Federal Aviation Administration (FAA), Department of Transportation (DOT).
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes; and A340-541 and A340-642 airplanes. This AD requires operators to revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate new information. This information includes, for all affected airplanes, decreased life limit values for certain components; and for Model A330-200 and -300 series airplanes, new inspections, compliance times, and new repetitive intervals to detect fatigue cracking, accidental damage, or corrosion in certain structures. This AD results from a revision to subsection 9-1 of the Airbus A330 and A340 Maintenance Planning Documents (MPD) for Life limits/Monitored parts, and subsection 9-2 of the Airbus A330 MPD for Airworthiness Limitations Items. We are issuing this AD to prevent fatigue cracking, damage, or corrosion, which could result in reduced structural integrity of these airplanes.
This AD becomes effective June 7, 2006.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of June 7, 2006.

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 all Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes; and A340-541 and A340-642 airplanes. That NPRM was published in the Federal Register on November 15, 2005 (70 FR 69288). That NPRM proposed to require operators to revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate new information.
We provided the public the opportunity to participate in the development of this AD. We have considered the comment received. Start Printed Page 25920
Request To Allow Single Inspection for Compliance With Tasks of Multiple Origins
Air Transportation Association (ATA), on behalf of Northwest Airlines, supports the intent of the NPRM, but has questions about implementing the AD. ATA's concern centers on the Airworthiness Limitations items (ALI) that require general visual inspections (GVI). ATA supports listing these inspections separately in an appropriate document so that they remain visible and will not be “lost” in the commenter's zonal inspection program. However, ATA would like the FAA to acknowledge that GVI tasks with multiple origins (ALI and maintenance review board (MRB)) that have identical accessibility only require a single GVI. ATA states that this single GVI constitutes full compliance with all applicable originating documents; separate GVIs are not required in order to show compliance with each originating document. ATA believes that accomplishing these GVIs in conjunction with each other will enhance safety, provided each GVI requirement is tracked separately. In other words, the ATA explains, an ALI requirement should be accomplished in conjunction with the zonal inspection program when appropriate so that the effectiveness of each inspection requirement will be maintained.
We acknowledge ATA's request. The zonal inspection program is a program that is unique to the commenter's airline. A single GVI can satisfy both the MRB zonal inspection and the ALI inspection as long as the inspection is done in the same area. However, the commenter must work with its Principal Maintenance Inspector for approval of that method of compliance. We have not changed the AD in this regard.
Explanation of Change in Applicability
We have added Airbus Model A330-302 and A330-303 airplanes to the applicability of the AD to more closely match the effectivity of the parallel French airworthiness directives. Neither of these models are on the U.S. Register. However, we have added them to the applicability to ensure that the unsafe condition is addressed if any Airbus Model A330-302 and A330-303 airplane is imported and placed on the U.S. Register in the future.
Clarification of Unsafe Condition
We have changed the AD to further clarify the end-level effect unsafe condition could have on the affected airplanes.
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
The following table provides the estimated costs for U.S. operators to comply with this AD.
|Action||Work hour||Average labor rate per hour||Parts||Cost per airplane||Number of U.S.-registered airplanes||Fleet cost|
|Revise the ALS||1||$65||None||$65||20||$1,300|
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

This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (h) of this AD. The request should include a description of changes to the required inspections that will ensure the continued damage tolerance of the affected structure. The FAA has provided guidance for this determination in Advisory Circular 25-1529.
(d) This AD results from a revision to subsection 9-1 of the Airbus A330 and A340 Maintenance Planning Documents (MPD) for Life limits/Monitored parts, and subsection 9-2 of the Airbus A330 MPD for Airworthiness Limitations Items. We are issuing this AD to prevent fatigue cracking, damage, or corrosion, which could result in reduced structural integrity of these airplanes.
