Airworthiness Directives; Airbus Model A318, A319, A320, and A321 
Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above that would supersede an existing AD. This 
proposed 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

[[Page 16583]]

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. The proposed AD would require actions that 
are intended to address the unsafe condition described in the MCAI.

Discussion

    On September 21, 2007, we issued AD 2007-20-05, Amendment 39-15215 
(72 FR 56262, October 3, 2007). That AD required operators of Airbus 
Model A318, A319, A320, and A321 series airplanes to revise the 
Airworthiness Limitations Section (ALS) of the Instructions for 
Continued Airworthiness to incorporate Sub-part 1-2, ``Life Limits,'' 
and Sub-part 1-3, ``Demonstrated Fatigue Lives,'' of Airbus A318/A319/
A320/A321 ALS Part 1--Safe Life Airworthiness Limitation Items, dated 
February 28, 2006, and for certain airplanes, Airbus A318/A319/A320/
A321 Airworthiness Limitation Items, Document AI/SE-M4/95A.0252/96, 
Issue 7, dated December 2005; Issue 08, dated March 2006; or Issue 09, 
dated November 2006. These actions were intended to address an unsafe 
condition on the products listed above.
    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 AD has been revised to clarify the special compliance times 
defined in Table 1 of this AD.

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

Relevant Service Information

    Airbus has issued A318/A319/A320/A321 Airworthiness Limitation 
Items, Document AI/SE-M4/95A.0252/96, Issue 10, dated October 2009; and 
A319 Corporate Jet Airworthiness Limitation Items, Document reference 
AI/SE-M2/95A.1038/99, Issue 02, dated March 2009. A319 Corporate Jet 
Airworthiness Limitation Items, Document AI/SE-M2/95A.1038/99, Issue 
02, dated March 2009, states that the limitations for the Model A319 
corporate jets are specified in Airbus A318/A319/A320/A321 
Airworthiness Limitation Items, Document AI/SE-M4/95A.0252/96, Issue 
10, dated October 2009. 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

[[Page 16584]]

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.

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 proposed 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 proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 729 products of U.S. registry.
    The actions that are required by AD 2007-20-05 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 $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 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.

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

Airbus: Docket No. FAA-2011-0257; Directorate Identifier 2010-NM-
122-AD.

Comments Due Date

    (a) We must receive comments by May 9, 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; 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.

FAA AD Differences

    Note 3:  This AD differs from the MCAI and/or service 
information as follows: EASA AD 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. However,

[[Page 16587]]

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.

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/ACO, 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:  [email protected]. 
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.
