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 Freighter series airplanes; Model A330-200 and -
300 series airplanes; and Model A340-200 and -300 series airplanes. 
This proposed AD was prompted by a report of a manufacturing defect in 
certain rods installed in the belly fairing, which could lead to cracks 
at the crimped end of the rod. This proposed AD would require an 
inspection of the rods to determine the manufacturer; and for affected 
parts, an inspection for any cracking of the rods, and related 
investigative and corrective actions if necessary. We are proposing 
this AD to detect and correct cracking of the rods, which could result 
in rupture of rods that attach the belly fairing to the airframe, 
leading to separation of the belly fairing from the airframe, and 
consequent damage to airplane structure and airplane systems.

DATES: We must receive comments on this proposed AD by November 30, 
2012.

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 2012-0005, dated January 10, 2012 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    A rod manufacturing process defect has been identified at the 
supplier, Technical Airborne Components Industries (TAC), which 
could lead to cracks at the crimped end of the rod.
    A design review of all affected rods has demonstrated that 
rupture of rods which attach the belly fairing can lead to 
separation of the belly fairing from the airframe, which would 
constitute an unsafe condition.
    For the reasons described above, this AD requires detailed 
visual inspections of the 21 affected rods installed in the belly 
fairing for manufacturer identification, and if TAC is identified as 
manufacturer, or if the manufacturer cannot be identified, to 
further inspect the rods to find any crack, using a high frequency 
eddy current (HFEC) method and, depending on findings, 
accomplishment of the applicable [related investigative and] 
corrective actions, to ensure structural integrity of the belly 
fairing rods. This AD also prohibits installation of an affected TAC 
rod as replacement part in the belly fairing to all aeroplanes.

A design review of all affected rods has demonstrated that rupture of 
rods which attach the belly fairing can lead to separation of the belly 
fairing from the airframe, which can cause damage to airplane structure 
and airplane systems. The related investigative actions include an 
inspection to determine the manufacturer and an HFEC inspection of any 
affected replacement rod for any cracking. The corrective actions 
include replacing the cracked rod with a new rod. You may obtain 
further information by examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletins A330-53-3186 and 
A340-53-4185, both including Appendix 01, both Revision 01, both dated 
April 7, 2011. 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 54 products of U.S. registry. We also estimate that 
it would take about 13 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 $59,670, or $1,105 per product.
    In addition, we estimate that any necessary follow-on actions would 
take 28 work-hours and require parts costing $0, for a cost of $2,380 
per product. Where the service information lists required parts costs 
that are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. We have no way of determining the number of products that may 
need these actions.

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.
