RIN 2120-AA64

Airworthiness Directives; Airbus Model A330 Airplanes and A340-
200 and -300 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. 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 aviation product. The MCAI describes the unsafe
condition as:

    All permanent fuselage skin * * * and lap joint doubler * * *
repair principles published in the SRM (Structural Repair Manual) *
* * have been replaced with Oct/05 Revision by updated, simplified
and harmonized repair principles.
    These updates led to the de-validation of some repairs and to
reassess the repair inspection requirements. This situation if not

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance
of ADs related to MCAI. This streamlined process will allow us to adopt
MCAI safety requirements in a more efficient manner and will reduce
safety risks to the public. This process continues to follow all FAA AD
issuance processes to meet legal, economic, Administrative Procedure
Act, and Federal Register requirements. We also continue to meet our
technical decision-making responsibilities to identify and correct
unsafe conditions on U.S.-certificated products.
    This proposed AD references the MCAI and related service
information that we considered in forming the engineering basis to
correct the unsafe condition. The proposed AD contains text copied from
the MCAI and for this reason might not follow our plain language
principles.

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-2007-
29334; Directorate Identifier 2006-NM-268-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 http://dms.dot.gov
, including any personal information you provide. We will

also post a report summarizing each substantive verbal contact we
receive about this proposed AD.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directives 2006-0332 and 2006-0333, both dated October
27, 2006 (referred to after this as ``the MCAI''), to correct an unsafe
condition for the specified products. The MCAI states:

    A review of the repair substantiations of the SRM (Structural
Repair Manual) has been done to take into account the latest
aircraft operational data (Aircraft Weight Variant and Fatigue
Flight Mission Profiles). As a result, all permanent fuselage skin
(Figure 202-210/213-214) and lap joint doubler (Figure 215-216)
repair principles published in the SRM chapter 53-00-11, Page Block
201 have been replaced with Oct/05 Revision by updated, simplified
and harmonized repair principles.
    These updates led to the de-validation of some repairs and to
reassess the repair inspection requirements. This situation if not
corrected, can affect the aircraft structural integrity with a
possible risk of decompression.
    In order to maintain the structural integrity, this
Airworthiness Directive (AD) renders mandatory the inspection of the
fuselage to identify possible permanent skin repairs and permanent
longitudinal lap joint repairs and to apply the associated
corrective actions.

    The corrective actions include contacting Airbus for repair/
inspection instructions, and repair, as applicable, for skin repairs or
longitudinal lap joint repairs that were done in accordance with the
repair principles in SRM chapter 53-00-11, Page Block 201, before
October 2005, or repairs that were done without using an individual
repair design approval sheet provided by Airbus. You may obtain further
information by examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Service Bulletins A330-53-3161, dated April 14,
2006; A330-53-3162, dated April 6, 2006; and Service Bulletins A340-53-
4166 and A340-53-4167, both dated April 6, 2006. 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.

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 9 products of U.S. registry. We also estimate that
it would take about 9 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $6,480, or $720 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); 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 proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Safety.

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

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

Airbus: Docket No. FAA-2007-29334; Directorate Identifier 2006-NM-
268-AD.

Comments Due Date

    (a) We must receive comments by October 29, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A330-201, -202, -203, -223,
-243, -301, -321, -322, -323, -341, -342, and -343 airplanes; and
Model A340-200 and -300 series airplanes; all certified models, all
serial numbers; certificated in any category; except those on which
Airbus Modification 49144 (install rudder fly by wire) has been
embodied in production.

Subject

    (d) Fuselage.

Reason

    (e) The mandatory continuing airworthiness information (MCAI)
states:
    A review of the repair substantiations of the SRM (Structural
Repair Manual) has been done to take into account the latest
aircraft operational data (Aircraft Weight Variant and Fatigue
Flight Mission Profiles). As a result, all permanent fuselage skin
(Figure 202-210/213-214) and lap joint doubler (Figure 215-216)
repair principles published in the SRM chapter 53-00-11, Page Block
201 have been replaced with Oct/05 Revision by updated, simplified
and harmonized repair principles.
    These updates led to the de-validation of some repairs and to
reassess the repair inspection requirements. This situation if not
corrected, can affect the aircraft structural integrity with a
possible risk of decompression.
    In order to maintain the structural integrity, this
Airworthiness Directive (AD) renders mandatory the inspection of the
fuselage to identify possible permanent skin repairs and permanent
longitudinal lap joint repairs and to apply the associated
corrective actions.
    The corrective actions include contacting Airbus for repair/
inspection instructions, and repair, as applicable, for skin repairs
or longitudinal lap joint repairs that were done in accordance with
the repair principles in SRM chapter 53-00-11, Page Block 201,
before October 2005, or repairs that were done without using an
individual repair design approval sheet provided by Airbus.
