Airworthiness Directives; Airbus Model A330-200 and -300 Series 
Airplanes, and A340-200, -300, -500, and -600 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for 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:

    Several cases of corrosion and damage on the Down Drive Shafts 
(DDS), between the Down Drive Gear Box (DDGB) and the Input Gear Box 
(IPGB), on all 10 Flap Tracks (5 per wing), have been reported by 
AIRBUS Long Range Operators.
    Investigations have revealed that corrosion and wear due to 
absence of grease in the spline interfaces could cause [DDS] 
disconnection which could result in a free movable flap surface, 
potentially leading to aircraft asymmetry or even flap detachment.
* * * * *
    The unsafe condition could reduce the ability of the flightcrew to 
maintain the safe flight and landing 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 26, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 26, 
2010.

ADDRESSES: You may examine the AD docket on the Internet at http://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 supplemental notice of proposed rulemaking (NPRM) to 
amend 14 CFR part 39 to include an AD that would apply to the specified 
products. That supplemental NPRM was published in the Federal Register 
on March 29, 2010 (75 FR 15353). That supplemental NPRM proposed to 
correct an unsafe condition for the products listed above.

Explanation of Revised Service Information

    Airbus has issued Mandatory Service Bulletin A330-27-3152, Revision 
03, including Appendices 1 and 2, dated February 22, 2010. Airbus 
Mandatory Service Bulletin A330-27-3152, Revision 02, dated September 
23, 2008, is referred to as the appropriate source of service 
information for accomplishing certain actions in the supplemental NPRM. 
The changes in Airbus Mandatory Service Bulletin A330-27-

[[Page 42590]]

3152, Revision 03, dated February 22, 2010, are minor and no additional 
work is necessary for airplanes on which the actions specified in 
Revision 02 of this service bulletin were done.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

Comments

    Delta supports the proposed actions in the supplemental NPRM and 
asks that we include Airbus Mandatory Service Bulletin A330-27-3152, 
Revision 03, dated February 22, 2010, as the appropriate source of 
service information for accomplishing certain actions. Delta also asks 
that we give credit for Airbus Mandatory Service Bulletin A330-27-3152, 
Revision 02, dated September 23, 2008.
    As stated previously, Airbus issued Mandatory Service Bulletin 
A330-27-3152, Revision 03, dated February 22, 2010. We have cited 
Airbus Mandatory Service Bulletin A330-27-3152, Revision 03, dated 
February 22, 2010, as the appropriate source of service information for 
accomplishing the required actions and have changed the service 
bulletin references in Tables 1 and 2 of this AD accordingly.

Conclusion

    We reviewed the available data, including the comment received, 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 affects about 41 products of U.S. 
registry. We also estimate that it takes 65 work-hours per product to 
comply with the 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 $226,525, or $5,525 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 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 http://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.

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

2010-15-02 Airbus: Amendment 39-16368. Docket No. FAA-2009-0003; 
Directorate Identifier 2007-NM-251-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective August 
26, 2010.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A330-201, -202, -203, -223, 
-243, -301, -302, -303, -321, -322, -323, -341, -342, and -343 
series airplanes, A340-211, -212, -213, -311, -312, and -313 series 
airplanes, and A340-541 and -642 airplanes, certificated in any 
category; all certified models, all manufacturer serial numbers.

Subject

    (d) Air Transport Association (ATA) of America Code 27: Flight 
Controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Several cases of corrosion and damage on the Down Drive Shafts 
(DDS), between the Down Drive Gear Box (DDGB) and the Input Gear Box 
(IPGB), on all 10 Flap Tracks (5 per wing), have been reported by 
AIRBUS Long Range Operators.
    Investigations have revealed that corrosion and wear due to 
absence of grease in the spline interfaces could cause [DDS] 
disconnection which could result in a free movable flap surface, 
potentially leading to aircraft asymmetry or even flap detachment.
    Emergency Airworthiness Directive (EAD) 2007-0222-E mandated on 
all aircraft older than 6 years since AIRBUS original delivery date 
of the aircraft, an initial inspection of all DDS and IPGB for 
corrosion and wear detection in order to replace any damaged part.
    Revision 1 of EAD 2007-0222-E aimed for clarifying the 
compliance instructions.

[[Page 42591]]

    [EASA AD 2008-0026] supersedes the EAD 2007-0222R1-E and 
mandates repetitive inspections every 6 years for all the fleet.

The unsafe condition could reduce the ability of the flightcrew to 
maintain the safe flight and landing of the airplane. The corrective 
actions include replacing damaged parts.

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.

Actions

    (g) Do the applicable inspections and corrective actions 
specified in paragraphs (g)(1) and (g)(2) of this AD, in accordance 
with the instructions of the applicable service information 
specified in Table 1 of this AD.
