14 CFR Part 39

[Docket No. FAA-2005-22170; Directorate Identifier 2005-NM-073-AD; 
Amendment 39-14349; AD 2005-22-05]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A320-111, -211, -212, and 
-231 Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus Model A320-111, -211, -212, and -231 airplanes. This AD 
requires, for certain airplanes, modifying the cables and access holes 
to the inner tank fuel pumps; and, for certain other airplanes, 
inspecting the fuel pump access holes and modifying the access holes, 
if necessary. This AD results from fuel system reviews conducted by the 
manufacturer. We are issuing this AD to prevent chafing of the fuel 
pump cables, which could result in electrical arcing and possible 
ignition of fuel vapors and consequent explosion of the fuel tank.

DATES: This AD becomes effective November 30, 2005.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of November 30, 
2005.

ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility, U.S. 
Department of Transportation, 400 Seventh Street SW., Nassif Building, 
room PL-401, Washington, DC.
    Contact Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex,

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at http://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Management Facility office 
(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain Airbus Model 
A320-111, -211, -212, and -231 airplanes. That NPRM was published in 
the Federal Register on August 23, 2005 (70 FR 49213). That NPRM 
proposed to require, for certain airplanes, modifying the cables and 
access holes to the inner tank fuel pumps; and, for certain other 
airplanes, inspecting the fuel pump access holes and modifying the 
access holes, if necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment received. The 
commenter supports the NPRM.

Clarification of Alternative Method of Compliance (AMOC) Paragraph

    We have revised this action to clarify the appropriate procedure 
for notifying the principal inspector before using any approved AMOC on 
any airplane to which the AMOC applies.

Editorial Change

    As stated in the ``Relevant Service Information'' section of the 
NPRM, Airbus Service Bulletin A320-28-1054, dated August 23, 1993, 
describes procedures for performing an inspection, and ``as applicable, 
modifying the fuel pump access holes.'' We have revised paragraph 
(f)(2) of the final rule to state ``* * * modify the access holes, as 
applicable * * *'' instead of ``* * * modify the access holes, as 
necessary * * *.''

Conclusion

    We have carefully 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. 
We have determined that these changes will neither increase the 
economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    This AD will affect about 17 airplanes of U.S. registry. The 
actions will be performed at an average labor rate of $65 per work 
hour, and any needed parts will be supplied from operator inventory.
    For about 7 U.S.-registered airplanes subject to Airbus Service 
Bulletin A320-28-1008, Revision 1, dated April 10, 1989, the 
modification will take about 3 work hours. Based on these figures, the 
estimated cost of this modification for U.S. operators is $1,365, or 
$195 per airplane.
    For about 10 U.S.-registered airplanes subject to Airbus Service 
Bulletin A320-28-1054, dated August 23, 1993, the inspection will take 
about 1 work hour. Based on these figures, the estimated cost of this 
inspection for U.S. operators is $650, or $65 per airplane.

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;

[[Page 61721]]

    (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.

flight.

    Note 1: For the purposes of this AD, a general visual inspection 
is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normally available lighting 
conditions such as daylight, hangar lighting, flashlight, or 
droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''

No Reporting Requirement

    (g) Although Airbus Service Bulletin A320-28-1054, dated August 
23, 1993, describes procedures for reporting inspection findings to 
Airbus, this AD does not require that report.

Alternative Methods of Compliance (AMOCs)

    (h)(1) The Manager, International Branch, ANM-116, Transport 
Airplane Directorate, FAA, has the authority to approve AMOCs for 
this AD, if requested in accordance with the procedures found in 14
