14 CFR Part 39

[Docket No. FAA-2011-1066; Directorate Identifier 2011-NM-050-AD; 
Amendment 39-16917; AD 2012-01-05]

Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for certain Airbus Model A300 B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and 
B4-203 airplanes; and Model A300 B4-601, B4-603, B4-620, B4-622, B4-
605R, B4-622R, and F4-605R airplanes. That AD currently requires 
repetitive inspections for cracking in Gear Rib 5 of the main landing 
gear (MLG) attachment fittings at the lower flange, and repair if 
necessary; and provides an optional spot-facing modification around 
certain fastener holes, which would terminate certain repetitive 
inspections. This new AD mandates the optional spot-facing 
modification. This AD was prompted by new cases of cracks discovered 
during scheduled maintenance checks. We are issuing this AD to prevent 
cracking of the Gear Rib 5 right-hand and left-hand attachment fitting 
at the lower flanges of the MLG, which could result in failed bolts 
penetrating through the rear spar and into a fuel tank, consequent fuel 
loss, and reduced structural integrity of the airplane.

DATES: This AD becomes effective June 12, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 12, 
2012.
    The Director of the Federal Register approved the incorporation by

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 October 11, 2011 (76 
FR 62673), and proposed to supersede AD 2010-23-26, Amendment 39-16516 
(75 FR 74610, December 1, 2010). 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) 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, Amendment 
39-14639 (71 FR 33994, June 13, 2006)].
    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, EASA 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.
    EASA AD 2009-0081 R1 [which corresponds to FAA AD 2010-23-26, 
Amendment 39-16516 (75 FR 74610, December 1, 2010)] has been 
published to introduce an optional terminating action which 
consisted of spot-facing the sensitive holes of the MLG Rib 5 (LH 
and RH) bottom flanges.
    Later discussions with Airbus have demonstrated the necessity to 
require the spot-facing modification as a final solution (no longer 
optional). This new [EASA] AD retains the inspection requirements of 
EASA AD 2009-0081 R1, which is superseded, and requires the spot-
facing of sensitive holes of the MLG Rib 5 (LH and RH) bottom 
flanges as terminating action.

Required actions include repairing discrepancies (e.g., cracking or a 
second oversize or greater fastener hole). 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. The

[[Page 26938]]

commenter supports the NPRM (76 FR 62673, October 11, 2011).

Explanation of Changes Made to This AD

    We have made the following changes to this AD. These changes have 
not changed the intent of any provisions specified in this AD.
     Revised certain headers throughout this AD.
     Redesignated Notes 1, 2, and 3 of the NPRM (76 FR 62673, 
October 11, 2011) as paragraphs (g)(3), (q)(1), and (q)(2) of this AD, 
respectively.
     Redesignated paragraph (n) of the NPRM (76 FR 62673, 
October 11, 2011) as paragraph (q)(3) of this AD, and redesignated 
subsequent paragraphs accordingly.
     We have revised paragraphs (g), (i), (o)(1), (o)(3), 
(o)(4), and (o)(5) of this AD to clarify the specific actions for which 
the specified service information is required.
     We have revised the headings of Tables 1, 2, 3, 4, 5, and 
6 of this AD to clarify the purpose of the content in those tables.
     We have revised the wording in paragraphs (q)(1), (q)(2), 
(q)(3), and (q)(4) of this AD (Notes 2 and 3 and paragraphs (n) and (r) 
of the NPRM (76 FR 62673, October 11, 2011), respectively); this change 
has not changed the intent of these paragraphs.

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--and minor editorial changes. 
We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (76 FR 62673, October 11, 2011) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 62673, October 11, 2011).

Costs of Compliance

    We estimate that this AD will affect about 155 products of U.S. 
registry.
    The actions that are required by AD 2010-23-26, Amendment 39-16516 
(75 FR 74610, December 1, 2010), and retained in this AD take about 79 
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 $16,985 per 
product.
    We estimate that it will take about 100 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 the AD on U.S. operators to be $1,317,500, or $8,500 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 (76 FR 62673, October 11, 
2011), the regulatory evaluation, any comments received, and other
