ACTION: Final rule. AGENCY: We are superseding an existing airworthiness directive (AD) for certain Airbus Model A310 series airplanes. That AD currently requires, for certain airplanes, modifying the wire routing and installing additional protective sleeves. This new AD adds, for certain airplanes, modifying wire routings and installing a modified bracket. This AD was prompted by analyses of the wire routing showing that the route of the fuel electrical circuit in the right-hand wing must be modified in order to ensure better segregation between fuel quantity indication wires and the 115-volt alternating current wires. We are issuing this AD to prevent short circuits leading to arcing, and possible fuel tank explosion. SUMMARY: This AD becomes effective May 15, 2012. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of May 15, 2012. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of February 20, 2008 (73 FR 2795, January 16, 2008). The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of September 3, 2004 (69 FR 45578, July 30, 2004). ADDRESSES: You may examine the AD docket on the Internet at http:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC. FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer, International Branch, ANM–116, Transport Airplane Directorate, FAA, 1601 Lind Avenue SW., Renton, DATES: E:\FR\FM\10APR1.SGM 10APR1 21398 Federal Register / Vol. 77, No. 69 / Tuesday, April 10, 2012 / Rules and Regulations Washington 98057–3356; telephone (425) 227–2125; fax (425) 227–1149. 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 October 11, 2011 (76 FR 62653), and proposed to supersede AD 2008–01–05, Amendment 39–15330 (73 FR 2795, January 16, 2008). That NPRM proposed 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 must be modified in order to ensure better segregation between fuel quantity indication wires and the 115 Volts Alternating Current (VAC) wires of route 2S. This condition, if not corrected, could result in short circuits leading to arcing, and possible fuel tank explosion. To address this unsafe condition, ´ ´ [Direction Generale de l’Aviation Civile] DGAC France issued AD 2002–578(B) [which corresponds to FAA AD 2004–15–16, Amendment 39–13750 (69 FR 45578, July 30, 2004)] 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 [which corresponds to FAA AD 2008–01–05 (73 FR 2795, January 16, 2008)], which superseded DGAC France AD 2002–578(B), required those same actions, plus additional work as defined in Airbus SB A310–28–2148 Revision 02. Since EASA AD 2007–0230 was issued, an operator reported the possibility of chafing with the new routing of the wire bundle 2S in the RH wing pylon area to the generator wire bundle of engine 2. The modification of this zone was introduced by A310–28–2148 Revision 02 as additional work. Investigation 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 describe these changes, but a new interference has been found and requires updating SB A310–28–2148 to Revision 04 [or 05]. For the reasons described above, this new [EASA] AD retains the requirements of EASA AD 2007–0230, which is superseded, and requires the additional work as specified in Revision 04 [or 05] of Airbus SB A310–28– 2148. Required actions include modifying the wire routings and installing a modified bracket. 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 considered the comments received. Request To Reference Latest Service Information FedEx noted that Airbus has issued Mandatory Service Bulletin A310–28– 2148, Revision 06, dated August 31, 2011. We infer that FedEx is requesting that we reference Airbus Mandatory Service Bulletin A310–28–2148, Revision 06, dated August 31, 2011, in this AD. We agree and have reviewed Airbus Mandatory Service Bulletin A310–28– 2148, Revision 06, dated August 31, 2011. We have added this reference to paragraphs (g), (i), (j), and (n) of this AD as an optional source of service information for doing the required actions. Explanation of Additional Changes Made to This AD We have revised certain paragraph headers throughout this AD. We have also revised the wording in paragraphs (h) and (m) of this AD; this change has not changed the intent of those paragraphs. Conclusion We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the changes described previously— and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (76 FR 62653, October 11, 2011) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (76 FR 62653, October 11, 2011). Costs of Compliance We estimate that this AD will affect about 61 products of U.S. registry. The following table provides the estimated costs for U.S. operators to comply with this AD.

14 CFR Part 39

[Docket No. FAA-2011-1060; Directorate Identifier 2011-NM-015-AD; 
Amendment 39-16945; AD 2012-03-04]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for certain Airbus Model A310 series airplanes. That AD currently 
requires, for certain airplanes, modifying the wire routing and 
installing additional protective sleeves. This new AD adds, for certain 
airplanes, modifying wire routings and installing a modified bracket. 
This AD was prompted by analyses of the wire routing showing that the 
route of the fuel electrical circuit in the right-hand wing must be 
modified in order to ensure better segregation between fuel quantity 
indication wires and the 115-volt alternating current wires. We are 
issuing this AD to prevent short circuits leading to arcing, and 
possible fuel tank explosion.

DATES: This AD becomes effective May 15, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of May 15, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of February 20, 
2008 (73 FR 2795, January 16, 2008).
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
September 3, 2004 (69 FR 45578, July 30, 2004).

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 October 11, 2011 (76 
FR 62653), and proposed to supersede AD 2008-01-05, Amendment 39-15330 
(73 FR 2795, January 16, 2008). That NPRM proposed 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 must be modified in 
order to ensure better segregation between fuel quantity indication 
wires and the 115 Volts Alternating Current (VAC) wires of route 2S.
    This condition, if not corrected, could result in short circuits 
leading to arcing, and possible fuel tank explosion.
    To address this unsafe condition, [Direction 
G[eacute]n[eacute]rale de l'Aviation Civile] DGAC France issued AD 
2002-578(B) [which corresponds to FAA AD 2004-15-16, Amendment 39-
13750 (69 FR 45578, July 30, 2004)] 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 [which corresponds 
to FAA AD 2008-01-05 (73 FR 2795, January 16, 2008)], which 
superseded DGAC France AD 2002-578(B), required those same actions, 
plus additional work as defined in Airbus SB A310-28-2148 Revision 
02.
    Since EASA AD 2007-0230 was issued, an operator reported the 
possibility of chafing with the new routing of the wire bundle 2S in 
the RH wing pylon area to the generator wire bundle of engine 2. The 
modification of this zone was introduced by A310-28-2148 Revision 02 
as additional work. Investigation 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 describe 
these changes, but a new interference has been found and requires 
updating SB A310-28-2148 to Revision 04 [or 05].
    For the reasons described above, this new [EASA] AD retains the 
requirements of EASA AD 2007-0230, which is superseded, and requires 
the additional work as specified in Revision 04 [or 05] of Airbus SB 
A310-28-2148.

Required actions include modifying the wire routings and installing a 
modified bracket. 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 considered the comments received.

Request To Reference Latest Service Information

    FedEx noted that Airbus has issued Mandatory Service Bulletin A310-
28-2148, Revision 06, dated August 31, 2011.
    We infer that FedEx is requesting that we reference Airbus 
Mandatory Service Bulletin A310-28-2148, Revision 06, dated August 31, 
2011, in this AD. We agree and have reviewed Airbus Mandatory Service 
Bulletin A310-28-2148, Revision 06, dated August 31, 2011. We have 
added this reference to paragraphs (g), (i), (j), and (n) of this AD as 
an optional source of service information for doing the required 
actions.

Explanation of Additional Changes Made to This AD

    We have revised certain paragraph headers throughout this AD. We 
have also revised the wording in paragraphs (h) and (m) of this AD; 
this change has not changed the intent of those paragraphs.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the changes described previously--and minor editorial changes. 
We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (76 FR 62653, October 11, 2011) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 62653, October 11, 2011).

Costs of Compliance

    We estimate that this AD will affect about 61 products of U.S. 
registry. The following table provides the estimated costs for U.S. 
operators to comply with this 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:

[[Page 21399]]

    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.

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 (76 FR 62653, October 11, 
2011), the regulatory evaluation, any comments received, and other 
information. The street address for the Docket Operations office 
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will 
be available in the AD docket shortly after receipt.
