Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A330-200 Freighter series airplanes; Model A330-200 and -
300 series airplanes, and Model A340-200 and -300 series airplanes. 
This AD was prompted by reports of cracked adjacent frame forks of a 
forward cargo door. This AD requires repetitive detailed inspections 
for cracks and sheared, loose, or missing rivets of the forward cargo 
door and, for certain airplanes, of the aft cargo door, and repair if 
necessary. We are issuing this AD to detect and correct cracked or 
ruptured cargo door frames, which could result in reduced structural 
integrity of the forward or aft cargo door.

DATES: This AD becomes effective October 4, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 4, 
2013.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

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. 
The NPRM was published in the Federal Register on May 20, 2013 (78 FR 
29261). The NPRM proposed to correct an unsafe condition for the 
specified products. The European Aviation Safety Agency (EASA), which 
is the Technical Agent for the Member States of the European Community, 
has issued EASA Airworthiness Directive 2012-0274, dated December 21, 
2012 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    One A330 operator recently reported a case where two adjacent 
frame (FR) forks of a forward cargo door were found cracked. FR20B 
was found cracked through, FR21 was found cracked half through. At 
the time of the findings, the affected aeroplane had accumulated 
around 21 000 flight cycles (FC) and it had already been inspected 
in accordance with EASA AD 2011-0007R1 [(http://ad.easa.europa.eu/blob/easa_ad_2011_0007_R1.pdf/AD_2011-0007R1_1)] [which 
corresponds to FAA AD 2012-12-12, Amendment 39-17092 (77 FR 37797, 
June 25, 2012)] and ALI [airworthiness limitation instructions] Task 
523106-01-1. However, during those inspections, the forward cargo 
door handle access panel is not required to be removed, which 
explains why the cracks at these two internal frame locations were 
not detected.
    After further analysis, it was determined that, in case of 
cracked or ruptured (forward or aft) cargo door frame, the loads 
will be transferred to the remaining structural elements. However, 
the second load path is able to sustain the loads for a limited 
number of flight cycles only.
    This condition, if not detected and corrected, could lead to 
rupture of two vertical frames, resulting in reduced structural 
integrity of the forward or aft cargo door.
    To address this condition, Airbus issued four separate Alert 
Operators Transmissions (AOT), giving instructions for repetitive 
inspections of the affected areas.
    For the reasons described above, this [EASA] AD requires 
repetitive detailed visual inspections of aft cargo door at FR60 and 
FR60A [for certain airplanes] and forward cargo door at FR21 and 
FR20B [for all airplanes], where the cargo door handle access panels 
are located, as follow:

--Outer skin rivets for sheared, loose or missing rivets at frame 
fork ends,
--whole inner forks for cracks and for sheared, loose or missing 
rivets at frame web and flange after removal of handle access 
panels, and

the accomplishment of the applicable corrective actions [which 
include repair, in accordance with a method approved by the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA.]
    Note: Accomplishment of the above inspections does not cancel 
accomplishment of the inspections as required by EASA [AD] 2011-
0007R1, nor accomplishment of those in accordance with ALI Task 
523106-01-1.

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 (78 FR 29261, May 20, 
2013) 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 this AD as proposed-except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 29261, May 20, 2013) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 29261, May 20, 2013).

Costs of Compliance

    We estimate that this AD affects 66 airplanes of U.S. registry. We 
also estimate that it takes 1 work-hour per product to comply with the 
basic requirements of this AD. The average labor rate is $85 per work-
hour. Based on these figures, we estimate the cost on U.S. operators to 
be $5,610, or $85 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this 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 that 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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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 this AD, the MCAI, the regulatory 
evaluation, any comments received, and other information. The street
