14 CFR Part 39

[Docket No. FAA-2014-0775; Directorate Identifier 2014-NM-046-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 A300 B4-600, B4-600R, and F4-600R series airplanes, Model 
A300 C4-605R Variant F airplanes (collectively called Model A300-600 
series airplanes), and Model A310 series airplanes. This proposed AD 
was prompted by reports of insufficient clearance for the electrical 
wiring bundles in the leading and trailing edges of the left and right 
wings. This proposed AD would require installation of new bracket 
assemblies to ensure adequate clearance between the wiring and the 
structure, and installation of protective split sleeves as mechanical 
protection to the electrical harnesses. We are proposing this AD to 
detect and correct insufficient clearance of electrical wiring bundles 
located in the leading and trailing edges of the left and right wings, 
which could lead to chafing damage and arcing, possibly resulting in an 
on-board fire.

DATES: We must receive comments on this proposed AD by January 5, 2015.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

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 2014-0034, dated February 5, 2014 (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:

    Following publication of FAA SFAR 88 (Special Federal Aviation 
Regulation 88) (http://rgl.faa.gov/Regulatory_and_Guidance_Library%5CrgFAR.nsf/0/EEFB3F94451DC06286256C93004F5E07?OpenDocument), EASA issued AD 2006-
0076 (http://ad.easa.europa.eu/ad/2006-0076) requiring inspection 
and corrective action to improve the explosion risk protection 
system for the left hand (LH) and right hand (RH) wings on A300, 
A300-600, A300-600ST and A310 aeroplanes.
    For A300-600, A300-600ST and A310 aeroplanes, the required 
detailed visual inspections of electrical bundles located in the 
leading and trailing edges of the RH and LH wings and a review of 
the wing electrical installation on the final assembly line have 
shown that the wing electrical installation does not comply with the 
minimum distance inspection criteria to the surrounding structure in 
a few wing locations.
    This condition, if not detected and corrected, could lead to 
damage on the electrical harnesses and on the surrounding structure.
    To address this unsafe condition, Airbus developed an 
improvement of the wing electrical installation to prevent possible 
chafing and subsequent damage to the electrical harnesses and 
surrounding structure.
    For the reasons described above, this [EASA] AD requires 
installation of new bracket assemblies to ensure the clearance 
between the wiring and the structure, and installation of protective 
split sleeves as mechanical protection to the electrical harnesses.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for

[[Page 69378]]

and locating Docket No. FAA-2014-0775.

Relevant Service Information

    Airbus has issued Service Bulletin A300-24-6103, Revision 02, 
including Appendix 01, dated February 7, 2013; and Service Bulletin 
A310-24-2105, Revision 01, including Appendix 01, dated December 11, 
2013. 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 these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 199 airplanes of U.S. 
registry.
    We also estimate that it would take about 37 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost up to 
$18,000 per product. Based on these figures, we estimate the cost of 
this proposed AD on U.S. operators to be $4,207,855, or $21,145 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 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.
