Download as PDF mstockstill on DSK4VPTVN1PROD with RULES 42024 Federal Register / Vol. 76, No. 137 / Monday, July 18, 2011 / Rules and Regulations applicant must establish by test, analysis, or a combination of both, that each rotor will not burst when operated in the engine for 5 minutes at whichever of the conditions defined in paragraph (b) of this section is the most critical with respect to the integrity of such a rotor. (1) Test rotors used to demonstrate compliance with this section that do not have the most adverse combination of material properties and dimensional tolerances must be tested at conditions which have been adjusted to ensure the minimum specification rotor possesses the required overspeed capability. This can be accomplished by increasing test speed, temperature, and/or loads. (2) When an engine test is being used to demonstrate compliance with the overspeed conditions listed in paragraph (b)(3) or (b)(4) of this section and the failure of a component or system is sudden and transient, it may not be possible to operate the engine for 5 minutes after the failure. Under these circumstances, the actual overspeed duration is acceptable if the required maximum overspeed is achieved. (b) When determining the maximum overspeed condition applicable to each rotor in order to comply with paragraphs (a) and (c) of this section, the applicant must evaluate the following rotor speeds taking into consideration the part’s operating temperatures and temperature gradients throughout the engine’s operating envelope: (1) 120 percent of the maximum permissible rotor speed associated with any of the engine ratings except oneengine-inoperative (OEI) ratings of less than 21⁄2 minutes. (2) 115 percent of the maximum permissible rotor speed associated with any OEI ratings of less than 21⁄2 minutes. (3) 105 percent of the highest rotor speed that would result from either: (i) The failure of the component or system which, in a representative installation of the engine, is the most critical with respect to overspeed when operating at any rating condition except OEI ratings of less than 21⁄2 minutes, or (ii) The failure of any component or system in a representative installation of the engine, in combination with any other failure of a component or system that would not normally be detected during a routine pre-flight check or during normal flight operation, that is the most critical with respect to overspeed, except as provided by paragraph (c) of this section, when operating at any rating condition except OEI ratings of less than 21⁄2 minutes. (4) 100 percent of the highest rotor speed that would result from the failure of the component or system which, in VerDate Mar<15>2010 15:32 Jul 15, 2011 Jkt 223001 a representative installation of the engine, is the most critical with respect to overspeed when operating at any OEI rating of less than 21⁄2 minutes. (c) The highest overspeed that results from a complete loss of load on a turbine rotor, except as provided by paragraph (f) of this section, must be included in the overspeed conditions considered by paragraphs (b)(3)(i), (b)(3)(ii), and (b)(4) of this section, regardless of whether that overspeed results from a failure within the engine or external to the engine. The overspeed resulting from any other single failure must be considered when selecting the most limiting overspeed conditions applicable to each rotor. Overspeeds resulting from combinations of failures must also be considered unless the applicant can show that the probability of occurrence is not greater than extremely remote (probability range of 10¥7 to 10¥9 per engine flight hour). (d) In addition, the applicant must demonstrate that each fan, compressor, turbine, and turbosupercharger rotor complies with paragraphs (d)(1) and (d)(2) of this section for the maximum overspeed achieved when subjected to the conditions specified in paragraphs (b)(3) and (b)(4) of this section. The applicant must use the approach in paragraph (a) of this section which specifies the required test conditions. (1) Rotor Growth must not cause the engine to: (i) Catch fire, (ii) Release high-energy debris through the engine casing or result in a hazardous failure of the engine casing, (iii) Generate loads greater than those ultimate loads specified in § 33.23(a), or (iv) Lose the capability of being shut down. (2) Following an overspeed event and after continued operation, the rotor may not exhibit conditions such as cracking or distortion which preclude continued safe operation. (e) The design and functioning of engine control systems, instruments, and other methods not covered under § 33.28 must ensure that the engine operating limitations that affect turbine, compressor, fan, and turbosupercharger rotor structural integrity will not be exceeded in service. (f) Failure of a shaft section may be excluded from consideration in determining the highest overspeed that would result from a complete loss of load on a turbine rotor if the applicant: (1) Identifies the shaft as an engine life-limited-part and complies with § 33.70. (2) Uses material and design features that are well understood and that can be PO 00000 Frm 00032 Fmt 4700 Sfmt 4700 analyzed by well-established and validated stress analysis techniques. (3) Determines, based on an assessment of the environment surrounding the shaft section, that environmental influences are unlikely to cause a shaft failure. This assessment must include complexity of design, corrosion, wear, vibration, fire, contact with adjacent components or structure, overheating, and secondary effects from other failures or combination of failures. (4) Identifies and declares, in accordance with § 33.5, any assumptions regarding the engine installation in making the assessment described above in paragraph (f)(3) of this section. (5) Assesses, and considers as appropriate, experience with shaft sections of similar design. (6) Does not exclude the entire shaft. (g) If analysis is used to meet the overspeed requirements, then the analytical tool must be validated to prior overspeed test results of a similar rotor. The tool must be validated for each material. The rotor being certified must not exceed the boundaries of the rotors being used to validate the analytical tool in terms of geometric shape, operating stress, and temperature. Validation includes the ability to accurately predict rotor dimensional growth and the burst speed. The predictions must also show that the rotor being certified does not have lower burst and growth margins than rotors used to validate the tool. Issued in Washington, DC, on June 30, 2011. J.

ACTION: Final rule. AGENCY: We are superseding an existing airworthiness directive (AD) SUMMARY: E:\FR\FM\18JYR1.SGM 18JYR1 Federal Register / Vol. 76, No. 137 / Monday, July 18, 2011 / Rules and Regulations that applies to the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: * * * * * The issue 10 of Airbus A318/A319/A320/ A321 ALI [Airworthiness Limitation Items] Document and issue 2 of Airbus A319 Corporate Jet ALI Document introduce more restrictive maintenance requirements/ airworthiness limitations. Failure to comply with this issue 10 constitutes an unsafe condition. mstockstill on DSK4VPTVN1PROD with RULES * * * * * The unsafe condition is fatigue cracking, accidental damage, or corrosion in principal structural elements and possible failure of certain life limited parts, which could result in reduced structural integrity of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective August 22, 2011. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 22, 2011. The Director of the Federal Register previously approved the incorporation by reference of certain other publications, listed in this AD as of November 7, 2007 (72 FR 56262, October 3, 2007). ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on March 24, 2011 (76 FR 16582), and proposed to supersede AD 2007–20–05, Amendment 39–15215 (72 FR 56262, October 3, 2007). Since we issued AD 2007–20–05, we have determined that more restrictive VerDate Mar<15>2010 15:32 Jul 15, 2011 Jkt 223001 limitations are necessary. We have also added Model A318–121 and –122 airplanes to the applicability. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2010–0071R1, dated May 28, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: The airworthiness limitations are currently included in Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS). The airworthiness limitations applicable to the Damage Tolerant Airworthiness Limitation Items (DT ALI) are currently given in Airbus A318/A319/A320/A321 ALI Document reference AI/SE–M4/95A.0252/96 and Airbus A319 Corporate Jet ALI Document reference AI/SE–M2/95A.1038/99, which are approved by the European Aviation Safety Agency (EASA) and referenced in Airbus Airworthiness Limitations Section (ALS) Part 2. The issue 10 of Airbus A318/A319/A320/ A321 ALI Document and issue 2 of Airbus A319 Corporate Jet ALI Document introduce more restrictive maintenance requirements/ airworthiness limitations. Failure to comply with this issue 10 constitutes an unsafe condition. EASA AD 2010–0071 retains the requirements of EASA AD 2006–0165, which is superseded, and requires the implementation of more restrictive maintenance requirements/airworthiness limitations as specified in Airbus A318/ A319/A320/A321 ALI Document reference AI/SE–M4/95A.0252/96 issue 10 and Airbus A319 Corporate Jet ALI Document reference AI/SE–M2/95A.1038/99. This [EASA] AD has been revised to clarify the special compliance times defined in Table 1 of this [EASA] AD. You may obtain further information by examining the MCAI in the AD docket. 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. Revision to Airworthiness Limitation Items Document Airbus has issued A318/A319/A320/ A321 Airworthiness Limitation Items, Document AI/SE–M4/95A.0252/96, Issue 11, dated September 2010. Issue 11 of Airbus A318/A319/A320/A321 Airworthiness Limitation Items, Document AI/SE–M4/95A.0252/96 does not add any additional burden on the operator. We have revised paragraphs (j) and (k), table 1, and Note 3, in this final rule to require compliance in accordance with Airbus A318/A319/ A320/A321 Airworthiness Limitation PO 00000 Frm 00033 Fmt 4700 Sfmt 4700 42025 Items, Document AI/SE–M4/95A.0252/ 96, Issue 10, dated October 2009; or Issue 11, dated September 2010. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD with the changes described previously. We determined that these changes will not increase the economic burden on any operator or increase the scope of the AD. Differences Between This 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 our FAA policies. Any such differences are highlighted in a Note within the AD. Costs of Compliance We estimate that this AD will affect about 729 products of U.S. registry. The actions that are required by AD 2007–20–05 and retained in this 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 will take about 1 work-hour per product to comply with the new basic requirements of this AD. The average labor rate is $85 per workhour. Based on these figures, we estimate the cost of the AD on U.S. operators to be $61,965, 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 E:\FR\FM\18JYR1.SGM 18JYR1 42026 Federal Register / Vol. 76, No. 137 / Monday, July 18, 2011 / Rules and Regulations 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. Examining the AD Docket You may examine the AD docket on the Internet at https:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. 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: mstockstill on DSK4VPTVN1PROD with RULES 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 Amendment 39–15215 (72 FR ■ VerDate Mar<15>2010 15:32 Jul 15, 2011 Jkt 223001 56262, October 3, 2007) and adding the following new AD: 2011–14–06 Airbus: Amendment 39–16741. Docket No. FAA–2011–0257; Directorate Identifier 2010–NM–122–AD. Effective Date (a) This airworthiness directive (AD) becomes effective August 22, 2011. Affected ADs (b) This AD supersedes AD 2007–20–05, Amendment 39–15215. Applicability (c) This AD applies to all Airbus Model A318–111, –112, –121, and –122 airplanes; Model A319–111, –112, –113, –114, –115, –131, –132, and –133 airplanes; Model A320–111, –211, –212, –214, –231, –232, and –233 airplanes; and Model A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes; certificated in any category. 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 (n) of this AD. The request should include a description of changes to the required inspections that will ensure the continued damage tolerance of the affected structure. The FAA has provided guidance for this determination in Advisory Circular (AC) 25.1529–1. Subject (d) Air Transport Association (ATA) of America Code 05: Wings. Reason (e) The mandatory continuing airworthiness information (MCAI) states: * * * * * The issue 10 of Airbus A318/A319/A320/ A321 ALI [Airworthiness Limitation Items] Document and issue 2 of Airbus A319 Corporate Jet ALI Document introduce more restrictive maintenance requirements/ airworthiness limitations. Failure to comply with this issue 10 constitutes an unsafe condition. * * * * * The unsafe condition is fatigue cracking, accidental damage, or corrosion in principal structural elements and possible 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.

The MCAI describes the unsafe condition as: Federal Aviation Administration A specific failure case of the THSA [trimmable horizontal stabilizer actuator] upper primary attachment, which may result in a loading of the upper secondary attachment, has been identified by analysis. Primary load path failure can be caused by bearing migration from the upper attachment gimbal by failure or loss of a retention bolt. In case of failure of the THSA upper primary attachment, the THSA upper secondary attachment would engage. Because the upper attachment secondary load path can only withstand the loads for a limited period of time, the condition where it would be engaged could lead, if not detected, to the failure of the secondary load path, which would likely result in loss of control of the aeroplane. 14 CFR Part 39 [Docket No. FAA–2011–0309; Directorate Identifier 2010–NM–255–AD; Amendment 39–16755; AD 2011–15–08] RIN 2120–AA64 Airworthiness Directives; Airbus Model A300 B4–600, B4–600R, and F4–600R Series Airplanes, and Model A300 C4– 605R Variant F Airplanes (Collectively Called A300–600 Series Airplanes); and Model A310 Series Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT).

SUMMARY: We are superseding an existing airworthiness directive (AD)

[[Page 42025]]

that applies to the products listed above. This AD results from 
mandatory continuing airworthiness information (MCAI) originated by an 
aviation authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as:

* * * * *
    The issue 10 of Airbus A318/A319/A320/A321 ALI [Airworthiness 
Limitation Items] Document and issue 2 of Airbus A319 Corporate Jet 
ALI Document introduce more restrictive maintenance requirements/
airworthiness limitations. Failure to comply with this issue 10 
constitutes an unsafe condition.
* * * * *
The unsafe condition is fatigue cracking, accidental damage, or 
corrosion in principal structural elements and possible failure of 
certain life limited parts, which could result in reduced structural 
integrity of the airplane. We are issuing this AD to require actions to 
correct the unsafe condition on these products.

DATES: This AD becomes effective August 22, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 22,

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on March 24, 2011 (76 
FR 16582), and proposed to supersede AD 2007-20-05, Amendment 39-15215 
(72 FR 56262, October 3, 2007).
    Since we issued AD 2007-20-05, we have determined that more 
restrictive limitations are necessary. We have also added Model A318-
121 and -122 airplanes to the applicability. The European Aviation 
Safety Agency (EASA), which is the Technical Agent for the Member 
States of the European Community, has issued EASA Airworthiness 
Directive 2010-0071R1, dated May 28, 2010 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    The airworthiness limitations are currently included in Airbus 
A318/A319/A320/A321 Airworthiness Limitations Section (ALS).
    The airworthiness limitations applicable to the Damage Tolerant 
Airworthiness Limitation Items (DT ALI) are currently given in 
Airbus A318/A319/A320/A321 ALI Document reference AI/SE-M4/95A.0252/
96 and Airbus A319 Corporate Jet ALI Document reference AI/SE-M2/
95A.1038/99, which are approved by the European Aviation Safety 
Agency (EASA) and referenced in Airbus Airworthiness Limitations 
Section (ALS) Part 2.
    The issue 10 of Airbus A318/A319/A320/A321 ALI Document and 
issue 2 of Airbus A319 Corporate Jet ALI Document introduce more 
restrictive maintenance requirements/airworthiness limitations. 
Failure to comply with this issue 10 constitutes an unsafe 
condition.
    EASA AD 2010-0071 retains the requirements of EASA AD 2006-0165, 
which is superseded, and requires the implementation of more 
restrictive maintenance requirements/airworthiness limitations as 
specified in Airbus A318/A319/A320/A321 ALI Document reference AI/
SE-M4/95A.0252/96 issue 10 and Airbus A319 Corporate Jet ALI 
Document reference AI/SE-M2/95A.1038/99.
    This [EASA] AD has been revised to clarify the special 
compliance times defined in Table 1 of this [EASA] AD.

You may obtain further information by examining the MCAI in the AD 
docket.

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.

Revision to Airworthiness Limitation Items Document

    Airbus has issued A318/A319/A320/A321 Airworthiness Limitation 
Items, Document AI/SE-M4/95A.0252/96, Issue 11, dated September 2010. 
Issue 11 of Airbus A318/A319/A320/A321 Airworthiness Limitation Items, 
Document AI/SE-M4/95A.0252/96 does not add any additional burden on the 
operator. We have revised paragraphs (j) and (k), table 1, and Note 3, 
in this final rule to require compliance in accordance with Airbus 
A318/A319/A320/A321 Airworthiness Limitation Items, Document AI/SE-M4/
95A.0252/96, Issue 10, dated October 2009; or Issue 11, dated September 
2010.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously. We determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

Differences Between This 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 our FAA policies. Any such differences 
are highlighted in a Note within the AD.

Costs of Compliance

    We estimate that this AD will affect about 729 products of U.S. 
registry.
    The actions that are required by AD 2007-20-05 and retained in this 
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 will take about 1 work-hour per product to 
comply with the new basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of the AD on U.S. operators to be $61,965, 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

[[Page 42026]]

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.

Examining the AD Docket

    You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

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 removing Amendment 39-15215 (72 FR 
56262, October 3, 2007) and adding the following new AD:

2011-14-06 Airbus: Amendment 39-16741. Docket No. FAA-2011-0257; 
Directorate Identifier 2010-NM-122-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective August 
22, 2011.

Affected ADs

    (b) This AD supersedes AD 2007-20-05, Amendment 39-15215.

Applicability

    (c) This AD applies to all Airbus Model A318-111, -112, -121, 
and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -
132, and -133 airplanes; Model A320-111, -211, -212, -214, -231, -
232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, 
-213, -231, and -232 airplanes; certificated in any category.

    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 (n) of this AD. The request should include a 
description of changes to the required inspections that will ensure 
the continued damage tolerance of the affected structure. The FAA 
has provided guidance for this determination in Advisory Circular 
(AC) 25.1529-1.

Subject

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

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
* * * * *
    The issue 10 of Airbus A318/A319/A320/A321 ALI [Airworthiness 
Limitation Items] Document and issue 2 of Airbus A319 Corporate Jet 
ALI Document introduce more restrictive maintenance requirements/
airworthiness limitations. Failure to comply with this issue 10 
constitutes an unsafe condition.
* * * * *
The unsafe condition is fatigue cracking, accidental damage, or 
corrosion in principal structural elements and possible 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

    Note 2: New ALI Task 572050 refers to the outer wing dry bay and 
is comprised of extracts from three ALI Tasks: 572004, 572020 and 
572053. The threshold of ALI Task 572050 for the whole dry bay area 
is that of the lowest threshold of the source ALI tasks, i.e., that 
of ALI Task 572053.

No Alternative Life Limits, Inspections, or Inspection Intervals

    (l) After the actions specified in paragraphs (g) and (h) of 
this AD have been accomplished, no alternative life limits, 
inspections, or inspection intervals may be used, except as provided 
by paragraphs (i) and (m) of this AD, and except as required by 
paragraph (j) of this AD.
    (m) After the actions specified in paragraph (j) of this AD have 
been accomplished, no alternative life limits, inspections, or 
inspection intervals may be used.

FAA AD Differences

    Note 3: This AD differs from the MCAI and/or service information 
as follows: European Aviation Safety Agency (EASA) AD 2010-0071R1, 
dated May 28, 2010, requires operators to comply with the 
limitations specified in Airbus A318/A319/A320/A321 Airworthiness 
Limitation Items, Document AI/SE-M4/95A.0252/96, Issue 10, dated 
October 2009; or Airbus A319 Corporate Jet Airworthiness Limitation 
Items, Document AI/SE-M2/95A.1038/99, Issue 02, dated March 2009; as 
applicable. This AD requires incorporating Airbus A318/A319/A320/
A321 Airworthiness Limitation Items, Document AI/SE-M4/95A.0252/96, 
Issue 10, dated October 2009; or Issue 11, dated September 2010. 
Additionally, this AD does not require incorporating Airbus A319 
Corporate Jet Airworthiness Limitation Items, Document AI/SE-M2/
95A.1038/99, Issue 02, dated March 2009, because that ALI only 
specifies compliance with the limitations specified in Airbus A318/
A319/A320/A321 Airworthiness Limitation Items, Document AI/SE-M4/
95A.0252/96, Issue 10, dated October 2009; or Issue 11, dated 
September 2010.

Other FAA AD Provisions

    (n) 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. In accordance with 14 CFR 
39.19, send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Branch, send it to Attn: Tim Dulin, 
Aerospace Engineer, International Branch, ANM-116, Transport 
Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 
98057-3356; telephone (425) 227-2141; fax (425) 227-1149. 
Information may be e-mailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
local flight standards district office/certificate holding district 
office. The AMOC approval letter must specifically reference this 
AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
