14 CFR Part 39
[Docket No. FAA-2007-0171; Directorate Identifier 2007-NM-220-AD;
Amendment 39-15330; AD 2008-01-05]
RIN 2120-AA64
Airworthiness Directives; Airbus Model A310 Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), that applies to certain Airbus Model A310 series airplanes. That
AD currently requires modification of certain wires in the right-hand
(RH) wing. This new AD requires further modification by installing an
additional protection sleeve and segregating route 2S in the RH pylon
area. This AD results from analysis of wire routing that revealed that
route 2S of the fuel electrical circuit, located in the RH wing, does
not provide adequate separation of fuel quantity indication wires from
wires carrying 115-volt alternating current (AC). We are issuing this
AD to ensure that fuel quantity indication wires are properly separated
from wires carrying 115-volt AC. Improper separation of such wires, in
the event of wire damage, could lead to a short circuit and a possible
ignition source, which could result in a fire in the airplane.
DATES: This AD becomes effective February 20, 2008.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of February 20,
2008.
On September 3, 2004 (69 FR 45578, July 30, 2004), the Director of
the Federal Register approved the incorporation by reference of Airbus
Service Bulletin A310-28-2148, Revision 01, dated October 29, 2002.
ADDRESSES: For service information identified in this AD, contact
Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex, France.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that supersedes AD 2004-15-16, amendment
39-13750 (69 FR 45578, July 30, 2004). The existing AD applies to
certain Airbus Model A310 series airplanes. That NPRM was published in
the Federal Register on November 9, 2007 (72 FR 63506). That NPRM
proposed to continue to require modification of certain wires in the
right-hand (RH) wing. That NPRM also proposed to require further
modification by installing an additional protection sleeve and
segregating route 2S in the RH pylon area.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been received on the NPRM or
on the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
The following table provides the estimated costs for U.S. operators
to comply with this AD.
Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
Number of U.S.-
Action Work hours Average labor Parts Cost per registered Fleet cost
rate per hour airplane airplanes
--------------------------------------------------------------------------------------------------------------------------------------------------------
Modification (required by AD 2004-15-16)................ 35 $80 $4,459 $7,259 68 $493,612
Further Modification (new proposed action).............. 22 80 1,870 3,630 68 246,840
--------------------------------------------------------------------------------------------------------------------------------------------------------
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 have 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 DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and
(3) 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 AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
removing amendment 39-13750 (69 FR 45578, July 30, 2004) and by adding
the following new airworthiness directive (AD):
2008-01-05 Airbus: Amendment 39-15330. Docket No. FAA-2007-0171;
Directorate Identifier 2007-NM-220-AD.
Effective Date
(a) This AD becomes effective February 20, 2008.
Affected ADs
(b) This AD supersedes AD 2004-15-16.
Applicability
(c) This AD applies to Model A310 series airplanes, certificated
in any category, all certified models, all serial numbers, except
airplanes on which Airbus Service Bulletin A310-28-2148, Revision
02, dated March 9, 2007, has been done (Airbus Modifications 12427
and 12435).
Unsafe Condition
(d) This AD results from analysis of wire routing that revealed
that route 2S of the fuel electrical circuit, located in the right-
hand (RH) wing, does not provide adequate separation of fuel
quantity indication wires from wires carrying 115-volt alternating
current (AC). We are issuing this AD to ensure that fuel quantity
indication wires are properly separated from wires carrying 115-volt
AC. Improper separation of such wires,
[[Page 2797]]
in the event of wire damage, could lead to a short circuit and a
possible ignition source, which could result in a fire in the
airplane.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Restatement of Requirements of AD 2004-15-16
