AGENCY: Federal Aviation Administration, Department of Transportation.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing 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:

    Following the occurrence of cracks on the MLG [main landing 
gear] rib 5 RH [right-hand] and LH [left-hand] attachment fitting 
lower flanges, DGAC [Direction G[eacute]n[eacute]rale de l'Aviation 
Civile] France AD 2003-318(B) [parallel to part of FAA AD 2006-12-
13] was issued to require repetitive inspections and, as terminating 
action * * *[.]
    Subsequently, new cases of cracks were discovered during 
scheduled maintenance checks by operators of A300B4 and A300-600 
type aeroplanes on which the terminating action * * * [was] 
embodied. This condition, if not corrected, could affect the 
structural integrity of those aeroplanes.
* * * * *

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective January 5, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 5, 
2011.
    On July 18, 2006 (71 FR 33994, June 13, 2006), the Director of the 
Federal Register approved the incorporation by reference of certain 
other publications listed in this AD.
    On April 12, 2000 (65 FR 12077, March 8, 2000), the Director of the 
Federal Register approved the incorporation by reference of certain 
other publications listed in this AD.

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 November 18, 2009 
(74 FR 59483), and proposed to supersede AD 2006-12-13, Amendment 39-
14639 (71 FR 33994, June 13, 2006). That NPRM proposed to correct an 
unsafe condition for the specified products. The MCAI states:

    Following the occurrence of cracks on the MLG [main landing 
gear] rib 5 RH [right-hand] and LH [left-hand] attachment fitting 
lower flanges, DGAC [Direction G[eacute]n[eacute]rale de l'Aviation 
Civile] France AD 2003-318(B) [parallel to part of FAA AD 2006-12-
13] was issued to require repetitive inspections and, as terminating 
action, the embodiment of Airbus Service Bulletins (SB) A300-57-0235 
and A300-57-6088 * * *.
    Subsequently, new cases of cracks were discovered during 
scheduled maintenance checks by operators of A300B4 and A300-600 
type aeroplanes on which the terminating action SB's were embodied. 
This condition, if not corrected, could affect the structural 
integrity of those aeroplanes.
    To address and correct this condition, Airbus developed an 
inspection programme for aeroplanes modified in accordance with SB 
A300-57-0235 or A300-57-6088. This inspection programme was required 
to be implemented by DGAC France AD F-2005-113, original issue and 
later revision 1 [parallel to part of FAA AD 2006-12-13].
    A new EASA [European Aviation Safety Agency] AD 2008-0111, 
superseding DGAC France AD F-2005-113R1, was issued to reduce the 
applicability. For aeroplanes already compliant with DGAC France AD 
F-2005-113R1, no further action was required.
    Since EASA AD 2008-0111 issuance, Airbus reviewed the inspection 
programmes of SB A300-57A0246 and SB A300-57A6101 to introduce 
repetitive inspections including a new inspection technique for 
holes 47 and 54 and to reduce inspections threshold and intervals 
from 700 Flight Cycles (FC) to 400 FC until a revised terminating 
action is made available.
    For the reasons stated above, AD 2009-0081 superseded EASA AD 
2008-0111 and required operators to comply with the new inspection 
programme introduced in

[[Page 74611]]

Revisions 3 of Airbus SB A300-57A0246 and Airbus SB A300-57A6101.
    This AD is revised to introduce an optional terminating action 
which consists of spot-facing the sensitive holes of the MLG Rib 5 
(LH and RH) bottom flanges.

Required actions include contacting Airbus for repair instructions, if 
necessary, and doing the repair. 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 considered the comment received.

Request To Revise Proposed Costs of Compliance

    FedEx Express commented that the NPRM would affect 57 of its 
airplanes. FedEx Express states that the inspections do not require any 
special inspection techniques, training, or tooling, and that it has 
scheduled the proposed inspections although it has not yet inspected 
any airplanes. FedEx Express also states that the inspection interval 
is sufficient, but if cracks are found, significant downtime will be 
required.
    From these comments, we infer that FedEx Express is requesting that 
we revise the Costs of Compliance section of the NPRM. We do not agree 
with the request. We recognize that, in accomplishing the requirements 
of any AD, operators might incur ``incidental'' costs in addition to 
the ``direct'' costs that are reflected in the cost analysis presented 
in the AD preamble. However, the cost analysis in AD rulemaking actions 
typically does not include incidental costs. We have, however, reviewed 
the figures that we have used over the past several years to calculate 
costs to operators. To account for various inflationary costs in the 
airline industry, we find it necessary to increase the labor rate used 
in these calculations from $80 per work hour to $85 per work hour. The 
cost impact information, below, reflects this increase in the specified 
hourly rate. We have also corrected the calculations used in 
determining the cost to operators.

Explanation of Change to the NPRM

    Paragraph (p)(5) of the NPRM specifies contacting Airbus for a 
repair solution and doing the repair. The European Aviation Safety 
Agency (EASA) has assumed responsibility for the airplane models 
subject to this AD. Therefore, we have revised paragraph (p)(5) of this 
AD to add a provision for making repairs using a method approved by 
either the Manager of the International Branch, ANM-116, Transport 
Airplane Directorate, FAA or the EASA (or its delegated agent).

Explanation of Change to AD

    We have revised paragraphs (j) and (k) of this AD; and Tables 1, 2, 
3, 4, and 5 of this AD to remove Airbus Model A300 B2-1A, F4-622R, and 
C4-605R Variant F airplanes. We have determined that these airplanes 
were inadvertently carried over from the paragraph callouts of the 
previous AD into the NPRM. These airplanes are not subject to the 
identified unsafe condition and therefore are not affected by this AD.

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 also 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 will affect about 155 products of U.S. 
registry.
    The actions that are required by AD 2006-12-13 and retained in this 
AD take about 76 work-hours per product, at an average labor rate of 
$85 per work hour. Required parts cost about $10,270 per product. Based 
on these figures, the estimated cost of the currently required actions 
is $16,730 per product.
    We estimate that it will take about 3 work-hours per product to 
comply with the new basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD to the U.S. operators to be $39,525 or $255 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.

Subject

    (d) Air Transport Association (ATA) of America Code 57: Wings.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Following the occurrence of cracks on the MLG [main landing 
gear] rib 5 RH [right-hand] and LH [left-hand] attachment fitting 
lower flanges, DGAC [Direction G[eacute]n[eacute]rale de l'Aviation 
Civile] France AD 2003-318(B) [parallel to part of FAA AD 2006-12-
13] was issued to require repetitive inspections and, as terminating 
action, the embodiment of Airbus Service Bulletins (SB) A300-57-0235 
and A300-57-6088 * * *.
    Subsequently, new cases of cracks were discovered during 
scheduled maintenance checks by operators of A300B4 and A300-600 
type aeroplanes on which the terminating action SB's were embodied. 
This condition, if not corrected, could affect the structural 
integrity of those aeroplanes.
    To address and correct this condition, Airbus developed an 
inspection programme for aeroplanes modified in accordance with SB 
A300-57-0235 or A300-57-6088. This inspection programme was required 
to be implemented by DGAC France AD F-2005-113, original issue and 
later revision 1 [parallel to part of FAA AD 2006-12-13].
    A new EASA [European Aviation Safety Agency] AD 2008-0111, 
superseding DGAC France AD F-2005-113R1, was issued to reduce the 
applicability. For aeroplanes already compliant with DGAC France AD 
F-2005-113R1, no further action was required.
    Since EASA AD 2008-0111 issuance, Airbus reviewed the inspection 
programmes of SB A300-57A0246 and SB A300-57A6101 to introduce 
repetitive inspections including a new inspection technique for 
holes 47 and 54 and to reduce inspections threshold and intervals 
from 700 Flight Cycles (FC) to 400 FC until a revised terminating 
action is made available.
    For the reasons stated above, AD 2009-0081 superseded EASA AD 
2008-0111 and required operators to comply with the new inspection 
programme introduced in Revisions 3 of Airbus SB A300-57A0246 and 
Airbus SB A300-57A6101.
    This AD is revised to introduce an optional terminating action 
which consists of spot-facing the sensitive holes of the MLG Rib 5 
(LH and RH) bottom flanges.
Required actions include contacting Airbus for repair instructions, 
if necessary, and doing the repair.

Restatement of Requirements of AD 2000-05-07

    (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.

Repetitive Inspections

    (g) Perform a detailed inspection and a high-frequency eddy 
current (HFEC) inspection to detect cracks in Gear Rib 5 of the main 
landing gear (MLG) attachment fittings at the lower flange, in 
accordance with the Accomplishment Instructions of any applicable 
service bulletin listed in Table 1 and Table 2 of this AD, at the 
time specified in paragraph (g)(1) or (g)(2) of this AD. After April 
12, 2000 (the effective date of AD 2000-05-07, Amendment 39-11616), 
only the service bulletins listed in Table 2 of this AD may be used. 
Repeat the inspections thereafter at intervals not to exceed 1,500 
flight cycles, until the actions specified in paragraph (i), (j), or 
(l) of this AD are accomplished.

     (1) For airplanes that have accumulated 20,000 or more total 
flight cycles as of March 9, 1998 (the effective date of AD 98-03-
06, Amendment 39-10298): Inspect within 500 flight cycles after 
March 9, 1998.
    (2) For airplanes that have accumulated less than 20,000 total 
flight cycles as of March 9, 1998: Inspect prior to the accumulation 
of 18,000 total flight cycles, or within 1,500 flight cycles after 
March 9, 1998, whichever occurs later.

    Note 1: For the purposes of this AD, a detailed inspection is 
defined as: ``An intensive visual examination of a specific 
structural area, system, installation, or assembly to detect damage, 
failure, or irregularity. Available lighting is normally 
supplemented with a direct source of good lighting at intensity 
deemed appropriate by the inspector. Inspection aids such as mirror, 
magnifying lenses, etc., may be used. Surface cleaning and elaborate 
access procedures may be required.''


    Note 2: Accomplishment of the initial detailed and HFEC 
inspections prior to April 12, 2000, in accordance with Airbus 
Service Bulletin A300-57A0234 or A300-57A6087, both dated August 5, 
1997, as applicable, is considered acceptable for compliance with 
the initial inspections required by paragraph (g) of this AD.

Repair for Any Crack Found During Inspections Required by Paragraph (g) 
of This AD

    (h) If any crack is detected during any inspection required by 
paragraph (g) of this AD, prior to further flight, accomplish the 
requirements of paragraph (h)(1) or (h)(2) of this AD, as 
applicable.
    (1) If a crack is detected at one hole only, and the crack does 
not extend out of the spotface of the hole, repair in accordance 
with the Accomplishment Instructions of the applicable service 
bulletin in Table 2 of this AD.
    (2) If a crack is detected at more than one hole, or if any 
crack at any hole extends out of the spotface of the hole, repair in 
accordance with a method approved by the Manager, International 
Branch, ANM-116, Transport Airplane Directorate, FAA, or the 
European Aviation Safety Agency (EASA) (or its delegated agent).

Terminating Modification for Repetitive Inspections Required by 
Paragraphs (g) and (j) of This AD

    (i) Except as required by paragraph (l) of this AD, prior to the 
accumulation of 21,000 total flight cycles, or within 2 years after 
October 20, 1999 (the effective date of AD 99-19-26, amendment 39-
11313), whichever occurs later: Modify Gear Rib 5 of the MLG 
attachment fittings at the lower flange in accordance with the 
Accomplishment Instructions of the applicable service bulletin in 
Table 3 of this AD. After July 18, 2006 (the effective date of AD 
2006-12-13), only Revision 04 of Airbus Service Bulletin A300-57-
6088, and Revisions 04 and 05 of Airbus Service Bulletin A300-57-
0235 may be used. Accomplishment of this modification constitutes
