Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2012-03-04 for 
certain Airbus Model A310 series airplanes. AD 2012-03-04 required for 
certain airplanes, modifying the wire routing and installing additional 
protective sleeves. This new AD continues to require the actions in AD 
2012-03-04, and requires additional work for certain airplanes. This AD 
was prompted by reports of new interferences of newly routed wire 
bundle 2S. We are issuing this AD to prevent short circuits leading to 
arcing, and possible fuel tank explosion.

DATES: This AD becomes effective May 27, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 27, 
2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of May 15, 
2012 (77 FR 21397, April 10, 2012).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2012-03-04, Amendment 39-16945 (77 FR 21397, 
April 10, 2012). AD 2012-03-04 applied to certain Airbus Model A310 
series airplanes. The NPRM published in the Federal Register on January 
14, 2014 (79 FR 2391).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0188, dated September 19, 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:

    Within the scope of the Fuel System Safety Program (FSSP), 
analyses of the wire routing showed that the route 2S of the fuel 
electrical circuit in the Right Hand (RH) wing ensures insufficient 
segregation between fuel quantity indication wires and the 115 Volts 
Alternating Current (VAC) wires of route 2S which could, under 
certain conditions, lead to a short circuit and subsequent arcing, 
creating a potential ignition source in the fuel tank vapour space.
    This condition, if not detected, could result in a fuel tank 
explosion and consequent loss of the aeroplane.
    To address this potential unsafe condition, DGAC France issued 
[an] AD *** to require improvements of the design as specified in 
Airbus Service Bulletin (SB) A310-28-2148 original issue or Revision 
01. EASA AD 2007-0230 [(http://ad.easa.europa.eu/blob/easa_ad_2007_0230_Superseded.pdf/AD_2007-0230_1)], which superseded [a] 
DGAC France AD ***, [which] required those same actions, plus 
additional work 1, as defined in Airbus SB A310-28-2148 Revision 02.
    Since EASA AD 2007-0230 was issued, an operator reported the 
possibility of chafing between the new routing of the wire bundle 2S 
in the RH wing pylon area and the wire bundle of No.2 engine 
generator. The modification of this zone was introduced by Airbus SB 
A310-28-2148 Revision 02 as additional work 1. Investigation results 
showed that, to avoid the risk of chafing, the affected wiring 
harnesses must be installed at a higher position to provide 
sufficient clearance with the newly routed wire bundle 2S conduit.
    Airbus published Revision 03 of SB A310-28-2148 to implement 
these changes as additional work 2. Subsequently, a new potential 
interference due to insufficient clearance was found, which prompted 
Airbus to issue SB A310-28-2148 Revision 04.
    Prompted by these findings and actions, EASA issued AD 2011-0005 
[(http://ad.easa.europa.eu/blob/easa_ad_2011_0005_Superseded.pdf/AD_2011-0005_1)], retaining the requirements of 
EASA AD 2007-0230, which was superseded, and required the additional 
work 2 as specified in Revisions 03 and 04 of Airbus SB A310-28-
2148.
    Since EASA AD 2011-0005 was issued, several operators of 
aeroplanes not having been modified in-service through Airbus SB 
A310-36-2015, or without having Airbus modification 07633 applied in 
production, reported to have embodied Airbus SB A310-28-2148 at 
Revision 02 or Revision 03 on the aeroplane. However, the adequate 
instructions to avoid the new interferences were only introduced in 
Airbus SB A310-28-2148 Revision 04.
    For the reasons described above, this new [EASA] AD retains the 
requirements of EASA AD 2011-0005, which is superseded, and 
requires, for certain aeroplanes, the additional work 3 [segregating 
wire route 2S in the RH pylon area or modifying the wire routings] 
as defined in Airbus SB A310-28-2148 Revision 06. As SB A310-28-2148 
Revision 07 was issued to clarify the additional work 1, 2 and 3 
[segregating wire route 2S in the RH pylon area or modifying the 
wire routings] for aeroplanes that have previously embodied that SB 
at original issue, Revision 01 or Revision 02, this AD also 
clarifies the required additional work.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-1072-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 2391, January 14, 
2014) or on the determination of the cost to the public.

[[Page 22365]]

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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (79 FR 2391, January 14, 2014) for correcting the unsafe 
condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 2391, January 14, 2014).

Costs of Compliance

    We estimate that this AD affects 41 airplanes of U.S. registry.

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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2013-1072; or in person at the 
Docket Management Facility between 9 a.m. and 5 p.m., Monday through
