This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.
Federal Aviation Administration (FAA), Department of Transportation (DOT).
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A319-100 series airplanes, Model A320-111 airplanes, Model A320-200 series airplanes, and Model A321-100 series airplanes equipped with any additional center tank (ACT). This AD requires identifying the part number of the ACT and, for certain ACTs, replacing the outer ACT manhole cover and seal. This AD results from reports of an ACT fuel transfer failure due to air leakage around the seal of the outer manhole covers of the ACTs. We are issuing this AD to prevent this leakage, which could result in fuel or fuel vapor leaking into the cargo compartment, and consequent increased risk of a fire in the cargo compartment.
This AD becomes effective December 19, 2005.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of December 19, 2005.
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.

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.
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 A319-100 series airplanes, Model A320-111 airplanes, Model A320-200 series Start Printed Page 69068airplanes, and Model A321-100 series airplanes equipped with certain additional center tanks (ACT). That NPRM was published in the Federal Register on August 17, 2005 (70 FR 48336). That NPRM proposed to require identifying the part number (P/N) of the ACT and, for certain ACTs, replacing the outer ACT manhole cover and seal.
We provided the public the opportunity to participate in the development of this AD. We have considered the single comment received. The commenter supports the NPRM.
Additional Service Bulletin Information
After the NPRM was issued Airbus released Revision 02 of service bulletin A321-28-1105, dated March 11, 2005. We have reviewed it, and it is substantially similar to Revision 01, which was referred to in the NPRM as the acceptable source of service information. We have revised paragraph (g) of this AD to refer to Revision 02 of the service bulletin as the acceptable source of service information, and to give credit for doing Revision 01 before the effective date of 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.
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 change described previously. We have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
The following table provides the estimated costs for U.S. operators to comply with this AD.
|Action||Work hours||Average hourly labor rate||Parts||Cost per airplane||Number of U.S.-registered airplanes||Fleet cost|
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.
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.Start List of Subjects
