14 CFR Part 39

[Docket No. FAA-2005-21862; Directorate Identifier 2005-NM-091-AD; 
Amendment 39-14333; AD 2005-20-36]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A320-111 Airplanes; and 
Model A320-200, A321-100, and A321-200 Series 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 airplanes; and Model A320-200, A321-100, 
and A321-200 series airplanes. This AD requires installing a bonding 
lead between the low pressure valve and the adjacent pipe assembly in 
each wing. This AD results from fuel system reviews conducted by the 
manufacturer. We are issuing this AD to prevent an ignition source for 
fuel vapor in the wing, which could result in fire or explosion in the 
adjacent wing fuel tank.

DATES: This AD becomes effective November 16, 2005.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of November 16, 
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, 
France, for service information identified in this AD.

FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer, 
International Branch, ANM-116, FAA, Transport Airplane Directorate,

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 airplanes; and Model A320-200, A321-100, and A321-200 series 
airplanes. That NPRM was published in the Federal Register on July 19, 
2005 (70 FR 41352). That NPRM proposed to require installing a bonding 
lead between the low pressure valve and the adjacent pipe assembly in 
each wing.

Comments

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

Request to Allow Credit for Use of Original Issue of Service Bulletin

    One commenter requests that we give credit for actions accomplished 
prior to the effective date of the AD using Airbus Service Bulletin 
A320-28-1055, dated July 12, 1993. The commenter contends that such 
credit is permitted by French airworthiness directive F-2005-058, dated 
April 13, 2005.
    We agree with this request. We have reviewed the original issue of 
the service bulletin and determined that no significant technical 
changes were made in the issuance of Airbus Service Bulletin A320-28-
1055, Revision 1, dated March 8, 1994. Therefore, we have added new 
paragraph (g) to give credit as specified and re-identified existing 
paragraphs (g) and (h) to (h)(1) and (i) in this AD.

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.

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 403 airplanes of U.S. registry. The 
required

[[Page 59237]]

actions will take about 2 work hours per airplane, at an average labor 
rate of $65 per work hour. Required parts will be obtained from 
operator stores. Based on these figures, the estimated cost of the AD 
for U.S. operators is $52,390, or $130 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;
    (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.
