Airworthiness Directives; Airbus Model A300 B2-1C, A300 B2-203, 
A300 B2K-3C, A300-B4-103, A300 B4-203, and A300 B4-2C Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
that applies to 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:

* * * [C]racks * * * in sections 13 to 18 of the fuselage between 
rivets of longitudinal lap joints between frames 18 and 80 which 
could affect the structural integrity of the fuselage if not 
corrected.
* * * * *
    We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective November 16, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 16, 
2011.

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 May 10, 2011 (76 FR 
26962), and proposed to supersede AD 90-01-10, Amendment 39-6448 (55 FR 
261, January 4, 1990). That NPRM proposed to correct an unsafe 
condition for the specified products. The MCAI states:

    This Airworthiness Directive (AD) is issued in order to prevent 
cracks development in sections 13 to 18 of the fuselage between 
rivets of longitudinal lap joints between frames 18 and 80 which 
could affect the structural integrity of the fuselage if not 
corrected.
    This new AD:

--Retains the requirements of DGAC AD 1989-061-092(B)R4 [which 
corresponds to FAA AD 90-01-10 (55 FR 261, January 4, 1990)], which 
is cancelled;
--Takes into account a new inspection program as detailed in AIRBUS 
Service Bulletins (SB) A300-53-0211 Revision 7, which will allow 
A300 aircraft to reach the Limit of Validity (LOV).

    This AD has been republished to correctly refer to SB A300-53-
0211 in Note 2 of the Compliance section.

    The inspection program consists of repetitive detailed inspections 
for disbonding and cracking of the fuselage inner doubler; eddy current 
and ultrasonic inspections of the fuselage longitudinal lap joints for 
cracking; and repair if necessary (i.e., repairing any cracking or 
disbonding, or contacting Airbus for repair instructions 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 received no comments on the NPRM (76 FR 26962, May 10, 
2011) or on the determination of the cost to the public.

Clarification of Service Bulletin References

    Paragraphs (h)(1) and (j)(1) of the NPRM (76 FR 26962, May 10, 
2011) refer to Airbus Mandatory Service Bulletin A300-53-0211 as the 
service information for airplanes on which an inspection of the 
longitudinal lap joints has been done. For clarity, we have revised the 
paragraphs to refer to the latest service bulletin revision and, 
therefore, we have revised paragraphs (h)(1) and (j)(1) of this AD to 
refer to Airbus Mandatory Service Bulletin A300-53-0211, Revision 07, 
dated December 1, 2006.
    Paragraphs (l)(1), (1)(2), (m)(1), (m)(2), (n)(1), (n)(2), (o)(1), 
and (o)(2) of the NPRM (76 FR 26962, May 10, 2011) refer to Airbus 
Service Bulletin A300-53-229 for the definition of ``major'' and 
``minor'' disbonding. For clarity, we have revised the paragraphs to 
refer to the latest service bulletin revision and, therefore, we have 
revised paragraphs (l)(1), (1)(2), (m)(1), (m)(2), (n)(1), (n)(2), 
(o)(1), and (o)(2) of this AD to refer to Airbus Service Bulletin A300-
53-229, Revision 5, dated April 8, 1997.

Conclusion

    We reviewed the available data 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.

[[Page 63178]]

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 5 products of U.S. 
registry.
    We estimate that it will take about 3,735 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 $1,587,375, or $317,475 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 26962, May 10, 2011), 
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.

inclusive.

Subject

    (d) Air Transport Association (ATA) of America Code 53: 
Fuselage.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    This Airworthiness Directive (AD) is issued in order to prevent 
cracks development in sections 13 to 18 of the fuselage between 
rivets of longitudinal lap joints between frames 18 and 80 which 
could affect the structural integrity of the fuselage if not 
corrected.
    This new AD:

--Retains the requirements of DGAC AD 1989-061-092(B)R4 [which 
corresponds to FAA AD 90-10-10 (55 FR 261, January 4, 1990)], which 
is cancelled;
--Takes into account a new inspection program as detailed in AIRBUS 
Service Bulletins (SB) A300-53-0211 Revision 7, which will allow 
A300 aircraft to reach the Limit of Validity (LOV).

    This AD has been republished to correctly refer to SB A300-53-
0211 in Note 2 of the Compliance section.
    The inspection program consists of repetitive detailed 
inspections for disbonding and cracking of the fuselage inner 
doubler; eddy current and ultrasonic inspections of the fuselage 
longitudinal lap joints for cracking; and repair if necessary (i.e., 
repairing any cracking or disbonding, or contacting Airbus for 
repair instructions and doing the repair).

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.

Repetitive Inspections of ``Special Areas'' and Repair or Modification 
if Necessary

    (g) For airplanes on which an eddy current inspection of the 
``special'' areas of the longitudinal lap joints has not been done 
as of the effective date of this AD in accordance with Airbus 
Mandatory Service Bulletin A300-53-0211: Prior to the accumulation 
of 24,000 total flight cycles, or within 2,000 flight cycles after 
the effective date of this AD, whichever occurs later; do an eddy 
current inspection for cracking of the ``special'' areas of the 
longitudinal lap joints, in accordance with the Accomplishment 
Instructions of Airbus Mandatory Service Bulletin A300-53-0211, 
Revision 07, dated December 1, 2006. If no cracking is found, repeat 
the inspection thereafter at the applicable intervals specified in 
Table 1 of this AD. If any crack is found during any inspection 
required by this paragraph, repair or modify before further flight, 
in accordance with the Accomplishment Instructions of Airbus 
Mandatory Service Bulletin A300-53-0211, Revision 07, dated December 
1, 2006; and do the applicable inspection of the repaired or 
modified area in accordance with paragraph (k) of this AD. 
``Special'' areas of the longitudinal lap joints are defined in 
Airbus Mandatory Service Bulletin A300-53-0211, Revision 07, dated 
December 1, 2006.

in Airbus Service Bulletin A300-53-229, Revision 5, dated April 8, 
1997, is found: Within 1,000 flight cycles after doing the 
inspection, repair, in accordance with the Accomplishment 
Instructions of Airbus Service Bulletin A300-53-229, Revision 5, 
dated April 8, 1997.
    (3) If any cracking is found, repair prior to further flight, in 
accordance with Airbus Service Bulletin A300-53-229, Revision 5, 
dated April 8, 1997.
    (o) For airplanes on which any inspections of the fuselage 
bonded inner doublers of the longitudinal lap joints in Sections 16 
and 17 at Stringer 31 left-hand and right-hand for disbonding and 
cracking have been done as of the effective date of this AD in 
accordance with Airbus Service Bulletin A300-53-229; except 
airplanes on which a repair of that area has been done in accordance 
with Airbus Service Bulletin A300-53-229: Within 7 years or 12,000 
flight cycles after doing the inspection, whichever occurs first; or 
within 60 days after the effective date of this AD; whichever occurs 
later, do a detailed inspection of the fuselage bonded inner doubles 
of the longitudinal lap joints in Sections 16 and 17 at Stringer 31 
left-hand and right-hand for disbonding and cracking in accordance 
with the Accomplishment Instructions of Airbus Service Bulletin 
A300-53-229, Revision 5, dated April 8, 1997. If no disbonding and 
corrosion are found, repeat the inspection thereafter at intervals 
not to exceed 7 years or 12,000 flight cycles, whichever occurs 
first.
    (1) If no cracking is found and ``minor'' disbonding, as defined 
in Airbus Service Bulletin A300-53-229, Revision 5, dated April 8, 
1997, is found: Repeat the inspection thereafter at intervals not to 
exceed 1 year for areas below stringer 22, and at intervals not to 
exceed 2 years for areas above and including stringer 22. Doing a 
repair in accordance with Airbus Service Bulletin A300-53-229, 
Revision 5, dated April 8, 1997, terminates the repetitive 
inspections required by this paragraph for that area.
    (2) If no cracking is found and ``major'' disbonding, as defined 
in Airbus Service Bulletin A300-53-229, Revision 5, dated April 8, 
1997, is found: Within 1,000 flight cycles after doing the 
inspection, repair, in accordance with the Accomplishment 
Instructions of Airbus Service Bulletin A300-53-229, Revision 5, 
dated April 8, 1997.
    (3) If any cracking is found, repair prior to further flight, in 
accordance with Airbus Service Bulletin A300-53-229, Revision 5, 
dated April 8, 1997.
    (p) Although Airbus Service Bulletin A300-53-229, Revision 5, 
dated April 8, 1997; and Airbus Mandatory Service Bulletin A300-53-
0211, Revision 07, dated December 1, 2006; specify to submit certain 
information to the manufacturer, this AD does not include that 
requirement.

FAA AD Differences

    Note 1: This AD differs from the MCAI and/or service information 
as follows:
    (1) Although the MCAI or service information allows further 
flight after cracks are found during compliance with the required 
action, this AD requires that you repair the crack(s) before further 
flight.
    (2) The MCAI or service information does not include enforceable 
compliance times for certain actions; however, this AD requires that 
those actions be done at the enforceable times specified in this AD.
    (3) Although the MCAI or service information tells you to submit 
information to the manufacturer, paragraph (p) of this AD specifies 
that such submittal is not required.

Other FAA AD Provisions

    (q) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as 
appropriate. If sending information directly to the International 
Branch, send it to ATTN: Dan Rodina, Aerospace Engineer, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone 
(425) 227-2125; fax (425) 227-1149. Information may be e-mailed to: 
9-ANM-116-AMOC-REQUESTS@faa.gov. Before using any approved AMOC, 
notify your appropriate principal inspector, or lacking a principal 
inspector, the manager of the local flight standards district 
office/certificate holding district office. The AMOC approval letter 
must specifically reference this AD.
    (2) 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.
