14 CFR Part 39

[Docket No. FAA-2012-0152; Directorate Identifier 2011-NM-059-AD; 
Amendment 39-17092; AD 2012-12-12]
RIN 2120-AA64

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 series airplanes; Airbus Model A330-200 Freighter 
series airplanes; Airbus Model A330-300 series airplanes; Airbus Model 
A340-200 series airplanes; and Airbus Model A340-300 series airplanes. 
This AD was prompted by reports of sheared fasteners located on the 
outside skin of the forward cargo door and cracks on the frame fork 
ends, as well as cracks of the aft cargo door frame 64A. This AD 
requires performing a detailed inspection of the outer skin rivets at 
the frame fork ends of the forward and aft cargo door for sheared, 
loose, and missing rivets; repairing the outer skin rivets, if 
necessary; and performing repetitive inspections. We are issuing this 
AD to detect and correct sheared, loose, or missing fasteners on the 
forward and aft cargo door frame, which could result in the loss of 
structural integrity of the forward and aft cargo door.

DATES: This AD becomes effective July 30, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 30, 
2012.

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 February 23, 2012 
(77 FR 10691). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    Two operators have reported cases of some sheared fasteners on 
the outside skin of the forward cargo door, detected during walk 
around checks. Further inspections revealed crack findings on the 
frame (FR) fork ends.
    In addition, during a scheduled maintenance check, the aft cargo 
door frame 64A of an aeroplane has been found cracked for a length 
of more than 3 inches. Outer skin rivets were also found sheared. At 
time of findings the aeroplane had accumulated 10564 flight cycles 
(FC), i.e. below the 12000 FC threshold defined in DGAC [Direction 
G[eacute]n[eacute]rale de l'Aviation Civile] France AD F-2001-124(B) 
and DGAC France AD F-2001-126(B) [which corresponds with FAA AD 
2001-16-01, Amendment 39-12369 (66 FR 40874, August 6, 2001], which 
require a special detailed inspection of the aft cargo compartment 
door.
    In case of cracked or ruptured (forward or aft) cargo door 
frame, the loads will be transferred to the remaining structural 
elements. Such second load path is able to sustain the loads for a 
limited number of flight cycles only. Rupture of two vertical frames 
could result in the loss of the structural integrity of the forward 
or aft cargo door.
    For the above described reasons, this [EASA] AD requires 
repetitive detailed visual inspections of the aft and forward cargo 
doors outer skin for sheared, loose or missing rivets at all frame 
fork ends and the accomplishment of the applicable corrective 
actions [repair if necessary].
    This [EASA] AD is considered to be an interim action, further 
actions might be required to revise/supersede the above mentioned 
DGAC France ADs.
    This [EASA] AD is revised in order to recognize that aeroplanes 
on which Airbus modification 44852 has been embodied in production 
are not affected by the repetitive inspection requirements of this 
[EASA] AD on the Aft Cargo Compartment Door.

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 (77 FR 10691, February 23, 
2012) 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 the AD as proposed.

Clarification of the Repetitive Inspections

    For clarification purposes, we changed the interval for the 
repetitive inspections in paragraph (g) of this AD to the following: 
``* * * at intervals not to exceed 800 flight cycles.'' The repetitive 
interval was stated incorrectly in the NPRM (77 FR 10691, February 23, 
2012) as 800 ``total'' flight cycles.

Costs of Compliance

    We estimate that this AD will affect 55 products of U.S. registry. 
We also estimate that it will take about 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 of 
this AD to the U.S. operators to be $4,675, 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 proposed 
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 the NPRM (77 FR 10691, February 23, 
2012), the regulatory evaluation, any comments received, and other 
information. The street address for the Docket Operations office
