14 CFR Part 39

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


Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt 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 proposed 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 
proposed AD would require 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 
proposing 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: We must receive comments on this proposed AD by April 9, 2012.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2011-0007R1, dated February 14, 2011 (referred 
to after this as ``the MCAI''), 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 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 
AD on the Aft Cargo Compartment Door.

docket.

Relevant Service Information

    Airbus has issued the following service information:
     All Operators Telex A330-52A3084, dated December 20, 2010 
(for Model A330-200 and A330-300 series airplanes);
     All Operators Telex A330-52A3085, dated December 20, 2010 
(for Model A330-200 and A330-300 series airplanes);
     All Operators Telex A340-52A4091, dated December 20, 2010 
(for Model A340-200 and A340-300 series airplanes); and
     All Operators Telex A340-52A4092, dated December 20, 2010 
(for Model A340-200 and A340-300 series airplanes).
    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 55 products of U.S. registry. We also estimate that 
it would take about 1 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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 proposed AD and placed it in the AD docket.
