Airworthiness Directives; Airbus Model A330-200 and -300 Series 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

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

SUMMARY: We are revising an earlier NPRM for the products listed above. 
This action revises the earlier NPRM by expanding the scope. 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:
* * * * *
    The airworthiness limitations applicable to the Certification 
Maintenance Requirements

[[Page 6579]]

(CMR) are given in Airbus A330 ALS Part 3, which is approved by the 
European Aviation Safety Agency (EASA).
    The revision 03 of Airbus A330 ALS Part 3 introduces more 
restrictive maintenance requirements and/or airworthiness 
limitations. Failure to comply with this revision constitutes an 
unsafe condition.
* * * * *
    The unsafe condition is safety-significant latent failures that 
would, in combination with one or more other specific failures or 
events, result in a hazardous or catastrophic failure condition. The 
proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

Discussion

    We issued a supplemental notice of proposed rulemaking (NPRM) to 
amend 14 CFR part 39 to include an airworthiness directive (AD) that 
would apply to certain Model A330-200 and -300 series airplanes. That 
supplemental NPRM was published in the Federal Register on August 4, 
2010 (75 FR 46861). The original NPRM (75 FR 4710, January 29, 2010) 
proposed to require actions intended to address the unsafe condition 
for the products listed above. The supplemental NPRM introduced new or 
more restrictive maintenance requirements and/or airworthiness 
limitations as specified in Airbus A330 ALS, Part 3--Certification 
Maintenance Requirements, Revision 02, dated December 16, 2009.
    Since that supplemental NPRM was issued, we have received Airbus 
A330 ALS, Part 3--Certification Maintenance Requirements, Revision 03, 
dated July 29, 2010, which contains new and more restrictive 
requirements. We referred to Airbus A330 ALS, Part 3--Certification 
Maintenance Requirements, Revision 02, dated December 16, 2009, as the 
appropriate source of service information in the original NPRM. We have 
revised this second supplemental NPRM to refer to Airbus A330 ALS, Part 
3--Certification Maintenance Requirements, Revision 03, dated July 29, 
2010. The European Aviation Safety Agency (EASA) has issued EASA AD 
2010-0264, dated December 20, 2010. You may obtain further information 
by examining the MCAI in the AD docket.

Comments

    We have considered the following comment received on the first 
supplemental NPRM.

Request To Revise Paragraphs (f) and (g) of the First Supplemental NPRM

    Airbus requested that we revise paragraphs (f) and (g) of the first 
supplemental NPRM. Airbus stated that Section 25.1529 of the Federal 
Aviation Regulations (14 CFR 25.1529) and Appendix H of 14 CFR part 25 
require the airplane type certificate holder--not the operator--to 
produce and update the Instructions for Continued Airworthiness (ICA). 
Airbus stated that the type certificate holder must make the ICAs 
available to all operators and owners, who are then responsible to 
incorporate the latest applicable contents of revisions of the 
Airworthiness Limitations section (ALS) or any other part of the ICA 
into the approved maintenance program. Airbus stated that operators and 
owners demonstrate compliance with Section 121.367 of the Federal 
Aviation Regulations (14 CFR 121.367) and Section 121.369 of the 
Federal Aviation Regulations (14 CFR 121.369) by following this 
procedure.
    We agree that the ALI requirement could be stated more clearly so 
that it does not directly require operators to revise the ALS of the 
ICA. It is more appropriate to require revising the operators' 
maintenance programs. However, we have not revised paragraph (f) of 
this second supplemental NPRM because it is a restatement of the 
existing AD. We have revised paragraph (g) of this second supplemental 
NPRM to clarify that that the operators and owners are required to 
incorporate the latest applicable contents of revisions of the ALS into 
the maintenance program.

Change to Applicability

    We have also added Airbus Model A330-223F and A330-243F airplanes 
to the applicability of this supplemental NPRM. There are no Model 
A330-223F and A330-243F airplanes on the U.S. registry.

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

[[Page 6580]]

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.
    Certain changes described above expand the scope of the earlier 
NPRM. As a result, we have determined that it is necessary to reopen 
the comment period to provide additional opportunity for the public to 
comment on this proposed 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 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 55 products of U.S. registry.
    The actions that are required by AD 2007-05-08 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 $4,675, 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); 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, 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 39-14969 (72 FR 
9658, March 5, 2007) and adding the following new AD:

Airbus: Docket No. FAA-2009-1212; Directorate Identifier 2008-NM-
167-AD.

Comments Due Date

    (a) We must receive comments by March 4, 2011.

Affected ADs

    (b) This AD supersedes AD 2007-05-08, Amendment 39-14969.

Applicability

    (c) This AD applies to all Airbus Model A330-201, -202, -203, -
223, -223F, -243, -243F, -301, -302, -303, -321, -322, -323, -341, -
342, and -343 airplanes, certificated in any category; all serial 
numbers.

Subject

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

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
* * * * *
    The airworthiness limitations applicable to the Certification 
Maintenance Requirements (CMR) are given in Airbus A330 ALS Part 3, 
which is approved by the European Aviation Safety Agency (EASA).
    The revision 03 of Airbus A330 ALS Part 3 introduces more 
restrictive maintenance requirements and/or airworthiness 
limitations. Failure to comply with this revision constitutes an 
unsafe condition.
* * * * *
    The unsafe condition is safety-significant latent failures that 
would, in combination with one or more other specific failures or 
events, result in a hazardous or catastrophic failure condition.

    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 (k) 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) 25-1529-1A.

Restatement of Requirements of AD 2007-05-08, With Requirements for 
Model A340 Airplanes Removed

Revise the Airworthiness Limitations Section of the Instructions 
for Continued Airworthiness

    (f) Unless already done: Within 90 days after April 9, 2007 (the 
effective date of AD 2007-05-08), revise the Airworthiness 
Limitations section of the Instructions for Continued Airworthiness 
by incorporating Airbus A330 Certification Maintenance Requirements, 
Document 955.2074/93, Issue 19, dated March 22, 2006. Accomplish the 
actions specified in the applicable CMR at the times specified in 
the applicable CMR and in accordance with the applicable CMR, except 
as provided by paragraphs (f)(1) and (f)(2) of this AD.

[[Page 6581]]

    (1) The associated interval for any new task is to be counted 
from April 9, 2007.
    (2) The associated interval for any revised task is to be 
counted from the previous performance of the task.
