Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2010-0680; Directorate Identifier 2008-NM-195-AD; 
Amendment 39-16482; AD 2010-22-03]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A310 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:

    Analysis performed in the frame of the Extended Service Goal has 
led Airbus to modify the inspection programme [modification of 
thresholds, intervals and associated configurations] which is 
currently required by DGAC (Direction G[eacute]n[eacute]rale de 
l'Aviation Civile) France AD F-2005-001.
    This modified inspection programme is necessary to detect and 
prevent damage associated with a structural fatigue phenomenon of 
the rear spar internal angle and the tee fitting located in the 
centre wing box. This condition, if not corrected, could affect the 
structural integrity of the centre wing box.
* * * * *
    The unsafe condition is reduced structural integrity of the wings. 
We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective December 3, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 3, 
2010.

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 July 13, 2010 (75 FR 
39863), and proposed to supersede AD 2006-09-05, Amendment 39-14575 (71 
FR 25921, May 3, 2006). That NPRM proposed to correct an unsafe 
condition for the specified products. The MCAI states:

    Analysis performed in the frame of the Extended Service Goal has 
led Airbus to modify the inspection programme [modification of 
thresholds, intervals and associated configurations] which is 
currently required by DGAC (Direction G[eacute]n[eacute]rale de 
l'Aviation Civile) France AD F-2005-001 [which corresponds to FAA AD 
2006-09-05].
    This modified inspection programme is necessary to detect and 
prevent damage associated with a structural fatigue phenomenon of 
the rear spar internal angle and the tee fitting located in the 
centre wing box. This condition, if not corrected, could affect the 
structural integrity of the centre wing box.
    For the reason stated above, this new EASA AD retains the 
requirements of DGAC France AD F-2005-001, which is superseded, and 
refers to the latest revision of Airbus Service Bulletin (SB) A310-
57-2047.

    The unsafe condition is reduced structural integrity of the wings. 
This AD retains the requirements of AD 2006-09-05, but with certain 
reduced compliance times. The required actions include doing repetitive 
rotating probe inspections for any crack of the rear spar internal 
angle and the left and right sides of the tee fitting, and doing 
related investigative/corrective actions if necessary. The actions also 
include modifying the holes in the internal angle and tee fitting by 
cold expansion. 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.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

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

    Based on the service information, we estimate that this AD will 
affect about 66 products of U.S. registry.
    The actions that are required by AD 2006-09-05 and retained in this 
AD take up to 600 work-hours per product, at an average labor rate of 
$85 per work hour. Required parts cost up to $38,900 per product. Based 
on these figures, the estimated cost of the currently required actions 
is up to $89,900 per product.
    This new AD adds no new costs to affected operators; the 
manufacturer has modified the inspection program currently required by 
AD 2006-09-05. This AD reduces the compliance times required by the 
existing AD.

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.

2006-09-05].
    This modified inspection programme is necessary to detect and 
prevent damage associated with a structural fatigue phenomenon of 
the rear spar internal angle and the tee fitting located in the 
centre wing box. This condition, if not corrected, could affect the 
structural integrity of the centre wing box.
* * * * *
    The unsafe condition is reduced structural integrity of the 
wings.

New Requirements of This AD--Revised Compliance Times for Inspections 
Required by AD 2006-09-05

Initial and Repetitive Inspections of the Rear Spar Internal Angle

    (j) For airplanes on which an inspection of the rear spar 
internal angle has not been done in accordance with Airbus Service 
Bulletin A310-57-2047 as of the effective date of this AD: At the 
later of the times specified in paragraphs (j)(1) and (j)(2) of this 
AD, do a rotating probe inspection for any crack of the rear spar 
internal angle located in the center wing box and do all applicable 
related investigative and corrective actions, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A310-57-2047, 
Revision 08, dated July 2, 2009; except as required by paragraphs 
(n) and (o) of this AD. Do all applicable related investigative and 
corrective actions before further flight. Repeat the inspection 
thereafter at the applicable time specified in Table 4 of this AD. 
Certain compliance times are applicable to short range use, average 
flight time (AFT) equal to or less than 4 hours, or long range use, 
AFT exceeding 4 hours.

    Note 1: To establish the AFT, divide the accumulated flight time 
(counted from the take-off up to the landing) by the number of 
accumulated flight cycles. This gives the average flight time per 
flight cycle.

    (1) Within the applicable time specified in Table 3 of this AD.
    (2) Within the applicable time specified in paragraph (j)(2)(i), 
(j)(2)(ii), or (j)(2)(iii) of this AD:

    Although the MCAI or service information tells you to contact 
the manufacturer for repair information, paragraph (n) of this AD 
requires that you contact the FAA or EASA (or its delegated agent) 
instead.
    Although the MCAI or service information tells you to submit 
information to the manufacturer, paragraph (o) of this AD specifies 
that such submittal is not required.

Other FAA AD Provisions

    (s) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA,

Before using any approved AMOC on any airplane to which the AMOC 
applies, notify your principal maintenance inspector (PMI) or 
principal avionics inspector (PAI), as appropriate, or lacking a 
principal inspector, your local Flight Standards District Office. 
The AMOC approval letter must specifically reference this AD.
    (2) AMOCs approved previously in accordance with AD 2006-09-05, 
Amendment 39-14575, are approved as AMOCs for the corresponding 
provisions of this AD.
    (3) 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.
