SUPPLEMENTARY INFORMATION: jdjones on DSK8KYBLC1PROD with RULES Discussion The European Aviation Safety Agency (EASA), which is the aviation authority for the Member States of the European Community, has issued EASA Airworthiness Directives 2010–0131, dated June 28, 2010 and EASA AD 2009–0192, dated August 28, 2009 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI (EASA AD 2009–0192) states: Performing some quality tests on material, Airbus found that some 300M steel forgings used to manufacture certain landing gear components were below specification limits. Adapted airworthiness limitations were introduced in Airbus A340 Airworthiness Limitations Section (ALS) Part 1 ‘‘Safe Life Airworthiness Limitation Items (SL ALI)’’ for different source route codes. A new source route (S3) has since been investigated and has led to another set of adapted airworthiness limitations for affected main fittings. In addition, further tests based on a new method for damage load selection led to the limitation changes for A340–500/–600 centre landing gear main fitting part number (P/N) 50–1105236–01 and P/N 1105296–00. This [EASA] AD introduces more restrictive life limitations for several landing gear components. The MCAI (EASA AD 2010–0131) describes the unsafe condition as: The airworthiness limitations are currently distributed in the Airbus A330 and A340 Airworthiness Limitations Section (ALS). VerDate Mar<15>2010 15:22 Feb 14, 2011 Jkt 223001 The airworthiness limitations applicable to the Safe Life Airworthiness Limitation Items (SL ALI) are given in Airbus A330 and A340 ALS Part 1, which are approved by the European Aviation Safety Agency (EASA). The revision 04 of Airbus A330 and A340 ALS Part 1 introduces more restrictive maintenance requirements and/or airworthiness limitations as specified in Airbus A330 and A340 ALS Part 1 revision 04. This new [EASA] AD supersedes EASA AD 2007–0300, EASA AD 2008–0152 and EASA AD 2009–0191 and requires the implementation of the new or more restrictive maintenance requirements and/or airworthiness limitations as specified in Airbus A330 and A340 ALS Part 1 revision 04. The unsafe condition is failure of certain life-limited parts, which could result in reduced structural integrity of the airplane. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued A340 ALS Part 1, Safe Life Airworthiness Limitation Items Revision 05, dated July 29, 2010. This document provides for mandatory replacement times, structural inspection intervals, and related structural inspection procedures or other procedures (e.g., modifications). The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. Other Relevant Rulemaking On April 20, 2006, we issued AD 2006–09–07, Amendment 39–14577 (71 FR 25919, May 3, 2006), for all Airbus Model A330–200 and –300, and A340– 200 and –300 series airplanes, and A340–541 and –642 airplanes. That AD requires operators to revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate new information. That information includes, for all affected airplanes, decreased life limit values for certain components; and for Model A330–200 and –300 series airplanes, new inspections, compliance times, and new repetitive intervals to detect fatigue cracking, accidental damage, or corrosion in certain structures. That AD results from a revision to section 9–1 of the Airbus A330 and A340 maintenance planning documents (MPDs) for life limits/ monitored parts, and section 9–2 of the Airbus A330 MPD for airworthiness limitations items. Accomplishing the revision in paragraph (g) of this AD eliminates the need for the revision required by paragraph (f)(2) of AD 2006– 09–07 for Model A340 airplanes. PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 8613 FAA’s Determination and Requirements of This 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 issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. There are no products of this type currently registered in the United States. However, this rule is necessary to ensure that the described unsafe condition is addressed if any of these products are placed on the U.S. Register in the future. Differences Between the AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a Note within the AD. FAA’s Determination of the Effective Date Since there are currently no domestic operators of this product, notice and opportunity for public comment before issuing this AD are unnecessary. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2011–0039; Directorate Identifier 2010–NM–184– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. E:\FR\FM\15FER1.SGM 15FER1 8614 Federal Register / Vol. 76, No. 31 / Tuesday, February 15, 2011 / Rules and Regulations 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 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 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); and 3. 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 AD and placed it in the AD docket. jdjones on DSK8KYBLC1PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: VerDate Mar<15>2010 15:22 Feb 14, 2011 Jkt 223001 PART 39—AIRWORTHINESS DIRECTIVES airworthiness limitations as specified in Airbus A330 and A340 ALS Part 1 revision 04. 1. The authority citation for part 39 continues to read as follows: The unsafe condition is failure of certain lifelimited parts, which could result in reduced structural integrity of the airplane. ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: ■ 2011–04–05 Airbus: Amendment 39–16605. Docket No. FAA–2011–0039; Directorate Identifier 2010–NM–184–AD. Effective Date (a) This airworthiness directive (AD) becomes effective March 2, 2011. Affected ADs (b) This AD affects AD 2006–09–07, Amendment 39–14577. Applicability (c) This AD applies to Airbus Model A340– 211, –212, and –213 airplanes; A340–311, –312, and –313 airplanes; A340–541 airplanes; and A340–642 airplanes; certificated in any category; all manufacturer serial numbers. Note 1: This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (j)(1) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane. Subject (d) Air Transport Association (ATA) of America Code 05. Reason (e) The mandatory continuing airworthiness information (MCAI) (European Aviation Safety Agency (EASA) AD 2009– 0192) states: Performing some quality tests on material, Airbus found that some 300M steel forgings used to manufacture certain landing gear components were below specification limits. Adapted airworthiness limitations were introduced in Airbus A340 Airworthiness Limitations Section (ALS) Part 1 ‘‘Safe Life Airworthiness Limitation Items (SL ALI)’’ for different source route codes. * * * * * This [EASA] AD introduces more restrictive life limitations for several landing gear components. The MCAI (EASA AD 2010–0131) describes the unsafe condition as: * * * * * The revision 04 of Airbus A330 and A340 ALS Part 1 introduces more restrictive maintenance requirements and/or PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 Compliance (f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Revise the Maintenance Program (g) Within 3 months after the effective date of this AD: Revise the maintenance program by incorporating Airbus A340 ALS Part 1— Safe Life Airworthiness Limitation Items (SL ALI), Revision 05, dated July 29, 2010.

Alternative Intervals or Limits (h) Except as provided by paragraph (j)(1) of this AD, after accomplishing the actions specified in paragraph (g) of this AD, no alternative to the replacements, replacement intervals, or limitations specified in paragraph (g) of this AD may be used. Method of Compliance With Paragraph (f)(2) of AD 2006–09–07 (i) Doing the revision required by paragraph (g) of this AD terminates the requirements of paragraph (f)(2) of AD 2006– 09–07 for that Model A340 airplane only. FAA AD Differences Note 2: This AD differs from the MCAI and/or service information as follows: Although the MCAI specifies a compliance time of ‘‘from the effective date of this AD’’ for revising the maintenance program to incorporate Airbus A340 ALS Part 1—Safe Life Airworthiness Limitation Items, Revision 05, dated July 29, 2010; this AD requires the action be done within 3 months after the effective date of this AD. Other FAA AD Provisions (j) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM–116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

AGENCY: We are adopting a new airworthiness directive (AD) for certain Model 767 airplanes. This AD requires doing a detailed inspection for correct main track downstop assembly, thread protrusion, and damaged and missing parts of the main track downstop assemblies of the outboard slats, and related investigative and corrective actions if necessary. This AD also requires doing a detailed inspection for foreign objects, debris and damage to the wall of the track housing of the outboard slats, and corrective actions if necessary. This AD results from reports of broken bolts in the outboard slat main track downstop assembly. We are issuing this AD to detect and correct incorrectly installed main track downstop assemblies, which can allow the main track downstop hardware to fall into the track housing and cause a puncture in the track housing when the slat is retracted. This condition, if not corrected, could result in a fuel leak and an increased risk of fire. DATES: This AD is effective March 22, 2011.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain Model 767 airplanes. That NPRM was published in the Federal Register on April 8, 2010 (75 FR 17887). That NPRM proposed to require doing a detailed inspection for correct main track downstop assembly, thread protrusion, and damaged and missing parts of the main track downstop assemblies of the outboard slats, and related investigative and corrective actions if necessary. That proposed AD also proposed to require doing a detailed inspection for foreign objects debris and damage to the wall of the track housing of the outboard slats, and corrective actions if necessary. Relevant Service Information The NPRM referred to Boeing Special Attention Service Bulletin 767–57– 0118, dated October 8, 2009. We reviewed Boeing Special Attention Service Bulletin 767–57–0118, Revision 1, dated October 21, 2010. This service bulletin revision adds an option to inspect either the bolt or nut for looseness by applying torque to the main track downstop assembly nut or the bolt head, corrects a reference, and removes the references to slat numbers 6 and 7 in Appendix A. This service bulletin revision does not add any additional work for the affected airplanes. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received from the commenters. Request To Add Boeing Document D– 590 as Source of Additional Guidance American Airlines (AAL) requested that we specify that Boeing Document D–590 may be used as a source for acceptable fastener and material E:\FR\FM\15FER1.SGM 15FER1

airworthiness information (MCAI) originated by an aviation authority of 
another country to identify and correct an unsafe condition on an 
aviation product. The MCAI (European Aviation Safety Agency AD 2009-
0192) describes the unsafe condition as:

    Performing some quality tests on material, Airbus found that 
some 300M steel forgings used to manufacture certain landing gear 
components were below specification limits. Adapted airworthiness 
limitations were introduced in Airbus A340 Airworthiness Limitations 
Section (ALS) Part 1 ``Safe Life Airworthiness Limitation Items (SL 
ALI)'' for different source route codes.
* * * * *
    This [EASA] AD introduces more restrictive life limitations for 
several landing gear components.
    The MCAI (EASA AD 2010-0131) describes the unsafe condition as:
* * * * *
    The revision 04 of Airbus A330 and A340 ALS Part 1 introduces 
more restrictive maintenance requirements and/or airworthiness 
limitations as specified in Airbus A330 and A340 ALS Part 1 revision 
04.

The unsafe condition is failure of certain life-limited parts, which 
could result in reduced structural integrity of the airplane. This AD 
requires actions that are intended to address the unsafe condition 
described in the MCAI.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the aviation 
authority for the Member States of the European Community, has issued 
EASA Airworthiness Directives 2010-0131, dated June 28, 2010 and EASA 
AD 2009-0192, dated August 28, 2009 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI (EASA AD 2009-0192) states:

    Performing some quality tests on material, Airbus found that 
some 300M steel forgings used to manufacture certain landing gear 
components were below specification limits. Adapted airworthiness 
limitations were introduced in Airbus A340 Airworthiness Limitations 
Section (ALS) Part 1 ``Safe Life Airworthiness Limitation Items (SL 
ALI)'' for different source route codes.
    A new source route (S3) has since been investigated and has led 
to another set of adapted airworthiness limitations for affected 
main fittings.
    In addition, further tests based on a new method for damage load 
selection led to the limitation changes for A340-500/-600 centre 
landing gear main fitting part number (P/N) 50-1105236-01 and P/N 
1105296-00.
    This [EASA] AD introduces more restrictive life limitations for 
several landing gear components.
    The MCAI (EASA AD 2010-0131) describes the unsafe condition as:
    The airworthiness limitations are currently distributed in the 
Airbus A330 and A340 Airworthiness Limitations Section (ALS).
    The airworthiness limitations applicable to the Safe Life 
Airworthiness Limitation Items (SL ALI) are given in Airbus A330 and 
A340 ALS Part 1, which are approved by the European Aviation Safety 
Agency (EASA).
    The revision 04 of Airbus A330 and A340 ALS Part 1 introduces 
more restrictive maintenance requirements and/or airworthiness 
limitations as specified in Airbus A330 and A340 ALS Part 1 revision 
04.
    This new [EASA] AD supersedes EASA AD 2007-0300, EASA AD 2008-
0152 and EASA AD 2009-0191 and requires the implementation of the 
new or more restrictive maintenance requirements and/or 
airworthiness limitations as specified in Airbus A330 and A340 ALS 
Part 1 revision 04.

The unsafe condition is failure of certain life-limited parts, which 
could result in reduced structural integrity of the airplane. You may 
obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued A340 ALS Part 1, Safe Life Airworthiness 
Limitation Items Revision 05, dated July 29, 2010. This document 
provides for mandatory replacement times, structural inspection 
intervals, and related structural inspection procedures or other 
procedures (e.g., modifications). The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

Other Relevant Rulemaking

    On April 20, 2006, we issued AD 2006-09-07, Amendment 39-14577 (71 
FR 25919, May 3, 2006), for all Airbus Model A330-200 and -300, and 
A340-200 and -300 series airplanes, and A340-541 and -642 airplanes. 
That AD requires operators to revise the Airworthiness Limitations 
section of the Instructions for Continued Airworthiness to incorporate 
new information. That information includes, for all affected airplanes, 
decreased life limit values for certain components; and for Model A330-
200 and -300 series airplanes, new inspections, compliance times, and 
new repetitive intervals to detect fatigue cracking, accidental damage, 
or corrosion in certain structures. That AD results from a revision to 
section 9-1 of the Airbus A330 and A340 maintenance planning documents 
(MPDs) for life limits/monitored parts, and section 9-2 of the Airbus 
A330 MPD for airworthiness limitations items. Accomplishing the 
revision in paragraph (g) of this AD eliminates the need for the 
revision required by paragraph (f)(2) of AD 2006-09-07 for Model A340 
airplanes.

FAA's Determination and Requirements of This 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future.

Differences Between the AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the AD.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2011-0039; Directorate 
Identifier 2010-NM-184-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.

[[Page 8614]]

    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 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 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); and
    3. 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 AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by

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 AD:

2011-04-05 Airbus: Amendment 39-16605. Docket No. FAA-2011-0039; 
Directorate Identifier 2010-NM-184-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective March 2, 
2011.

Affected ADs

    (b) This AD affects AD 2006-09-07, Amendment 39-14577.

Applicability

    (c) This AD applies to Airbus Model A340-211, -212, and -213 
airplanes; A340-311, -312, and -313 airplanes; A340-541 airplanes; 
and A340-642 airplanes; certificated in any category; all 
manufacturer serial numbers.

    Note 1:  This AD requires revisions to certain operator 
maintenance documents to include new inspections. Compliance with 
these inspections is required by 14 CFR 91.403(c). For airplanes 
that have been previously modified, altered, or repaired in the 
areas addressed by these inspections, the operator may not be able 
to accomplish the inspections described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according 
to paragraph (j)(1) of this AD. The request should include a 
description of changes to the required inspections that will ensure 
the continued operational safety of the airplane.

Subject

    (d) Air Transport Association (ATA) of America Code 05.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
(European Aviation Safety Agency (EASA) AD 2009-0192) states:

    Performing some quality tests on material, Airbus found that 
some 300M steel forgings used to manufacture certain landing gear 
components were below specification limits. Adapted airworthiness 
limitations were introduced in Airbus A340 Airworthiness Limitations 
Section (ALS) Part 1 ``Safe Life Airworthiness Limitation Items (SL 
ALI)'' for different source route codes.
* * * * *
    This [EASA] AD introduces more restrictive life limitations for 
several landing gear components.
    The MCAI (EASA AD 2010-0131) describes the unsafe condition as:
* * * * *
    The revision 04 of Airbus A330 and A340 ALS Part 1 introduces 
more restrictive maintenance requirements and/or airworthiness 
limitations as specified in Airbus A330 and A340 ALS Part 1 revision 
04.

The unsafe condition is failure of certain life-limited parts, which 
could result in reduced structural integrity of the airplane.

Compliance

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

Revise the Maintenance Program

    (g) Within 3 months after the effective date of this AD: Revise 
the maintenance program by incorporating Airbus A340 ALS Part 1--
Safe Life Airworthiness Limitation Items (SL ALI), Revision 05, 
dated July 29, 2010. At the times specified in the Airbus A340 ALS 
Part 1--SL ALI, Revision 05, dated July 29, 2010, comply with all 
applicable maintenance requirements and associated airworthiness 
limitations specified in Airbus A340 ALS, Part 1--SL ALI, Revision 
05, dated July 29, 2010.

Alternative Intervals or Limits

    (h) Except as provided by paragraph (j)(1) of this AD, after 
accomplishing the actions specified in paragraph (g) of this AD, no 
alternative to the replacements, replacement intervals, or 
limitations specified in paragraph (g) of this AD may be used.

Method of Compliance With Paragraph (f)(2) of AD 2006-09-07

    (i) Doing the revision required by paragraph (g) of this AD 
terminates the requirements of paragraph (f)(2) of AD 2006-09-07 for 
that Model A340 airplane only.

FAA AD Differences

    Note 2: This AD differs from the MCAI and/or service information 
as follows: Although the MCAI specifies a compliance time of ``from 
the effective date of this AD'' for revising the maintenance program 
to incorporate Airbus A340 ALS Part 1--Safe Life Airworthiness 
Limitation Items, Revision 05, dated July 29, 2010; this AD requires 
the action be done within 3 months after the effective date of this 
AD.

Other FAA AD Provisions

    (j) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. Send information to ATTN:
