This proposed AD would require revising the maintenance program to incorporate modifications in the Airworthiness Limitation Section (ALS) of the Embraer S.A. ERJ 190 Maintenance Review Board Report (MRBR) to include new inspection tasks and their respective thresholds and intervals. We are proposing this AD since failure to inspect these structural components according to the new ALS tasks, thresholds, and intervals could prevent a timely detection of fatigue cracking, which if not properly addressed, could result in reduced structural integrity of the airplane. DATES: We must receive comments on this proposed AD by July 23, 2012. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov. Follow the instructions for submitting comments. • Fax: (202) 493–2251. • Mail: U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC 20590. • Hand Delivery: U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

SUPPLEMENTARY INFORMATION: tasks and its respective thresholds and intervals. Failure to inspect these structural components, according to the new tasks, thresholds and intervals, could prevent a timely detection of fatigue cracking. These cracks, if not properly addressed, could adversely affect the structural integrity of the airplane. Since this condition may occur in other airplanes of the same type and affects flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance with this [ANAC] AD in the indicated time limit. Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2012–0590; Directorate Identifier 2011–NM–112–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD based on those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Relevant Service Information Embraer S.A. has issued Part 2— Airworthiness Limitation Inspections (ALI)—Structures, of Appendix A, Airworthiness Limitations (AL), of the EMBRAER 190 Maintenance Review Board Report, MRB–1928, Revision 5, dated November 11, 2010; and Temporary Revision (TR) 5–1, dated February 11, 2011, to Part 2— Airworthiness Limitation Inspections (ALI)—Structures, of Appendix A, Airworthiness Limitations (AL), of the EMBRAER 190 Maintenance Review Board Report, MRB–1928, Revision 5, dated November 11, 2010. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. Discussion On May 13, 2010, we issued AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010). That AD required actions intended to address an unsafe condition on the products listed above. Since we issued AD 2010–11–14, Amendment 39–16319 (75 FR 30277, ˆ June 1, 2010), the Agencia Nacional de Aviacao Civil (ANAC), which is the ¸˜ airworthiness authority for Brazil, has issued Brazilian Airworthiness Directives 2010–08–03, dated September 20, 2010, and 2011–05–04, dated June 16, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: During the airplane full scale fatigue test, cracks were found in some structural components of the airplane. Analysis of these cracks resulted in modifications on the Airworthiness Limitation Section (ALS) of Embraer ERJ 190 Maintenance Review Board Report (MRBR), to include new inspections PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 The required action is revising the maintenance program to incorporate new structural inspection requirements. 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. Correction To Restate Table 1 of AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010) Table 1 of AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010), contains a reference to EMBRAER Temporary Revision (TR) 2– 6, dated December 12, 2008, to Part 2— Airworthiness Limitation Inspections (ALI)—Structures, of Appendix A, Airworthiness Limitations (AL), of the EMBRAER 190 Maintenance Review E:\FR\FM\06JNP1.SGM 06JNP1 33336 Federal Register / Vol. 77, No. 109 / Wednesday, June 6, 2012 / Proposed Rules Board Report, MRB–1928. We have determined that the correct date for that TR should be February 12, 2008. That information is reflected in table 1 of this proposed AD. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 88 products of U.S. registry. The actions that are required by AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010), and retained in this proposed AD take about 1 workhour per product, at an average labor rate of $85 per work hour. Based on these figures, the estimated cost of the currently required actions is $85 per product. We estimate that it would take about 1 work-hour per product to comply with the new 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 $7,480, or $85 per product. 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. mstockstill on DSK4VPTVN1PROD with PROPOSALS 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; VerDate Mar<15>2010 16:11 Jun 05, 2012 Jkt 226001 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. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing airworthiness directive (AD) 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010), and adding the following new AD: Embraer S.A.: Docket No. FAA–2012–0590; Directorate Identifier 2011–NM–112–AD. (a) Comments Due Date We must receive comments by July 23, 2012. (b) Affected ADs This AD supersedes AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010). (c) Applicability (1) This AD applies to Embraer S.A. Model ERJ 190–100 STD, –100 LR, and –100 IGW airplanes; and Model ERJ 190–200 STD, –200 LR, and –200 IGW airplanes; certificated in any category; all serial numbers. (2) This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval of an alternative method of compliance (AMOC) according to paragraph (j)(1) of this AD. The request should include a description of changes to the required actions that will PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 ensure the continued operational safety of the airplane. (d) Subject Air Transport Association (ATA) of America Code 52, Doors; 53, Fuselage; 54, Nacelles/Pylons; 55, Stabilizers; 57, Wings; 71, Powerplant; and 78, Engine Exhaust. (e) Reason This AD was prompted by reports of cracks in some of the structural components of the airplane. We are issuing this AD since failure to inspect these structural components according to the new ALS tasks, thresholds, and intervals could prevent a timely detection of fatigue cracking, which if not properly addressed, could result in reduced structural integrity of the airplane. (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) Restated Actions and Compliance This paragraph restates the actions required by paragraph (f) of AD 2010–11–14, Amendment 39 16319 (75 FR 30277, June 1, 2010). (1) Within 90 days after July 6, 2010 (the effective date of AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010)), revise the Airworthiness Limitation Section (ALS) of the Instructions for Continued Airworthiness (ICA) to include the tasks specified in table 1 of this AD. These tasks are identified in EMBRAER Temporary Revision (TR) 2–5, dated December 6, 2007; and EMBRAER TR 2–6, dated February 12, 2008; to Appendix A, Part 2, Airworthiness Limitation Inspections (ALI)—Structures, of the EMBRAER 190 Maintenance Review Board Report (MRBR), MRB–1928. Note 1 to paragraph (g)(1) of this AD: The actions required by paragraph (g)(1) of this AD may be done by inserting a copy of EMBRAER TR 2–5 and TR 2–6 into the ALS of the EMBRAER 190 MRBR, MRB–1928. When these TRs have been included in general revisions of the EMBRAER 190 MRBR, MRB–1928, the general revisions may be inserted, provided the relevant information in the general revision is identical to that in EMBRAER TR 2–5 and TR 2–6, and these TRs may be removed. (2) The initial compliance times for the tasks specified in EMBRAER TR 2–5, dated December 6, 2007; and EMBRAER TR 2–6, dated February 12, 2008; to Appendix A, Part 2, Airworthiness Limitation Inspections (ALI)—Structures, of the EMBRAER 190 MRBR, MRB–1928; start at the later of the times specified in paragraphs (g)(2)(i) and (g)(2)(ii) of this AD. For certain tasks, the compliance times depend on the premodification and post-modification condition of the associated service bulletin, as specified in the ‘‘Applicability’’ column of these TRs. (i) Within the applicable threshold times specified in the TRs specified in table 1 of this AD. (ii) At the applicable compliance time specified in table 1 of this AD.

Airworthiness Directives; Embraer S.A. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede an existing airworthiness directive 
(AD) that applies to all Model ERJ 190-100

[[Page 33335]]

STD, -100 LR, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 
LR, and -200 IGW airplanes. The existing AD currently requires revising 
the maintenance program to incorporate modifications in the 
Airworthiness Limitation Section (ALS) of the Embraer S.A. ERJ 190 
Maintenance Review Board Report (MRBR). Since we issued that AD, new 
inspection tasks and their respective thresholds and intervals have 
been issued. This proposed AD would require revising the maintenance 
program to incorporate modifications in the Airworthiness Limitation 
Section (ALS) of the Embraer S.A. ERJ 190 Maintenance Review Board 
Report (MRBR) to include new inspection tasks and their respective 
thresholds and intervals. We are proposing this AD since failure to 
inspect these structural components according to the new ALS tasks, 
thresholds, and intervals could prevent a timely detection of fatigue 
cracking, which if not properly addressed, could result in reduced 
structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by July 23, 2012.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Portal: Go to https://www.regulations.gov. Follow the instructions for submitting comments.

Discussion

    On May 13, 2010, we issued AD 2010-11-14, Amendment 39-16319 (75 FR 
30277, June 1, 2010). That AD required actions intended to address an 
unsafe condition on the products listed above.
    Since we issued AD 2010-11-14, Amendment 39-16319 (75 FR 30277, 
June 1, 2010), the Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o 
Civil (ANAC), which is the airworthiness authority for Brazil, has 
issued Brazilian Airworthiness Directives 2010-08-03, dated September 
20, 2010, and 2011-05-04, dated June 16, 2011 (referred to after this 
as ``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    During the airplane full scale fatigue test, cracks were found 
in some structural components of the airplane. Analysis of these 
cracks resulted in modifications on the Airworthiness Limitation 
Section (ALS) of Embraer ERJ 190 Maintenance Review Board Report 
(MRBR), to include new inspections tasks and its respective 
thresholds and intervals.
    Failure to inspect these structural components, according to the 
new tasks, thresholds and intervals, could prevent a timely 
detection of fatigue cracking. These cracks, if not properly 
addressed, could adversely affect the structural integrity of the 
airplane.
    Since this condition may occur in other airplanes of the same 
type and affects flight safety, a corrective action is required. 
Thus, sufficient reason exists to request compliance with this 
[ANAC] AD in the indicated time limit.

The required action is revising the maintenance program to incorporate 
new structural inspection requirements. You may obtain further 
information by examining the MCAI in the AD docket.

Relevant Service Information

    Embraer S.A. has issued Part 2--Airworthiness Limitation 
Inspections (ALI)--Structures, of Appendix A, Airworthiness Limitations 
(AL), of the EMBRAER 190 Maintenance Review Board Report, MRB-1928, 
Revision 5, dated November 11, 2010; and Temporary Revision (TR) 5-1, 
dated February 11, 2011, to Part 2--Airworthiness Limitation 
Inspections (ALI)--Structures, of Appendix A, Airworthiness Limitations 
(AL), of the EMBRAER 190 Maintenance Review Board Report, MRB-1928, 
Revision 5, dated November 11, 2010. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.

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.

Correction To Restate Table 1 of AD 2010-11-14, Amendment 39-16319 (75 
FR 30277, June 1, 2010)

    Table 1 of AD 2010-11-14, Amendment 39-16319 (75 FR 30277, June 1, 
2010), contains a reference to EMBRAER Temporary Revision (TR) 2-6, 
dated December 12, 2008, to Part 2--Airworthiness Limitation 
Inspections (ALI)--Structures, of Appendix A, Airworthiness Limitations 
(AL), of the EMBRAER 190 Maintenance Review

[[Page 33336]]

Board Report, MRB-1928. We have determined that the correct date for 
that TR should be February 12, 2008. That information is reflected in 
table 1 of this proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 88 products of U.S. registry.
    The actions that are required by AD 2010-11-14, Amendment 39-16319 
(75 FR 30277, June 1, 2010), and retained in this proposed AD take 
about 1 work-hour per product, at an average labor rate of $85 per work 
hour. Based on these figures, the estimated cost of the currently 
required actions is $85 per product.
    We estimate that it would take about 1 work-hour per product to 
comply with the new 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 $7,480, or $85 per 
product.

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 removing airworthiness directive 
(AD) 2010-11-14, Amendment 39-16319 (75 FR 30277, June 1, 2010), and 
adding the following new AD:

Embraer S.A.: Docket No. FAA-2012-0590; Directorate Identifier 2011-
NM-112-AD.

(a) Comments Due Date

    We must receive comments by July 23, 2012.

(b) Affected ADs

    This AD supersedes AD 2010-11-14, Amendment 39-16319 (75 FR 
30277, June 1, 2010).

(c) Applicability

    (1) This AD applies to Embraer S.A. Model ERJ 190-100 STD, -100 
LR, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and 
-200 IGW airplanes; certificated in any category; all serial 
numbers.
    (2) This AD requires revisions to certain operator maintenance 
documents to include new actions (e.g., inspections). Compliance 
with these actions is required by 14 CFR 91.403(c). For airplanes 
that have been previously modified, altered, or repaired in the 
areas addressed by this AD, the operator may not be able to 
accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval of an alternative method of compliance (AMOC) 
according to paragraph (j)(1) of this AD. The request should include 
a description of changes to the required actions that will ensure 
the continued operational safety of the airplane.

(d) Subject

    Air Transport Association (ATA) of America Code 52, Doors; 53, 
Fuselage; 54, Nacelles/Pylons; 55, Stabilizers; 57, Wings; 71, 
Powerplant; and 78, Engine Exhaust.

(e) Reason

    This AD was prompted by reports of cracks in some of the 
structural components of the airplane. We are issuing this AD since 
failure to inspect these structural components according to the new 
ALS tasks, thresholds, and intervals could prevent a timely 
detection of fatigue cracking, which if not properly addressed, 
could result in reduced structural integrity of the airplane.

(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) Restated Actions and Compliance

    This paragraph restates the actions required by paragraph (f) of 
AD 2010-11-14, Amendment 39 16319 (75 FR 30277, June 1, 2010).
    (1) Within 90 days after July 6, 2010 (the effective date of AD 
2010-11-14, Amendment 39-16319 (75 FR 30277, June 1, 2010)), revise 
the Airworthiness Limitation Section (ALS) of the Instructions for 
Continued Airworthiness (ICA) to include the tasks specified in 
table 1 of this AD. These tasks are identified in EMBRAER Temporary 
Revision (TR) 2-5, dated December 6, 2007; and EMBRAER TR 2-6, dated 
February 12, 2008; to Appendix A, Part 2, Airworthiness Limitation 
Inspections (ALI)--Structures, of the EMBRAER 190 Maintenance Review 
Board Report (MRBR), MRB-1928.

    Note 1 to paragraph (g)(1) of this AD:  The actions required by 
paragraph (g)(1) of this AD may be done by inserting a copy of 
EMBRAER TR 2-5 and TR 2-6 into the ALS of the EMBRAER 190 MRBR, MRB-
1928. When these TRs have been included in general revisions of the 
EMBRAER 190 MRBR, MRB-1928, the general revisions may be inserted, 
provided the relevant information in the general revision is 
identical to that in EMBRAER TR 2-5 and TR 2-6, and these TRs may be 
removed.

    (2) The initial compliance times for the tasks specified in 
EMBRAER TR 2-5, dated December 6, 2007; and EMBRAER TR 2-6, dated 
February 12, 2008; to Appendix A, Part 2, Airworthiness Limitation 
Inspections (ALI)--Structures, of the EMBRAER 190 MRBR, MRB-1928; 
start at the later of the times specified in paragraphs (g)(2)(i) 
and (g)(2)(ii) of this AD. For certain tasks, the compliance times 
depend on the pre-modification and post-modification condition of 
the associated service bulletin, as specified in the 
``Applicability'' column of these TRs.
    (i) Within the applicable threshold times specified in the TRs 
specified in table 1 of this AD.
    (ii) At the applicable compliance time specified in table 1 of 
this AD.
