14 CFR Part 39

[Docket No. FAA-2006-23690; Directorate Identifier 2004-NM-133-AD; 
Amendment 39-14684; AD 2006-15-04]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A300 B2 and B4 Series 
Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series 
Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called 
A300-600 Series Airplanes)

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding two existing airworthiness directives 
(AD) that apply to certain Airbus Model A300 B2, A300 B4, and A300-600 
series airplanes. One AD currently requires an inspection for cracks of 
the lower outboard flange of gantry No. 4 in the main landing gear 
(MLG) bay area, and repair if necessary. The other AD currently 
requires, among other actions, repetitive inspections of the gantry 
lower flanges, and repair if necessary. This new AD requires new 
repetitive inspections for cracks in the lower flange of certain 
gantries, and repair if necessary, which ends the existing inspection 
requirements. This new AD also provides for optional terminating 
actions for the new repetitive inspections. This AD results from a 
report of a large fatigue crack along the outboard flange of beam No. 4 
and a subsequent determination that existing inspections are 
inadequate. We are issuing this AD to detect and correct fatigue cracks 
in the lower flanges of gantries 1 through 5 inclusive in the MLG bay 
area, which could result in reduced structural integrity of the 
fuselage, and consequent rapid decompression of the airplane.

DATES: This AD becomes effective August 24, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of Airbus Service Bulletin A300-53-0379, Revision 01, 
excluding Appendix 01, dated October 4, 2005; and Airbus Service 
Bulletin A300-53-6152, Revision 01, excluding Appendix 01, dated 
October 4, 2005; listed in the AD as of August 24, 2006.
    On October 19, 2004 (69 FR 55329, September 14, 2004), the Director 
of the Federal Register approved the incorporation by reference of 
Airbus Service Bulletin A300-53-6128, excluding Appendix 01, dated 
March 5, 2001.
    On January 22, 2004 (69 FR 867, January 7, 2004), the Director of 
the Federal Register approved the incorporation by reference of Airbus 
All Operators Telex A300-53A0371, Revision 01, dated September 10, 
2003; and Airbus All Operators Telex A300-53A6145, Revision 01, dated 
September 10, 2003.
    On July 30, 1998 (63 FR 34589, June 25, 1998), the Director of the 
Federal Register approved the incorporation by reference of Airbus All 
Operators Telex (AOT) 53-11, dated October 13, 1997.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at http://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Management Facility office 
(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

Discussion

    The FAA issued a supplemental notice of proposed rulemaking (NPRM) 
to amend 14 CFR part 39 to include an AD that supersedes AD 2003-26-10, 
amendment 39-13408 (69 FR 867, January 7, 2004), and AD 2004-18-13, 
amendment 39-13792 (69 FR 55329, dated September 14, 2004). The 
existing ADs apply to certain Airbus Model A300 B2 and A300 B4 series 
airplanes, and Model A300 B4-600, B4-600R, and F4-600R series 
airplanes, and Model C4-605R Variant F airplanes (collectively called 
A300-600 series airplanes). That supplemental NPRM was published in the 
Federal Register on May 17, 2006 (71 FR 28615). That supplemental NPRM 
proposed to continue to require an inspection for cracks of the lower 
outboard flange of gantry No. 4 in the main landing gear (MLG) bay 
area, and repair if necessary. That supplemental NPRM also proposed to 
continue to require repetitive inspections of the gantry lower flanges, 
and repair if necessary. In addition, that supplemental NPRM proposed 
to require new repetitive inspections for cracks in the lower flange of 
certain gantries, and repair if necessary, which ends the existing 
inspection requirements. That supplemental NPRM also proposed optional 
terminating actions for the new repetitive inspections. That 
supplemental also revised the original NPRM by including additional 
airplanes that were excluded from the applicability.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment that has been 
received on the supplemental NPRM.

Request To Refer to Latest Service Bulletin

    Airbus states that it has issued Service Bulletins A300-53-0360, 
Revision 01, dated May 31, 2006; and A300-53-6132, Revision 01, dated 
June 7, 2006; whose original issues are listed in paragraph (m)(2) of 
the supplemental NPRM.
    We infer that Airbus is requesting that Revision 01 of Service 
Bulletins A300-53-0360 and A300-53-6132 be referred to in paragraph 
(m)(2) of the AD. We agree. We have reviewed Revision 01 of both 
service bulletins. Revision 01 of both service bulletins revises three 
illustrations. The reinforcement procedures in Revision 01 of both 
service bulletins are identical to that in the original issues of the 
service bulletins. No additional work is required for airplanes 
modified in accordance with the original issues of the service 
bulletins. Therefore, we have revised paragraph (m)(2) of this AD to 
refer to Revision 01 of both service bulletins and added a new 
paragraph (p) to the AD (subsequent paragraphs have been redesignated) 
to give credit for accomplishing the original issues of both service 
bulletins.

Explanation of Change Made to the Supplemental NPRM

    Paragraphs (g), (i)(4), and (n) of the supplemental NPRM specify 
making repairs using a method approved by either the FAA or the 
Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC) (or its 
delegated agent). The European

[[Page 41110]]

Aviation Safety Agency (EASA) has assumed responsibility for the 
airplane modes that would be subject to this AD. Therefore, we have 
revised those paragraphs of this AD to specify making repairs using a 
method approved by either the FAA, the DGAC (or its delegated agent), 
or the EASA (or its delegated agent).

Conclusion

    We have carefully reviewed the available data, including the 
comment that has been received, and determined that air safety and the 
public interest require adopting the AD with the changes described 
previously. We have determined that these changes will neither increase 
the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    This AD will affect about 165 airplanes of U.S. registry. The 
following table provides the estimated costs for U.S. operators to 
comply with this AD. Not all actions must be completed on all 
airplanes.

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 have 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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

[[Page 41111]]

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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
